Solve.
-A projectile is fired upward from the ground with an initial velocity of 200 feet per second. Neglecting air resistance, the height of the projectile at any time $t$ can be described by the polynomial function $P ( t ) = - 16 t ^ { 2 } +$ $200 \mathrm { t }$. Find the height of the projectile at $\mathrm { t } = 4$ seconds.
A) $644 \mathrm { ft }$
B) $544 \mathrm { ft }$
C) $736 \mathrm { ft }$
D) $800 \mathrm { ft }$

To find the height of the projectile at $t = 4$ seconds, substitute $t = 4$ into the polynomial function $P(t) = -16t^2 + 200t$. This gives $P(4) = -16(4)^2 + 200(4) = -16(16) + 800 = -256 + 800 = 544$ ft.
