Step-by-step explanation:

if it is between 0 and pi/2 (90°), or between 3pi/2 (270°) and 2pi (360°).

for angle = 0, cos = 1. therefore, positive.

0 <= 5pi/12 <= pi/2. therefore, positive.

pi/2 <= 5pi/6 <= pi. therefore, negative.

pi/2 <= 3pi/4 <= pi. therefore, negative.

3pi/2 <= 5pi/3 <= 2pi. therefore, positive.

you do know how to compare fractions, right ?

you need to bring then to the same denominator by multiplying numerator and denominator by the same factor.

e.g. comparing 5pi/12 with pi/2.

to bring them both to .../12, we have to multiply pi/2 by 6/6.

so, we are comparing 5pi/12 and 6pi/12.

and we see, 5pi/12 is smaller.

the others work the same way.

3pi/6 <= 5pi/6 <= 6pi/6

2pi/4 <= 3pi/4 <= 4pi/4

9pi/6 <= 10pi/6 <= 12pi/6

now you see it clearly.

the particular solution to the differential equation. we use the positive sign: [tex]y = -1 + e^(1/2 x^2 + x - 5.605)[/tex]

To find the particular solution to the differential equation {dy}/{dx} = (x+1) (y+1) with the initial condition y(4) = 3, we can use separation of variables and integration.

First, we can rewrite the equation as:

[tex]{1}/{(y+1)} dy = (x+1) dx[/tex]

Next, we can integrate both sides:

[tex]∫ {1}/{(y+1)} dy = ∫ (x+1) dx[/tex]

[tex]ln|y+1| = 1/2 x^2 + x + C[/tex]

where C is the constant of integration.

To determine the value of C, we can use the initial condition y(4) = 3:

[tex]ln|3+1| = 1/2 (4)^2 + 4 + C[/tex]

[tex]ln|4| = 10 + C[/tex]

[tex]C = ln|4| - 10 = -5.605[/tex]

Therefore, the particular solution to the differential equation with the initial condition y(4) = 3 is:

[tex]ln|y+1| = 1/2 x^2 + x - 5.605[/tex]

Solving for y:

[tex]|y+1| = e^(1/2 x^2 + x - 5.605)[/tex]

[tex]y+1 = \pm e^(1/2 x^2 + x - 5.605)[/tex]

[tex]y = -1 \pm e^(1/2 x^2 + x - 5.605)[/tex]

Since [tex]y(4) = 3[/tex], we can determine which sign to use:

[tex]3 = -1 + e^(1/2 (4)^2 + 4 - 5.605)[/tex]

[tex]3 = -1 + e^(7.395)[/tex]

[tex]4 = e^(7.395)[/tex]

Therefore, we use the positive sign: [tex]y = -1 + e^(1/2 x^2 + x - 5.605)[/tex]

Answer:

This is reflected in the data as the number of bacteria doubles every two hours, which is a characteristic of exponential growth.

Data that changes or grows at an exponential rate over time is referred to as exponential data. This indicates that the data changes quickly, either increasing or decreasing, and that the pace of change quickens over time. Exponential data frequently consists of numbers that rise steadily over time, with the rate of rise accelerating over time.

a.) exponential function would be the ideal option to model this data. An exponential curve is produced as the quantity of bacteria multiplies at an ever-increasingly rapid rate.

b. One way to determine which function is the best choice is to examine the rate of change of the data. In this case, we may calculate the average rate of change for each time period and see if it is constant. If the rate of change is constant, the data can be represented by a linear function. However, if the rate of change increases or decreases, an exponential or quadratic function might be a better fit.

From 0 to 2 hours: (25-10)/(2-0) = 7.5

From 2 to 4 hours: (50-25)/(4-2) = 12.5

From 4 to 6 hours: (100-50)/(6-4) = 25

c. The distance travelled by an automobile at a constant pace is an illustration of data that would be best characterised by a linear function. Imagine a car driving for four hours at a speed of 60 mph. Below is a list of the distance covered each hour:

After 1 hour: 60 miles

After 2 hours: 120 miles

After 3 hours: 180 miles

After 4 hours: 240 miles

In this case, the distance traveled is directly proportional to the time, so a linear function would be the best fit.

c. The point estimate of the difference between the two population means is:

9.2 - 7.17 = 2.03

d. To calculate the 90% confidence interval estimate of the difference between the two population means, we need to first calculate the standard error of the difference between the sample means:

s.e.(difference between sample means) = √[(s1²/n1) + (s2²/n2)]

= √[(3.29²/5) + (3.65²/6)]

= √[2.60]

≈ 1.61

Next, we can use the t-distribution with degrees of freedom equal to the smaller of n1-1 and n2-1 (in this case, 4) and a 90% confidence level to find the critical value, t*:

t* = 1.533 (from t-distribution table or calculator)

Finally, we can construct the confidence interval estimate:

9.2 - 7.17 ± (t* * s.e.(difference between sample means))

= 2.03 ± (1.533 * 1.61)

= 2.03 ± 2.47

Describe equation?

A mathematical equation is a formula that uses the equals symbol (=) to denote the equality of two expressions.

A formula would be 3x - 5 = 16,

for instance. We may determine the value of the variable x by solving this equation: x = 73.

The slope-intercept representation of the equation can be used to determine the equation of a line running through the points (x1, y1) and (x2, y2):

y - y1 = m(x - x1) (x - x1)

where m is the line's slope. The following formula can be used to determine the line's slope:

m = (y2 - y1) / (x2 - x1) (x2 - x1)

Now put the x and y value in this:

slope of the line using the points (1, 5) and (3, 11):

m = (11 - 5) / (3 - 1) = 6 / 2 = 3

We can use the slope of the line to determine the equation of the line now that we know it:

y - y1 = m(x - x1) (x - x1)

y - 5 = 3(x - 1) (x - 1)

y - 5 = 3x - 3 = 3x + 2

In light of this, the equation for the line connecting points (1, 5) and (3, 11) is y=3x+2

To determine the value of y for x = 7, we can utilize the equation of the line we discovered earlier:

y = 3x + 2

y = 3(7) + 2

y = 21 + 2

y = **23**

Standard form for the equation of a circle is:

Convert the given equation into standard form:

Its center is ( 1, 0) and radius is r = 3.

Let's verify the statements:

Answer:

See below

Step-by-step explanation:

To find:-

Answer:-

The given equation of the circle is ,

[tex]\longrightarrow x^2+y^2-2x-8 = 0 \\[/tex]

For finding the correct statements , we need to convert this equation into standard form for a circle.

The standard equation of circle is given by,

[tex]\boxed{\begin{tabular}{c}\textbf{\underline{ \red{Standard\ equation\ of \ circle }}} \\ \\ \text{ The standard equation of a circle is given by:-} \\\\ \longrightarrow \underline{\underline{ (x-h)^2+(y-k)^2 = r {}^{2}}} \\\\ \text{where} , \\\\ \bullet\text{ (h,k) is the centre of the circle.}\\\\\bullet\text{ "r" is the radius of the circle. }\\\end{tabular}}[/tex]

Now for that we need to complete the square for "x" . This can be done by ,

Rearrange the terms,

[tex]\longrightarrow x^2-2x + y^2-8 = 0 \\[/tex]

Add and subtract 1² .

[tex]\longrightarrow ( x^2 -2x +1^2 ) - 1^2 + y^2-8=0 \\[/tex]

Simplify,

[tex]\longrightarrow (x^2-2(1)x+1^2) - 1-8 + y^2=0 \\[/tex]

Notice that the terms inside the small brackets are in the form of a² - 2ab + b² , which is the whole square of (a-b) . So we can write it as,

[tex]\longrightarrow (x-1)^2 +y^2 - 9 = 0 \\[/tex]

Add 9 on both the sides ,

[tex]\longrightarrow (x-1)^2 + y^2 = 9\\[/tex]

This can be written as,

[tex]\longrightarrow \underline{\underline{ \boldsymbol{(x-1)^2+(y-0)^2 = 3^2}}} \\[/tex]

On comparing it to the standard form, we have;

[tex]\longrightarrow\boxed{ \text{Center = (1,0) }} \\[/tex]

[tex]\longrightarrow\boxed{ \text{ Radius = 3 \ units}} \\[/tex]

Let's check the given statements ,

Statement 1: The radius of the circle is 3 units.

Statement 2: The centre of the circle lies on the x-axis.

Statement 3: The statement of the circle lies on the y-axis.

Statement 4: The standard equation of the circle is (x-1)²+y² = 3

Statement 5: The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{h}[/tex] (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

here h = 8.2 , b₁ = 9 , b₂ = 2.4

then

A = [tex]\frac{1}{2}[/tex] × 8.2 × (9 + 2.4) = 4.1 × 11.4 = 46.74 mi²

Answer: it's 1

Step-by-step explanation:

The x in the numerator determines that the x is in absolute value, meaning only positive integers.

That wouldn't matter anyway, because since any value of x would have to be greater than 0 (meaning only positive values), and both x's are the same x, the equation would have to equal one.

For example, you could plug in 2 to both x's. 2/2 is 1.

Or you could plug in 289 to both x's, in which 289/289 is 1.

No matter what number, as long as it's positive, will be 1.

The statement that is true about rhombus is d. some rhombuses have four right angles.

A rhombus is a parallelogram with equal-length sides, though the angles at the opposing ends need not be equal, nor must the sides be parallel. If a rhombus is also a cube, it can have four right angles. It can be viewed as an equal-sided trapezoid as well.

A parallelogram has two sets of parallel sides, whereas a trapezoid only has one pair of parallel sides. Therefore, it is untrue that a trapezoid has two sets of parallel edges. Not all rectangles are squares, but they are all quadrilaterals with four right angles. A unique variety of parallelogram called a square has equal-length edges. Therefore, it is untrue to say that all circles are squares.

To be 95% confident within a 4% margin of error, the programmer must survey at least 601 computers.

To estimate the percentage of computers that use a new operating system with a 95% confidence level and a 4% margin of error, you must first determine the required sample size. Here's a step-by-step explanation:
Identify the confidence level and margin of error: In this case, the confidence level is 95% and the margin of error is 4%.
Determine the standard value (Z-score) for the desired confidence level: For a 95% confidence level, the Z-score is 1.96. This value can be found using a Z-score table or an online calculator.
Use the formula for sample size calculation:
  n = (Z^2 * p * (1-p)) / E^2
  Where n is the required sample size, Z is the Z-score, p is the estimated proportion of computers using the new operating system, and E is the margin of error.
Since we do not have an estimate for the proportion (p), we will assume the worst-case scenario (p=0.5) to ensure the largest possible sample size:
  n = (1.96^2 * 0.5 * 0.5) / 0.04^2
Calculate the sample size:
  n ≈ (3.8416 * 0.25) / 0.0016
  n ≈ 0.9604 / 0.0016
  n ≈ 600.25

Step-by-step explanation:

Answer:

13 meters.

Step-by-step explanation:

We can use the formula for the volume of a rectangular prism, which is:

Volume = length x width x height

We are given that the base area (length x width) of the prism is 54 m², so we can write:

length x width = 54 m²

We are also given that the volume of the prism is 702 m³, so we can write:

Volume = length x width x height = 702 m³

We want to find the height of the prism, so we can rearrange the formula for the volume to solve for height:

height = Volume / (length x width)

Substituting the given values, we get:

height = 702 m³ / 54 m²

Simplifying this expression, we can divide both the numerator and the denominator by the greatest common factor of 54 and 702, which is 18:

height = (702/18) m / (54/18) m = 39 m / 3 m

height = 13 meters

Therefore, the height of the rectangular prism is 13 meters.

The sample's standard deviation is equal to 12. Thus, choice B is the right choice.

The variance of a sample of 144 observations equals 576.

Variance S² = 144

The standard deviation is a measure of how spread out a set of data is. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean.

The standard deviation can be used to measure the amount of variation or dispersion of a set of data values from the mean.

Standard Deviation = √Variance

Standard Deviation = √144

1.143 x 10⁷ ft, or approximately 11.43 million feet is the length of the river.

To find the length of the river, we need to use the Pythagorean theorem, which states that the square of the length of the hypotenuse (the diagonal line connecting the two endpoints of a right triangle) is equal to the sum of the squares of the lengths of the other two sides.

Let's call the length of the southward flowing part of the river "a" and the length of the southeastward flowing part of the river "b". Then we have:

a = 1.1 x 10⁷ ft

b = 3.2 x 10⁶ ft

The length of the river is given by the hypotenuse of a right triangle with sides a and b. Therefore, we can calculate the length of the river, c, as follows:

c² = a² + b²

c² = (1.1 x 10⁷ ft)² + (3.2 x 10⁶ ft)²

c² = 1.21 x 10¹⁴ ft² + 1.024 x 10¹³ ft²

c² = 1.3104 x 10¹⁴ ft²

c = √(1.3104 x 10¹⁴ ft²)

c = 1.143 x 10⁷ ft

Therefore, the length of the river is 1.143 x 10⁷ ft, or approximately 11.43 million feet

If ∠1 and ∠2 are vertical angles and m∠22 = 180°, then m∠1 = 90°

Vertical angles are pairs of angles that are opposite to each other when two lines intersect. Vertical angles are always equal in measure. Therefore, if ∠1 and ∠2 are vertical angles, then:

∠1 = ∠2

We are also given that m∠22 has a measure of 180°. Since ∠1 and ∠2 are vertical angles, they form a straight line, and their measures add up to 180°. Therefore:

∠1 + ∠2 = 180°

Since ∠1  = ∠2, we can substitute ∠1 for ∠2 in the above equation:

∠1 + ∠1 = 180°

Simplifying the equation, we get:

2∠1 = 180°

Option D is the correct option i.e., 2.5 hours. Timing is everything when it comes to dining before a fight. Athletes must ingest enough calories to power their efforts without developing gastrointestinal pain or bloating while competing. Typically, a substantial dinner should be eaten two to three hours prior to the game. 

The body needs time to process and assimilate nutrients, which is the cause of this. A big dinner requires the body to divert a lot of blood flow to the digestive system, which can have an impact on an athlete's performance. Athletes' performance can be hampered by sluggishness, gastrointestinal pain, or even vomiting brought on by eating too close to a competition.

In general, it is recommended that athletes experiment with different meal timings and types of food during their training to determine what works best for their individual needs.

They should also consider the length of the event and the intensity of their activity to determine the amount and timing of their meals. A registered dietitian or sports nutritionist can help athletes create a personalized nutrition plan to optimize their performance.

To find the total percentage decrease, we first need to find the new values of the stocks in Company A and Company B after the decrease.

The new value of the stock in Company A is: $5800 - (1% \times $5800) = $5742

The new value of the stock in Company B is: $7470 - (20% \times $7470) = $5976

To find the total value after the decrease, we add these two values: $5742 + $5976 = $11718

To find the percentage decrease from the original total value ($5800 + $7470 = $13270) to the new total value ($11718), we use the formula:

percentage decrease = [(original value - new value) / original value] x 100%

percentage decrease = [($13270 - $11718) / $13270] x 100%

percentage decrease = 11.7%

Therefore, the total percentage decrease in the investor's stock account is 11.7%.

Answer:

To find A+3B, we need to first find A and B. A = 1 + r + 7r^2 B = 1 - r^2 Now we can substitute these expressions into A+3B: A+3B = (1 + r + 7r^2) + 3(1 - r^2) Simplifying this expression, we get: A+3B = 1 + r + 7r^2 + 3 - 3r^2 A+3B = 4 + r + 4r^2 So the expression that equals A+3B in standard form is 4 + r + 4r^2.
