The cost of one movie ticket, including sales tax, is $13.02
The cost of the movie ticket is $12.00, and the sales tax rate is 8.5%. To find the amount of sales tax on the ticket, we can multiply the ticket price by the tax rate:
Sales tax = 12.00 * 0.085
= 1.02
So the sales tax on the ticket is $1.02.
To find the total cost of the ticket, we add the ticket price to the sales tax:
Total cost = 12.00 + 1.02
= 13.02
Therefore, the cost of one movie ticket, including sales tax, is $13.02.

I have tried doing this question for 20 minutes but I just can't get the answer, (add maths circular measure)
the answer is 17.2cm² supposedly
Answer:
17.2 cm²
Step-by-step explanation:
Alr let me try
The angle is 1.2 you got it right. The rest is in the pics
Answer: A(shaded)=17.15 cm²
Step-by-step explanation:
What you did so far is correct.
Given:
r=5
s=6
Solve for Ф angle:
s=[tex]\frac{part circle}{wholecircle} 2\pi r[/tex] This way help you find the portion/percent you want
6=(Ф/360) (2[tex]\pi[/tex]5) >solve for Ф Divide by (2[tex]\pi[/tex]5) and multiply by 360
Ф=68.75
Solve for pie/sector
Now that you have the angle, you can use the same concept for area
Area of sector = [tex]\frac{part circle}{wholecircle} \pi r^{2}[/tex]
Area of sector = [tex]\frac{68.75}{360} \pi 5^{2}[/tex]
Area of sector = 15.0 cm²
Now let find y so we can plug into area of triangle
use tan Ф = opposite/adjacent
tan 68.75 = y/5
y=5 * tan 68.75
y=12.86 cm
Area of triangle = 1/2 b h b=y=12.86 h =5
Area of triangle = 1/2* 12.86*5
Area of triangle = 32.15 cm²
Now subtract area of sector from triangle
A(shaded)=A(triangle)-A(sector)
A(shaded)=32.15- 15.0
A(shaded)=17.15 cm²
The table gives a set of outcomes and their probabilities. Let a be the event "the outcome is a divisor of 4". Let b be the event "the outcome is prime". Find p(a|b)
The probability that the outcome is a divisor of 4 given that it is prime is 0.125, or 12.5%.
Since we are given the probabilities of different outcomes, we can use the definition of conditional probability to find p(a|b), which represents the probability that the outcome is a divisor of 4 given that it is prime.
The formula for conditional probability is:
p(a|b) = p(a ∩ b) / p(b)
where p(a ∩ b) represents the probability of both events happening simultaneously.
Looking at the table of outcomes and their probabilities, we can see that there are four prime numbers: 2, 3, 5, and 7. Of these, only 2 is a divisor of 4.
Therefore, p(a ∩ b) is the probability that the outcome is 2, which is 0.1.
The probability of the outcome being prime is the sum of the probabilities of the four prime outcomes, which is:
p(b) = 0.1 + 0.2 + 0.3 + 0.2 = 0.8
Substituting these values into the formula for conditional probability, we get:
p(a|b) = p(a ∩ b) / p(b) = 0.1 / 0.8 = 0.125
Therefore, the probability that the outcome is a divisor of 4 given that it is prime is 0.125, or 12.5%.

Solid metal support poles in the form of right cylinders are made out of metal with a
density of 6.3 g/cm³. This metal can be purchased for $0.30 per kilogram. Calculate
the cost of a utility pole with a diameter of 42 cm and a height of 740 cm. Round your
answer to the nearest cent. (Note: the diagram is not drawn to scale)
Answer:Therefore, the cost of a utility pole with a diameter of 42 cm and a height of 740 cm is approximately $1957.43.
Step-by-step explanation:First, we need to calculate the volume of the cylinder-shaped utility pole:
The radius of the pole is half the diameter, so it's 42 cm / 2 = 21 cm.
The height of the pole is 740 cm.
The volume of a cylinder is given by the formula V = πr²h, where π is approximately 3.14, r is the radius, and h is the height.
Substituting the values we have, we get V = 3.14 x 21² x 740 = 1,034,462.4 cm³.
Now we can calculate the mass of the pole:
The density of the metal is 6.3 g/cm³, which means that 1 cm³ of the metal has a mass of 6.3 g.
The volume of the pole is 1,034,462.4 cm³, so its mass is 6.3 x 1,034,462.4 = 6,524,772.72 g.
Next, we convert the mass to kilograms and calculate the cost:
1 kg is equal to 1000 g, so the mass of the pole in kilograms is 6,524,772.72 g / 1000 = 6524.77 kg.
The cost of the metal is $0.30 per kilogram, so the cost of the pole is 6524.77 kg x $0.30/kg = $1957.43.
9. the square footage and monthly rental of 15 similar one-bedroom apartments yield the linear
regression formula y = 1.3485x + 840.51, where x represents the square footage and y represents
the monthly rental price. round answers to the nearest whole number.
Based on the linear regression formula y = 1.3485x + 840.51, you can calculate the monthly rental price (y) for a one-bedroom apartment by plugging in the square footage (x) of the apartment.
The linear regression formula for the 15 similar one-bedroom apartments is y = 1.3485x + 840.51, where x represents the square footage and y represents the monthly rental price. This means that for every square foot increase in the apartment size, the monthly rental price is predicted to increase by $1.35.
The y-intercept of the formula is $840.51, which represents the predicted monthly rental price for an apartment with 0 square footage (this is not possible in reality, but is used in the formula for mathematical purposes). To get the rental price, round your answer to the nearest whole number. For example, if an apartment has 500 square feet, you'd calculate: y = 1.3485(500) + 840.51 ≈ 1344.76, which rounds to $1,345 as the monthly rental price.

The number of bacteria in a certain colony doubles every 5 days. At the same rate, how long will the colony need to triple in number?
The colony will need to triple in number after about 7.58 days.
How to find the number of bacteria in a certain colony?Since the number of bacteria doubles every 5 days, we can write the relationship between the number of bacteria and time as an exponential function:
N(t) = N0 x 2^(t/5)
where N0 is the initial number of bacteria and t is the time in days.
To find out how long it will take for the colony to triple in number, we need to solve the equation:
N(t) = 3N0
Substituting the expression for N(t) from above, we get:
N0 x 2^(t/5) = 3N0
Dividing both sides by N0, we get:
2^(t/5) = 3
Taking the logarithm of both sides (with base 2) gives:
t/5 = log2(3)
Multiplying both sides by 5, we get:
t = 5 x log2(3)
Using a calculator or a computer program to evaluate the logarithm, we get:
t ≈ 7.58
Therefore, the colony will need to triple in number after about 7.58 days.

To conduct the science experiment, the temperature needs to be decreased from 36°C at a rate of 4°C every hour.
So, after 1 hour, the temperature will be 36°C - 4°C = 32°C. After 2 hours, the temperature will be 32°C - 4°C = 28°C. Continuing this pattern, after 10 hours, the temperature will be 36°C - (4°C x 10) = 36°C - 40°C = -4°C.

Initial Balance (dollars) $5,000 $5,000 $5,000 $5,000 Monthly Deposit (dollars) $100 $200 $300 $400 Account Value in Five Years (dollars) $11,000 $17,000 $23,000 $29,000 Problem The student wants to have enough money saved in four years to pay the tuition and fees for her first two years of college. Based on the table, what is the minimum amount she should deposit in the savings account every month? A $200 B $100 C $300 D $400
$23,000 is more than the $19,000 needed for tuition and fees for the first two years, the minimum amount the student should deposit in the savings account every month is $300 (option C).
What is the account value in five years with a monthly deposit of $300?The minimum monthly deposit the student should make in order to save enough money for her first two years of college tuition and fees in four years, we need to calculate how much she would need to have in her savings account at the end of four years.
Since the student estimated she needs $9,500 per year for tuition and fees, she will need $19,000 for her first two years. Since she already has $5,000 in her savings account, she needs to save an additional $14,000 in four years.
Looking at the table, we can see that the account value in five years with a monthly deposit of $200 is $17,000. To find out how much the account value would be in four years, we need to calculate the future value of $17,000 with a 4-year time frame and an annual interest rate of 0%, which gives:
Future value = $17,000 x (1 + 0%)^(4 x 12/12) = $17,000
Since the account value with a $200 monthly deposit is only $17,000 after 5 years, which is not enough to cover the $19,000 needed for tuition and fees for the first two years, the student needs to make a higher monthly deposit.
Looking at the table again, we can see that the account value in five years with a monthly deposit of $300 is $23,000. To find out how much the account value would be in four years, we need to calculate the future value of $23,000 with a 4-year time frame and an annual interest rate of 0%, which gives:
Future value = $23,000 x (1 + 0%)^(4 x 12/12) = $23,000
$23,000 is more than the $19,000 needed for tuition and fees for the first two years, the minimum amount the student should deposit in the savings account every month is $300 (option C).

The shape of the cross section of a right rectangular pyramid sliced vertically (down) by a plane not passing through the vertex of the pyramid m is a trapezoid. (A)
This is because when a pyramid is sliced vertically, the resulting cross section is always a two-dimensional representation of the pyramid's base.
Since the base of a right rectangular pyramid is a rectangle, slicing it vertically will result in a trapezoid-shaped cross section. The top and bottom sides of the trapezoid will be parallel, and the other two sides will be slanted.
In a right rectangular pyramid, the vertex m is located directly above the center of the rectangle base. When a plane is passed through this vertex, it will result in a triangular cross section.

Franklin is helping his aunt sew a lace border onto 2 quilts. Each quilt is 2. 2 meters wide by 2. 7 meters long. At the craft store, they buy a 20-meter roll of lace. To their surprise, they use up almost all of it. How many millimeters of lace do they have left after finishing the quilts?
The amount in millimeters of lace they have left after finishing the quilts is 400 millimeters.
Determine how much lace is needed for each quilt. Each quilt has a perimeter that we need to cover with lace. The perimeter is the sum of all sides of a rectangle, which is (2 x width) + (2 x length).
Each quilt is 2.2 meters wide and 2.7 meters long. So, the perimeter of one quilt is (2 x 2.2) + (2 x 2.7) = 4.4 + 5.4 = 9.8 meters.
Since there are 2 quilts, the total lace needed for both quilts is 9.8 meters x 2 = 19.6 meters.
They bought a 20-meter roll of lace. To find out how much lace is left, subtract the total lace used from the initial length of the roll: 20 meters - 19.6 meters = 0.4 meters.
To convert this to millimeters, multiply by 1,000: 0.4 meters x 1,000 = 400 millimeters.

twice as many, one 3 times, one 4 times, one 5 times and one 6 times as many biscuits as on
Saturday. Who baked the most biscuits on Saturday?
(A) Anna (8) Berta (C) Charlie (D) David (E) Elisa
At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.
To determine who baked the most biscuits on Saturday, we need to calculate how many biscuits each child had at the end of the weekend.
Anna had 24 biscuits, Berta had 25, Charlie had 26, David had 27, and Elisa had 28.
Let's start with the child who had twice as many biscuits as on Saturday. We can divide their total number of biscuits by 2 to get the number they had on Saturday.
If we try this calculation for each child, we find that only Elisa's total number of biscuits (28) is evenly divisible by 2. Therefore, Elisa must be the child who had twice as many biscuits as on Saturday, meaning she had 14 biscuits on Saturday.
We can use a similar process to determine how many biscuits each child had on Saturday:
- The child who had three times as many biscuits as on Saturday must have had a total of 42 biscuits, which means they had 14 biscuits on Saturday.
- The child who had four times as many biscuits as on Saturday must have had a total of 56 biscuits, which means they had 14 biscuits on Saturday.
- The child who had five times as many biscuits as on Saturday must have had a total of 70 biscuits, which means they had 14 biscuits on Saturday.
- The child who had six times as many biscuits as on Saturday must have had a total of 84 biscuits, which means they had 14 biscuits on Saturday.
Now we can add up the number of biscuits each child had on Saturday:
- Anna had 24 biscuits.
- Berta had 25 biscuits.
- Charlie had 26 biscuits.
- David had 27 biscuits.
- Elisa had 14 biscuits.
Therefore, David baked the most biscuits on Saturday with 27.
To determine who baked the most biscuits on Saturday, we need to consider the information given about the multiplication factors (twice, 3 times, 4 times, 5 times, and 6 times) and the initial number of biscuits baked by each child.
1. Anna baked 24 biscuits.
2. Berta baked 25 biscuits.
3. Charlie baked 26 biscuits.
4. David baked 27 biscuits.
5. Elisa baked 28 biscuits.
Now, let's apply the multiplication factors and see which child had the most biscuits at the end of the weekend:
1. Anna: 24 x 2 = 48
2. Berta: 25 x 3 = 75
3. Charlie: 26 x 4 = 104
4. David: 27 x 5 = 135
5. Elisa: 28 x 6 = 168

A spinner has 10 equally sized sections, 6 of which are gray and 4
of which are blue. The spinner is spun twice. What is the probability that the first spin lands on blue and the second spin lands on gray.
Step-by-step explanation:
since both spins are independent events (one does not have any impact on the other), the sequence does not matter. the probability of first blue and then gray is the same as first gray and then blue.
it is the probability of getting 1 gray and 1 blue result.
a probability is always the ratio
desired cases / totally possible cases.
since 6/10 of the area of the spine are gray, and 4/10 of the area are blue, the probability for any single spin to result in gray is 6/10 = 3/5 = 0.6.
and the probability to result in blue is 4/10 = 2/5 = 0.4
the probability to get 1 gray and 1 blue is then the product of both probabilities :
0.6 × 0.4 = 0.24
it is like rolling a die twice and asking for e.g. two 6s or any other combination of 2 specific numbers. that probability is
1/6 × 1/6 = 1/36
FYI :
the probability of getting gray twice is then
0.6 × 0.6 = 0.36
the probability of getting blue twice is
0.4 × 0.4 = 0.16
as mentioned to get gray first and blue second is
0.6 × 0.4 = 0.24
to get blue first and gray second
0.4 × 0.6 = 0.24
and these are all the possible results you can get in 2 spins.
therefore, the probability for any of them is
0.36 + 0.16 + 0.24 + 0.24 = 1
The Louvre is an art museum in Paris. A glass square base pyramid sits in front of the entrance to the museum. If the pyramid is 35 meters wide at the base and 20. 6 meters tall, what was the minimum amount of glass needed to construct the pyramid?
The minimum amount of glass needed to construct the Louvre pyramid is approximately 3133 square meters.
What is the minimum amount of glass needed to construct the glass pyramid in front of the Louvre museum in Paris, if the pyramid is 35 meters wide at the base and 20.6 meters tall?
The surface area of a square base pyramid can be calculated by adding the area of the base to the sum of the areas of the four triangular faces.
The area of the square base is simply the width of the base squared:
Area_base = (35 m)^2 = 1225 square meters
The area of each triangular face can be calculated using the formula:
Area_triangle = (1/2) * base * height
For the Louvre pyramid, the base of each triangular face is equal to the width of the base of the pyramid, which is 35 meters. The height of each triangular face can be found using the Pythagorean theorem:
[tex]height^2 = (1/2 * width)^2 + height^2[/tex]
[tex]height = sqrt((1/2 * 35 m)^2 + (20.6 m)^2)[/tex]
height = 29.2 m
Therefore, the area of each triangular face is:
Area_triangle = (1/2) * (35 m) * (29.2 m) = 508.5 square meters
The total surface area of the pyramid is:
Surface_area = Area_base + 4 * Area_triangle
Surface_area = 1225 + 4 * 508.5
Surface_area = 3133 square meters
Since the pyramid is made of glass, we need to calculate the minimum amount of glass needed to construct it. Assuming the glass is thin and flat, we can simply use the surface area of the pyramid to estimate the amount of glass needed.

The following table shows the weight of a cat in pounds and the corresponding number of cans of cat food to be given each day.
To complete the table, we need to use the information that the directions on the small cans of cat food say to feed a cat 1 can of food each day for every 4 pounds of body weight.
For example, for a cat weighing 4 pounds, we need to give 1 can of food each day.
For a cat weighing 5 pounds, we need to give more than 1 can but less than 2 cans of food each day.
To find the exact number of cans, we can use the formula:
cans per day = weight in pounds / 4
Substituting the given values, we get:
cans per day = 5 / 4
cans per day = 1.25
Therefore, for a cat weighing 5 pounds, we need to give 1.25 cans of food each day. We can round this to the nearest tenth to get 1.3 cans per day.
Similarly, we can use the formula to complete the rest of the table:
KIT-E-KAT weight in pounds cans per day
4 1
5 1.3
6 1.5
7 1.8
8 2
9 2.3
10 2.5
11 2.8
12 3
13 3.3
14 3.5
15 3.8
Therefore, the completed table shows the weight of a cat in pounds and the corresponding number of cans of cat food to be given each day.

how much soda do you need if you buy 20 bags of 4 bags of hot chips and 3 bottles of soda.
If each bag of hot chips requires around 500 ml of soda to drink with, then 46,000 ml of soda would be needed to buy 20 bags of 4 bags of hot chips and 3 bottles of soda.
To determine how much soda is needed if you buy 20 bags of 4 bags of hot chips and 3 bottles of soda, we need to know the volume of each bottle of soda.
Assuming each bottle of soda contains 2 liters of soda, the total volume of soda needed can be calculated as follows:
One bag of hot chips contains 4 bags of chips.So, 20 bags of hot chips contain 20 x 4 = 80 bags of chips.Each bag of chips may require around 500 ml of soda to drink with.Therefore, the total soda needed for all bags of chips is 80 x 500 ml = 40,000 ml.Three bottles of soda are also purchased, which contain a total of 3 x 2000 ml = 6000 ml.The total soda needed is the sum of the soda needed for the chips and the soda purchased, which is 40,000 ml + 6000 ml = 46,000 ml.To know more about volume, refer to the link below:

Assume that a procedure yields a binomial distribution with n trials and a probability of success of p. use a binomial probability table to find the probability that the number of successes x is exactly .
To find the probability that the number of successes x is exactly a certain value in a binomial distribution with n trials and a probability of success of p, we can use a binomial probability table. The table will provide us with the probability of getting x successes out of n trials, given a specific value of p.
For example, let's say we want to find the probability of getting exactly 3 successes in a binomial distribution with 10 trials and a probability of success of 0.5. We can use a binomial probability table to find the probability of getting exactly 3 successes, which is 0.117.
It is important to note that the probability of getting a specific number of successes in a binomial distribution is dependent on both the number of trials and the probability of success. Therefore, if we change either of these values, the probability of getting a certain number of successes will also change.

The am between two number exceeds their gm by 2 and the gm exceed the hm by 1.8 find the number
The unknown number x = (6.1 ± sqrt(6.
How to find the unknown numberLet's call the two numbers x and y.
We are given:
AM (Arithmetic Mean) between x and y exceeds their GM (Geometric Mean) by 2:
(x + y)/2 - sqrt(xy) = 2
GM between x and y exceeds their HM (Harmonic Mean) by 1.8:
sqrt(xy) - 2xy/(x+y) = 1.8
We can solve for one variable in terms of the other from the second equation and substitute into the first equation to solve for the remaining variable. Let's solve for y in terms of x from the second equation:
sqrt(xy) - 2xy/(x+y) = 1.8
sqrt(xy)(x+y) - 2xy = 1.8(x+y)
sqrt(xy)x + sqrt(xy)y - 2xy = 1.8x + 1.8y
sqrt(xy)(x+y-1.8) = 0.2x + 0.8y
x+y-1.8 = (0.2/0.8)sqrt(xy)(x+y-1.8)
x+y-1.8 = 0.25sqrt(xy)(x+y-1.8)
4x + 4y - 7.2 = sqrt(xy)(x+y)
Now we can substitute this expression for sqrt(xy)(x+y) into the first equation and solve for x:
(x + y)/2 - sqrt(xy) = 2
(x + y)/2 - (4x + 4y - 7.2)/4 = 2
2(x + y) - (4x + 4y - 7.2) = 8
12.2 = 2x + 2y
6.1 = x + y
Now we can substitute x + y = 6.1 into the expression we derived for sqrt(xy)(x+y) to solve for sqrt(xy):
4x + 4y - 7.2 = sqrt(xy)(x+y)
4x + 4y - 7.2 = sqrt(xy)(6.1)
sqrt(xy) = (4x + 4y - 7.2)/6.1
Finally, we can substitute both x + y = 6.1 and sqrt(xy) = (4x + 4y - 7.2)/6.1 into the equation sqrt(xy) - 2xy/(x+y) = 1.8 and solve for y:
sqrt(xy) - 2xy/(x+y) = 1.8
(4x + 4y - 7.2)/6.1 - 2xy/6.1 = 1.8
4x + 4y - 7.2 - 12.2xy = 11.38
4x + 4y - 11.38 = 12.2xy
4x + 4(6.1 - x) - 11.38 = 12.2xy (substituting x + y = 6.1)
xy = 4.08
Now we know that xy = 4.08, and we can use this to solve for x and y:
y = 6.1 - x
xy = 4.08
x(6.1 - x) = 4.08
6.1x - x^2 = 4.08
x^2 - 6.1x + 4.08 = 0
We can solve for x using the quadratic formula:
x = (6.1 ± sqrt(6.

Question 7 Determine the way in which the line (x, y, z) = (2, -3, 0] + k[-1, 3, -1) intersects the plane [x, y, 2] = [4, -15, -8] + s[1, -3, 1] + t[2, 3, 1), if at all. [2T/2A] , - No text entered -
The line intersects the plane at the point (-4, 15, -6).
How to find the intersection of line in given plane?The line (x, y, z) = (2, -3, 0) + k(-1, 3, -1) can be expressed parametrically as:
x = 2 - k
y = -3 + 3k
z = k
The plane [x, y, 2] = [4, -15, -8] + s[1, -3, 1] + t[2, 3, 1) can be expressed in scalar form as:
x + y - 2z = 14 + s - 2t
To find the intersection of the line and the plane, we can substitute the parametric equations of the line into the scalar equation of the plane:
(2 - k) + (-3 + 3k) - 2k = 14 + s - 2t
Simplifying this equation, we get:
-4k + 3 = 14 + s - 2t
We can also express the line and plane equations in vector form:
Line: r = (2, -3, 0) + k(-1, 3, -1) = (2-k, -3+3k, k)
Plane: r = (4, -15, -8) + s(1, -3, 1) + t(2, 3, 1) = (4+s+2t, -15-3s+3t, -8+s+t)
To find the intersection of the line and the plane, we need to find the values of k, s, and t that satisfy both equations simultaneously. We can do this by equating the vector forms of the line and plane and solving for k, s, and t:
2 - k = 4 + s + 2t
-3 + 3k = -15 - 3s + 3t
k = -8 - s - t
Substituting k into the first equation, we get:
2 + 8 + s + t = 4 + s + 2t
Simplifying this equation, we get:
t = 4
Substituting t = 4 and k = -8 - s - t into the second equation, we get:
-3 + 3(-8 - s - 4) = -15 - 3s + 3(4)
Simplifying this equation, we get:
s = -2
Substituting t = 4 and s = -2 into the first equation, we get:
k = 8 - s - t = 8 + 2 - 4 = 6
Therefore, the line intersects the plane at the point (x, y, z) = (2, -3, 0) + 6(-1, 3, -1) = (-4, 15, -6).
So the line intersects the plane at the point (-4, 15, -6).

The quotient is -58x2 + 131x - 234 with a remainder of -5898.To solve this problem, we need to use long division. The dividend is 223 + 3x2 + 5x - 4 and the divisor is 22 + 2 + 1, which simplifies to 25.
We start by dividing 2 into 22, which gives us 11. We then write 11 above the 2 and multiply it by 25, which gives us 275. We subtract 275 from 223, which gives us -52. We bring down the 3, which gives us -523. We then repeat the process by dividing 2 into 52, which gives us 26. We write 26 above the 5 and multiply it by 25, which gives us 650. We subtract 650 from -523, which gives us -1173. We bring down the 1, which gives us -11731. We divide 2 into 117, which gives us 58.
We write 58 above the x and multiply it by 25, which gives us 1450. We subtract 1450 from -1173, which gives us -2623. We bring down the -4, which gives us -26234. We divide 2 into 262, which gives us 131. We write 131 above the 5 and multiply it by 25, which gives us 3275. We subtract 3275 from -2623, which gives us -5898.

Question content area top Part 1 Point B has coordinates (3,2). The x-coordinate of point A is −9. The distance between point A and point B is 15 units. What are the possible coordinates of point A
The possible coordinates of point A are (-9, -7) and (-9, 11).
What are coordinates?Coordinates refers to a set of numbers that are used to identify the position of a point in a space, usually defined by an x-axis, y-axis, and in sometimes a z-axis.
Let the y-coordinate of point A be y. Then the coordinates of point A are (-9, y).
Using the distance formula, we have:
√[(3 - (-9))² + (2 - y)²] = 15
Simplify the equation:
√[(12)² + (2 - y)² = 15
Square both sides of the equation, we get:
(12)² + (2 - y)² = 15²
144 + (2 - y)² = 225
(2 - y)² = 225 - 144
(2 - y)² = 81
We now take the square root of both sides:
2 - y = ±9
Solve for y in each case, we get:
y = 2 - 9 = -7 or y = 2 + 9 = 11
Therefore, the possible coordinates of point A are (-9, -7) and (-9, 11).
