polynomial

Question

During the first 13 sec of a jump, the number of feet that a skydiver falls in t seconds is approximated the polynomial.
11.12t^2
In 2009, 108 U.S. skydivers fell headfirst in formation from a height a height of 18,000ft. How far had they fallen 3 sec after having jumped from the plane?
The distance they had fallen after having jumped from the plane is __ ft. 

Answer 1

Are you sure that's the whole polynomial? If so, just plug in t = 3:

 

11.12(3)² = 11.12(9) = 100.08 feet
