Answer:
Fred.
Started hang gliding at a height of 700 ft and descends 15 feet every seconds
Gene
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 [tex]f(x)=-15x+700[/tex]
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 [tex]\frac{565-575}{1-0} =-10[/tex] ft/s.
This means that in every seconds, Gene descends 10 feet.
