Find the value of y.

Answer:

Answer: The volume of the pipe is 412 cubic feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder = π x radius² x height (Length in this case)

Replacing with the values given:

V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet  (rounded)

In conclusion, the volume of the pipe is 412 cubic feet

Feel free to ask for more if needed or if you did not understand something.

Answer:

V = 392.5 cubic feet

Step-by-step explanation:

[tex]v=\pi r^{2} h=\pi (2.5)^{2} (20)=\pi (6.25)(20)=125\pi[/tex]

[tex]\pi =3.14[/tex]

[tex]v=392.5cu.ft[/tex]

Answer:

A derivative is a slope function. If you want to find the slope anywhere along the function, you can.

Explanation:

Given: What is the purpose of a derivative?

A derivative is a slope function: m=f'(x=value). If you want to find the slope anywhere along the function, you can.

If you want to find a tangent line at a specific point along the function you can, using the slope and the point: y−y1=m(x−x1)

Answer:

See below

Step-by-step explanation:

A derivative is a slope function, so it allows you to find the slope anywhere along a function where it's continuous.

For example, the derivative of velocity is acceleration, which is applicable in real life.

You can also find a tangent line at a specific point by finding the slope of the function at that point and then using point-slope form [tex]y-y_1=m(x-x_1)[/tex] to get your tangent line.

Answer:

1 5/8 is 1/8 greater than 1 1/2

Step-by-step explanation:

if we take off the one from both expressions, we're left with

5/8 and 1/2.

To better compare the fractions, we can make them have equal denominators. To do this, multiply both the numerator and denominator of 1/2 by 4: (1*4)/(2*4) = 4/8.

5/8 is larger than 4/8 by 1/8, therefore, 1 5/8 is larger than 1 1/2 by 1/8.

Step-by-step explanation:

1 5/8 is greater than 1 1/2 because if you draw 1 5/8 and on the bottom 1 1/2 you will see that 1 5/8 is greater.

D. Subtract 4 from both sides

Step-by-step explanation:

When you're solving a quadratic equation you want to use the quadratic formula [tex]\frac{-b+ \sqrt[]{b^{2} -4ac } }{2a}[/tex].
To get the quadratic equation into this form, you first need to convert it into [tex]ax^{2} +bx+c=0[/tex] which means the first step would be to subtract 4 on both sides.

Answer:

[tex] I = \frac{1}{8} e^{4x^2} + C [/tex]

Step-by-step explanation:

This can be solved using substitution method. Let us work it out.

[tex] Let \: I = \int xe^{4x^2} dx[/tex]

[tex] \implies \: I = \int e^{4x^2} xdx[/tex]

[tex] Put \:4x^2 = t [/tex]

[tex] \implies 8x dx = dt [/tex]

[tex] \implies x dx = \frac{1}{8}dt [/tex]

[tex] \implies \: I = \int e^{t} \frac{1}{8}dt [/tex]

[tex] \implies \: I = \frac{1}{8} \int e^{t}dt [/tex]

[tex] \implies \: I = \frac{1}{8} e^{t} + C [/tex]

[tex] \implies \: I = \frac{1}{8} e^{4x^2} + C [/tex]

[tex] \implies \: \int xe^{4x^2} dx = \frac{1}{8} e^{4x^2} + C [/tex]

Rule for given translation (x-5,y+2)

Answer:

Given points:

Part (a)

Rotate 90° clockwise (about the origin): (x, y) → (y, -x)

Part (b)

Dilation by a scale factor → multiply the points by the scale factor

scale factor = 2

Part (c)

Reflect across the x-axis:  (x, y) → (x, -y)

Part (d)

Translate 2 up and 5 to the left:  (x, y) → (x - 5, y + 2)

The equation used to find the total mileage, m, that will make the cost, p, of renting a moving truck for one day equal at each rental company is 45 miles

Mega movers:

Fixed cost per day = $19.50

Additional cost per mileage = $0.95

p = 19.50 + 0.95m

U-move:

Fixed cost per day = $42.00

Additional cost per mileage =$0.45

p = 42.00 + 0.45m

19.50 + 0.95m = 42.00 + 0.45m

0.95m - 0.45m = 42.00 - 19.50

0.50m = 22.50

m = 22.50 / 0.50

m = 45 miles

Answer: 3.8 vitamins

Step-by-step explanation:

    First, we will find all the data values by looking at the graph.

1, 1, 3, 5, 9

    Next, we will solve for the mean. This is where we add all the data values together, and divide by the number of values.

[tex]\displaystyle \frac{1+1+3+5+9}{5}[/tex]

[tex]\displaystyle \frac{19}{5}[/tex]

3.8

         The mean is 3.8.

Answer:

3.8 vitamins

Step-by-step explanation:

Step 1:  Determine the mean of the data

The mean of the data is also known as the average of the data.  We get this by adding up all of the values and dividing it by the amount of values that we have.

In this example, we have two points on the 1 marker, one point on the 3 marker, one point on the 5 marker, and one point on the 9 marker.

We add up all of the values, 1 + 1 + 3 + 5 + 9 and we get 19.  We then divide the number of values that we have which is 5.  So we do 19/5 and we get 3.8 vitamins is the mean.
