If we want to find how many miles it travels in one hour, we need to find jow many seconds are in one hour because as the problem said, it's wheel rotates 5 times per second.

there are 3600 seconds in an hour, so we multiply 3600 by 5, and we get 18000.

The car travels 18000 miles in one hour.

An exercise ball contains 4000 cubic inches of air when fully inflated. Write and graph a cubic function to model this situation

juin [17]

Answer:

r = 9.8475 in

Step-by-step explanation:

We assume that the ball is spherical.

The volume of a spherical ball is:

$V = \frac{4}{3}\pi r ^ 3$

We know that:

$V = 4000in ^ 3\\4000 = \frac{4}{3}\pi r ^ 3$

Then

$r ^ 3 = \frac{3*4000}{4(\pi)}\\\\r = \sqrt[3]{\frac{3*4000}{4(\pi)}}\\\\r = 9.8475in$

Below is the graph of the cubic function
