-A stone is dropped from a tower that is 770 feet high. The formula $h = 770 - 16 t ^ { 2 }$ describes the stone's height above the ground, $h$, in feet, $t$ seconds after it was dropped. What is the stone's height 4 seconds after it is released?
A) $514 \mathrm { ft }$
B) $524 \mathrm { ft }$
C) $489 \mathrm { ft }$
D) $539 \mathrm { ft }$

Quizplus · Accepted Answer

Substituting $t = 4$ into the formula $h = 770 - 16t^2$ gives $h = 770 - 16(4)^2 = 770 - 256 = 514$ feet.
