The radius of a cone is increasing at a constant rate of 7 meters per minute, and the volume is decreasing at a rate of 236 cubic meters per minute. At the instant when the radius of the cone is 99 meters and the volume is 180 cubic meters, what is the rate of change of the height? The volume of a cone can be found with the equation V=\frac{1}{3}\pi r^2 h. V= 3 1 πr 2 h. Round your answer to three decimal places.

The rate of change of the height is 0.021 meters per minute

Step-by-step explanation:

From the formula

Differentiate the equation with respect to time t, such that

To differentiate the product,

Let r² = u, so that

Then, using product rule

Since

Then,

Using the Chain's rule

∴

Then,

Now,

From the question

At the instant when

and

We will determine the value of h, using

Now, Putting the parameters into the equation

Hence, the rate of change of the height is 0.021 meters per minute.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
