Answer:

Volume of the cylinder = 36 pi units³.

Step-by-step explanation:

Given : A cylinder of radius 3 units and height 4 units.

To find : What is the volume of the cylinder below.

Solution : We have given

Radius = 3 units .

Height 4 units.

Volume of the cylinder = pi (radius)² * height.

Plugging the values of radius = 3 units , height= 4 units .

Volume of the cylinder = pi (3)² * 4.

Volume of the cylinder = pi (9) * 4.

Volume of the cylinder = 36 pi units³.

Therefore, Volume of the cylinder = 36 pi units³.

Variable y varies directly with variable x. If x = 12, then y = 3. What is the value of y

Monica [59]

Answer:

Step-by-step explanation:

To find the value of y when x = 8 we must first find the relationship between the two variables.

The statement

y varies directly with variable x is written as

y = kx

where k is the constant of proportionality

when

x = 12

y = 3

Substitute the values into the above formula and solve for k

That's

3 = 12k

Divide both sides by 12

$k = \frac{1}{4}$

So the formula for the variation is

$y = \frac{1}{4} x$

when

x = 8

$y = \frac{1}{4} \times 8$

we have the final answer as

Hope this helps you

The quantity of Sensitech laser gaming mice demanded each month is related to the unit price by the equation p = 480.03x2 + 1 (0

stich3 [128]

Answer: a) $p=480.03x^2+1$ , b) $R'(x)=1440.09x^2+1$ c) $5761.36.

Step-by-step explanation:

Since we have given that

Unit price is expressed as

$p=480.03x^2+1$

Let x be the number of units of a thousands.

So, Revenue function is given by

$R(x)=px\\\\R(x)=x(480.03x^2+1)\\\\R(x)=480.03x^3+x$

.(b) Find the marginal revenue function R'..

Marginal revenue function becomes,

$R'(x)=3\times 480.03x^2+1\\\\R'(x)=1440.09x^2+1$

$R'(2)=1440.09(2)^2+1\\\\R'(2)=5760.36+1\\\\R'(2)=5761.36$

Hence, a) $p=480.03x^2+1$ , b) $R'(x)=1440.09x^2+1$ c) $5761.36.

PLEASE HELP Word problem involving average rate of change

oee [108]

Answer:

(a): 26.1

(b): 27.9

Please see below for the steps.

Step-by-step explanation:

(a):

Use points (0,0) and (3, 78.3)

Use slope formula. The slope formula is also used to find average rate of change (just so you know).

y2-y1/x2-x1

78.3-0/3-0=78.3/3=26.1

Answer for (a) is 26.1

(b):

Use points (4, 147.6) and (9, 287.1)

Use slope formula.

y2-y1/x2-x1

287.1-147.6/9-4=139.5/5=27.9

The answer for (b) is 27.9

Hope this helps!

Please mark as brainliest if correct!

Have a great day!
