Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = V(- 2, 2) and (x₂, y₂ ) = W(- 4, - 2)
VW =

The volume of a cylinder is PiR^2H.
We have the radius and height, so we can answer this.
Pi = 3.14
R = 11
H = 18
3.14 x 11^2 x 18.
Your answer is 6838.92 inches.
Answer:

Step-by-step explanation:
We have been given that

We can use the formula for difference of cubes to simplify the function f(x)
difference of cubes - 

And g(x) can be written as

Thus, we have

On cancelling the common factors, we get

"y varies directly with square of x"
y = kx²
where "k" is the constant of variation you need to solve for first.
when y = 100 ; x = 5
100 = k(5)²
100 = 25k
100/25 = k
4 = k
Now you can solve for y when x = 9
y = 4(9)²
y = 4(81)
y = 324
