Problema Solution
Skydiving. For jumps that exceed 13 sec, the polynomial 173t – 369 can be used to approximate the distance, in feet, that a skydiver has fallen in t seconds. Approximately how far has a skydiver fallen 20 sec after having jumped from a plane?
Circumference. The circumference of a circle of radius r is given by the polynomial 2 π r, where π
is an irrational number. For an approximation ofπ, use 3.14.

Let
t = the jumps time
If t > 13 then the distance d(t) = 173t - 369
We need to find d(t) for t = 20
d(20) = 173*20 - 369 = 3091 feet
After 20 sec the skydiver has fallen 3091 feet far from the plane.
