Answer:

25% of the length is 7.5 (seven and five tenths) feet

Step-by-step explanation:

25% of 30

7.25 feet is 25% of length.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

The length of wall is 30 feet.

So, 25% of length

= 30 x 25/100

= 30 x 1/4

= 30/4

= 7. 25 feet

Hence, 7.25 feet is 25% of length.

let sumRadicals = a + b // 15

let differenceRadicals = b - a // 5

let productRadicals = differenceRadicals / a // 1

If the population standard deviation of a sample decreases without other changes, then the confidence interval will also decrease or become narrower.

If the population standard deviation of a sample decreases without other changes, the standard deviation of the sample mean (known as the standard error of the mean) will also decrease. This will lead to a decrease in the width of the confidence interval, meaning that the interval will become more precise and the confidence level in the estimation of the population mean will increase.

A smaller standard deviation results in a smaller standard error, which in turn leads to a narrower confidence interval and a higher level of confidence in the estimation of the population mean.

This is because the confidence interval is calculated using the standard error and the sample mean, and the standard error is a measure of the variability in the sample mean. So, if the standard deviation decreases, the variability in the sample mean will decrease, resulting in a more precise estimation of the population mean.

Answer: 112.5

Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

The phase angle by which v1(t) leads i2(t) is -42 degrees or V1 leads i2 by 42 degrees.

Given that,

v1(t) = 4sin(377t + 45°) V;

i2(t) = -0.1sin(377t + 87°)

To find the phase angle by which v1(t) leads i2(t), we need to first write the expressions for both v1(t) and i2(t) in the phasor form.

v1(t) can be expressed in the phasor form as

V1 = 4 ∠ 45°i2(t) can be expressed in the phasor form as i2 = -0.1 ∠ 87°

Let's now find the phase difference between the two using the formula:

Φ = ΦV1 - Φi2 where

ΦV1 = 45°

Φi2 = 87°

Φ = ΦV1 - Φi2

= 45° - 87°

= -42°

V1 leads i2 by 42 degrees.

Therefore, the phase angle by which v1(t) leads i2(t) is -42 degrees, or V1 leads i2 by 42 degrees.

Answer:

Step-by-step explanation:

Answer:

anything that is -3 or above like -2 or so on

Step-by-step explanation:

The reasonable domain is 0 <= t <= 8 and the reasonable range is 0 <= b <= 10

The domain

The equation of the function is:

b = 5t − 0.625t^2

Set the function to 0

5t − 0.625t^2 = 0

Divide through by 5t

1 − 0.125t = 0

This gives

0.125t = 1

Solve for t

t = 8

This means that the reasonable domain is 0 <= t <= 8

The range

The equation of the function is:

b = 5t − 0.625t^2

Differentiate the function and set to 0

5 − 1.25t = 0

Evaluate the like terms

1.25t = 5

Solve for t

t = 4

Substitute t = 4 in b = 5t − 0.625t^2

b = 5 * 4 − 0.625 * 4^2

Evaluate

b = 10

Hence, the reasonable range is 0 <= b <= 10

Answer:

350?

Step-by-step explanation:

I'm not totally sure though

The CORRECT answer is:

The distance on the arc between the two points is twice the radius of the circle.

Step-by-step explanation:

Radius times Radius = Diameter (180 times 180 = 360)

--

A whole circle would be 360°, but since it is splitting directly in half of the circle and is looking for half the distance, it would be 180°.

--

To be sure:

\(360/2=180\\2*180=360\)

--

If you was to go even further, such as distance for A to D, it would be 1/4 of 360 (1/4 of the circle) which would be 90° since half of 180 is 90. The same will go for the distance from B to D, it would also become 90°.

--

Thinking outside the "circle" (**BOX), C to D will also be 90°. You can also see it if you connect A to C, and C to D which will make it a 90° angle.

--

Overall, this kind of math is kind of like cutting pieces of pie with your friends. This math can be done easily, but can also lead to probabilities and circumference of a circle.

Answer:

y=-2/3x-7/3

Step-by-step explanation:

a parallel line has the same slope but different y intercept

so we need to solve for y=-2/3x+b

since it passes through 4,-5 we can plug it in for x and y

-5=-2/3(4)+b

-5=(-8/3)+b then add 8/3 to both sides

-5 is also -15/3

-7/3=b

The equation of the tangent line in slope-intercept form is y = 67x - 40.

To find the point on the function when x = 1, we simply substitute x = 1 into the given equation:

y = (1+2)(2(1)^2+3)^3 = 27

So the point on the function when x = 1 is (1,27).

To find the slope of the tangent line when x = 1, we take the derivative of the given function and evaluate it at x = 1:

y' = (2x^2+7x+6)(2x^2+3)^2 + 3(x+2)(4x^3+18x^2+18x)

y'(1) = (2(1)^2+7(1)+6)(2(1)^2+3)^2 + 3(1+2)(4(1)^3+18(1)^2+18(1))

= 67

So the slope of the tangent line when x = 1 is 67.

Using the point-slope form of the equation of a line, we can write the equation of the tangent line when x = 1 as:

y - 27 = 67(x - 1)

Simplifying, we get:

y = 67x - 40

So the equation of the tangent line in slope-intercept form is y = 67x - 40.

The yearly deposit needed to achieve the retirement goal is approximately $17,650.23. None of the given options match this amount, so the correct answer is not provided in the given options.

To calculate the yearly deposits needed, we can use the concept of future value of an annuity. The future value formula for an annuity is given by:

FV = P * [(1 + r)^n - 1] / r

Where:

FV = Future value of the annuity

P = Yearly deposit amount

r = Interest rate per period

n = Number of periods

In this case, the future value needed is $2 million, the interest rate is 8% (0.08), and the number of periods is 30 years. We need to solve for the yearly deposit amount (P).

Using the given formula:

2,000,000 = P * [(1 + 0.08)^30 - 1] / 0.08

Simplifying the equation:

2,000,000 = P * [1\(.08^3^0 -\) 1] / 0.08

2,000,000 = P * [10.063899 - 1] / 0.08

2,000,000 = P * 9.063899 / 0.08

Dividing both sides by 9.063899 / 0.08:

P = 2,000,000 / (9.063899 / 0.08)

P ≈ 2,000,000 / 113.298737

P ≈ 17,650.23

Therefore, the yearly deposit needed to achieve the retirement goal is approximately $17,650.23. None of the given options match this amount, so the correct answer is not provided in the given options.
