Can I Have The Answer? Its For Completing The Square

Answers

Answer 1

So, the equation of the given curve is a circle centered at (-13, 13) with a radius of 3. Therefore, the correct option is:

[tex](x + 13) ^ 2 + (y - 13) ^ 2 = 9[/tex].

What is equation?

An equation is a mathematical statement that shows the equality between two expressions, typically separated by an equal's sign (=). Equations are used to represent a wide range of mathematical and scientific relationships, such as physical laws, chemical reactions, and statistical models. The expressions on either side of the equals sign can contain variables, constants, and mathematical operations, and solving the equation involves finding the value or values of the variables that make the equation true. Equations can take many forms, including linear equations, quadratic equations, trigonometric equations, and differential equations, among others.

To determine which option is correct, we can try to convert the given equation to the standard form of the equation of a circle, which is:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

where (h, k) is the center of the circle and r is the radius.

We can complete the square for the given equation by adding and subtracting appropriate constants:

[tex]x^2 + 26x + y^2 - 26y + 329 = 0[/tex]

[tex](x^2 + 26x + 169) + (y^2 - 26y + 169) = -329 + 2(169)[/tex]

[tex](x + 13)^2 + (y - 13)^2 = 9[/tex]

what sample size is needed to achieve a margin of error of .05 for a 90% confidence interval for a proportion when previous studies have shown the proportion of interest to be near .25.

Answers

The sample size is needed to achieve a margin of error of .05 for a 90% confidence interval for a proportion of interest to be near 0.25 is equals to the 203.

From the above problem we have,

Mardin of error, E = 0.05

confidence interval, α = 90%

proportion of interest, p = 0.25

We have to determine the sample size.

Using the formula for minimum sample size is written as n = (Z² × p(1 -p)]/E² --(1)

Using the Z-distribution table and the z-score value for 90% is equals to 1.645.

Plug all known values in above equation,

=> n = [(1.645)² × 0.25 ( 1 - 0.25)]/(0.05)²

=> n = (1.645)² × 0.25 ×0.75/(0.05)²

=> n = 0.5074/0.0025

=> n = 202.96 ~ 203

Hence, required sample value is 203

At a movie theater, 2 medium drinks and a large popcorn costs $13.85. At the same theater, a family bought 3 medium drinks and 2 large popcorns for a total of $23.90. Which system of equations could be used to find x, the cost of a medium drink and y, the cost of a large popcorn?
A) 2x + y = 13.85
3x + 2y = 23.9
B) 3x + 2y = 13.85
2x + y = 23.9

C) x + 2y = 13.85
3x + 2y = 23.9

D) 2x + y = 13.85
2x + 3y = 23.9

Answers

The correct system of equations that could be used to find x, the cost of a medium drink, and y, the cost of a large popcorn, is:

A) 2x + y = 13.85 3x + 2y = 23.9

To arrive at these equations, you can use the information given in the question to set up a system of linear equations. You know that 2 medium drinks and a large popcorn cost $13.85, so you can write:

2x + y = 13.85

where x is the cost of a medium drink and y is the cost of a large popcorn.

You also know that 3 medium drinks and 2 large popcorns cost $23.90, so you can write:

3x + 2y = 23.9

Then , you can solve the system of equations for x and y using any method you prefer, such as elimination or substitution. For example, one way to solve the system is to multiply the first equation by 3 to eliminate y:

6x + 3y = 41.55

Then you can subtract the second equation from this equation:

6x + 3y - (3x + 2y) = 41.55 - 23.9

Simplifying this equation gives:

3x + y = 17.65

You now have two equations to solve for x and y:

3x + y = 17.65 3x + 2y = 23.9

This system of equations is equivalent to the system shown in answer A.

Answer:

A

Step-by-step explanation:

The answer is (A) because, first off you have 2 medium drinks. So that is 2x. Second you only have 1 large popcorn. So that is just y. Right now the equation is 2x + y =$13.85. The next part of the problem is the same thing. You have only 1 more medium drink this time, so it is 3x. Then you have 1 more large popcorn, so that is 2y. The final part of the equation is 3x + 2y =$23.90. Since 23.90 is just a decimal you can just get rid of the 0. Now the equation should look like this, 2x + y=$13.85

3x + 2y=$23.9

Maria wants to fill a cylindrical pool with water and uses the expression 2ℎ to determine how much water can fit into the pool. If =3.14, =10 1/2​ft, and ℎ=4 2/5​ft, approximately how many cubic feet of water did Maria determine she can fit into the pool?
Round your answer to the nearest cubic foot

Answers

The formula to calculate the volume of a cylinder is:

V = πr^2h

where π is a constant equal to 3.14, r is the radius of the cylinder (which is half of the diameter), and h is the height of the cylinder.

To use Maria's expression, we can first calculate the radius of the cylinder:

diameter = 10 1/2 ft

radius = diameter/2 = 5 1/4 ft

Next, we can substitute the values of π and h into the expression 2ℎ:

2ℎ = 2(4 2/5 ft) = 8 4/5 ft

This expression represents the height of the water in the cylinder when it is filled to capacity. To find the volume of water that can fit in the pool, we can substitute the values of π, r, and h into the formula for the volume of a cylinder:

V = πr^2h = 3.14 × (5 1/4 ft)^2 × 8 4/5 ft ≈ 581.8 ft^3

Rounding to the nearest cubic foot, the approximate volume of water that Maria determined can fit into the pool is 582 cubic feet.

A system of linear equations with more equations than unknowns is called overdetermined system. This system always be consistent. Because it may result in contradictions or inconsistencies.

An overdetermined system of linear equations cannot always be consistent, due to contradictions or inconsistencies. Since there are more equations than unknowns, there are likely to be restrictions and dependencies among the equations, and not all of them may be satisfied simultaneously.

There are 101 girls and 105 boys in Year 11 in a school. One girl is going to be chosen to be Head Girl and a different girl to be the Deputy Head Girl. One boy is going to be chosen to be Head Boy and a different boy to be the Deputy Head boy. How many different possible selections could be made?​

Answers

110,664,000 possible selections for Head Girl, Deputy Head Girl, Head Boy, and Deputy Head Boy from a group of 101 girls and 105 boys.

How to calculate different possible selections could be made?​

To find the number of possible selections that can be made, we need to multiply the number of choices available for each position.

For the Head Girl position, there are 101 girls to choose from. After one girl is selected for Head Girl, there are 100 girls remaining to choose from for the Deputy Head Girl position. So there are a total of 101 x 100 = 10,100 possible combinations of girls that can be chosen for these two positions.

Similarly, there are 105 boys to choose from for Head Boy, and 104 boys remaining to choose from for Deputy Head Boy. So there are a total of 105 x 104 = 10,920 possible combinations of boys that can be chosen for these two positions.

To find the total number of possible selections, we multiply the number of combinations for the girls by the number of combinations for the boys:

10,100 x 10,920 = 110,664,000

Therefore, there are 110,664,000 different possible selections that could be made.

simone has 20 bills, one fith of the bills are hundreds, 1/4 of ghem are fifties,1/10 of them are $20s. the rest of the bills are tens, simone has $780 altogether

Answers

we can found it by using algebra.This checks out, so we can conclude that Simone has:
4 $100 bills
5 $50 bills
2 $20 bills
9 $10 bills

And the total amount of money she has is indeed $780.Let's start by using algebra to represent the information given in the problem. Let:

x = 20 (Simone has 20 bills in total)
h = x/5 (One fifth of the bills are hundreds)
f = x/4 (One fourth of the bills are fifties)
t = x/10 (One tenth of the bills are twenties)
n = x - h - f - t (The rest of the bills are tens)
We also know that the total amount of money Simone has is $780. We can use this information to write an equation:
100h + 50f + 20t + 10n = 780

Now we can substitute the values we found for h, f, t, and n in terms of x:

100(x/5) + 50(x/4) + 20(x/10) + 10(x - x/5 - x/4 - x/10) = 780

We can see that the number of bills must be a whole number, and therefore x must be a multiple of 20. Let's try assuming that Simone has 20 bills of each denomination, which would give us:

h = x/5 = 4 (4 hundreds)
f = x/4 = 5 (5 fifties)
t = x/10 = 2 (2 twenties)
n = x - h - f - t = 9 (9 tens)
Using these values in the algebraic  equation we derived earlier, we get:
100(4) + 50(5) + 20(2) + 10(9) = 780.

Simone has 20 bills. One fifth of the bills are hundreds, 1/4 of them are fifties, 1/10 of them are $20s. The rest of the bills are tens.

find the general solution of the given higher-order differential equation. 16 d 4y dx4 16 d2y dx2 4y

Answers

The general solution of the given higher-order differential equation is y(x) = A * e^(-x/2) * cos((x/√2)) + B * e^(-x/2) * sin((x/√2)).

To find the general solution of the given higher-order differential equation, first, let's rewrite the equation in a more standard form:
16y'''' + 16y'' + 4y = 0
Now, we'll solve this fourth-order linear homogeneous differential equation using the characteristic equation method.
1. Write the characteristic equation:
16r^4 + 16r^2 + 4 = 0
2. Divide the equation by 4 to simplify:
4r^4 + 4r^2 + 1 = 0
3. Apply a substitution: let t = r^2, then the equation becomes:
4t^2 + 4t + 1 = 0
4. Solve the quadratic equation for t using the quadratic formula:
t = (-B ± √(B^2 - 4AC)) / 2A
t = (-4 ± √(4^2 - 4(4)(1))) / (2 * 4)
t = (-4 ± √(16 - 16)) / 8
t = -4/8 = -1/2
5. Substitute back r^2 for t:
r^2 = -1/2
6. Solve for r:
r = ±√(-1/2)
r = ±(1/√2)i
7. Since the roots are complex conjugates, the general solution can be written as:
y(x) = A * e^(-x/2) * cos((x/√2)) + B * e^(-x/2) * sin((x/√2))
where A and B are arbitrary constants determined by the initial conditions of the problem.

a simple random sample of 100 observations was taken from a large population. the sample mean and the standard deviation were determined to be 1,234 and 190 respectively. what is the standard error of the mean?

Answers

The standard error of the mean is approximately 19.

How the standard error of the mean is approximately 19?

The standard error of the mean (SEM) can be calculated using the following formula:

SEM = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size, and sqrt() denotes the square root.

Since the population standard deviation (σ) is not given, we can estimate it using the sample standard deviation (s) as follows:

σ ≈ s

Therefore, the formula for SEM can be rewritten as:

SEM ≈ s / sqrt(n)

Substituting the given values, we get:

SEM ≈ 190 / sqrt(100)

= 190 / 10

= 19

So the standard error of the mean is approximately 19.

The standard error of the mean measures the variability of the sample means around the population mean. It is the standard deviation of the sampling distribution of the mean, and it represents the amount of error that can be expected when using the sample mean as an estimate of the population mean.

To calculate the SEM, we need to know the population standard deviation or estimate it using the sample standard deviation. Since we only have the sample standard deviation in this case, we use it as an estimate of the population standard deviation. Then, we apply the formula for SEM and simplify it to obtain the final answer.

Answers

According to the given information we can conclude that Richard paid $123.90 for the car rental.

To solve this problem, we need to calculate the total cost of the car rental based on the daily rate and the mileage charge.

First, we can calculate the cost of the rental for two days by multiplying the daily rate by the number of days:

2 days x $34.95 per day = $69.90

Next, we need to calculate the cost of the mileage charge. To do this, we can multiply the number of miles driven by the mileage rate:

300 miles x $0.18 per mile = $54.00

Finally, we can find the total cost of the car rental by adding the cost of the rental and the cost of the mileage charge:

$69.90 + $54.00 = $123.90

Therefore, Richard paid $123.90 for the car rental.

We would need to solve for D

d = 2 [tex]\sqrt{\frac{A}{tt} } = 2 x \sqrt{\frac{16}{tt} }-around- 4.51352-or-4.51[/tex]

Thus the answer to your problem is, 4.51 or A. 4
