Question 1075826: A projectile is fired upward from the ground with a velocity of 250 feet
per second. Neglecting air resistance, the height of the projectile in feet at
any time t, in seconds, can be described by the polynomial function P(t)
= –16t^2 + 250t. Find the height at t = 4 seconds.

Substitute t= 4 into the quadratic function P(t) = -16*t^2+ 250*t

and calculate P(4). It will be your answer.
