Answer:

<u>Fred.</u>

Started hang gliding at a height of 700 ft and descends 15 feet every seconds

<u>Gene</u>

Started hang gliding at a height of 575 ft and descends 10 feet every seconds

Step-by-step explanation:

The function that models Fred's hang gliding is f(x)=-15x+700

The initial value is 700 feet. This Fred was 700 feet above see level before he starts descending.

The rate of descent is -15 ft/s. This means Fred descends 15 feet in one second.

From the table the initial height is 575 ft. This means Gene was 575 feet above sea-level at the beginning of the hang gliding.

The rate of descent is \frac{565-575}{1-0} =-10 ft/s.

This means that in every seconds, Gene descends 10 feet.
