Answer:

Step-by-step explanation:
Given:
Rate of change of radius of cylinder:

(This is increasing rate so positive)
Rate of change of height of cylinder:

(This is decreasing rate so negative)
To find:
Rate of change of volume when r = 20 inches and h = 16 inches.
Solution:
First of all, let us have a look at the formula for Volume:

Differentiating it w.r.to 't':

Let us have a look at the formula:


Applying the two formula for the above differentiation:

Now, putting the values:

So, the answer is: 
I believe you are referring to exponents that have a multiple of three. If so any number * three is a valid exponent in your case.
Answer:

Step-by-step explanation:
Take out 4:
4(x^2-8x)-12
=4(x^2-8x+16-16)-12
=4(x^2-8x+16)-64-12
=4(x^2-4)^2 - 76
=
