Solve.A rocket is shot straight up in the air from the ground at a rate of 70 feet per second. The rocket is tracked by a rangefinder that is 473 feet from the launch pad. Let d represent the distance from the rocket to the rangefinder and t represent the time, in seconds, since "blastoff". Express d as a function of t.
A. d(t) = 
B. d(t) = 473 + 70t2
C. d(t) = 
D. d(t) = 4732 + (70t)2
