    Complete question is;

    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) = -16t² + 250t. Find the height at t = 4 seconds

    Answer:

    744 ft

    Step-by-step explanation:

    We are told that the height of the rocket is represented by the polynomial P(t) = -16t² + 250t

    Where t is time in seconds.

    Now, we want to Find the height at t = 4 seconds

    Thus;

    P(4) = -16(4²) + 250(4)

    P(4) = -256 + 1000

    P(4) = 744 ft
