Solve the Problem $\mathrm { d } ( \mathrm { t } ) = 450 + 62 \mathrm { t } ^ { 2 }$

question 205

Multiple Choice

Solve the problem.
-A rocket is shot straight up in the air from the ground at a rate of 62 feet per second. The rocket is tracked by a range finder that is 450 feet from the launch pad. Let d represent the distance from the rocket to the range finder
And t represent the time, in seconds, since "blastoff". Express d as a function of t.

• A) \(\mathrm { d } ( \mathrm { t } ) = 450 + 62 \mathrm { t } ^ { 2 }\)
• B) \(d ( t ) = 450 ^ { 2 } + ( 62 t ) ^ { 2 }\)
• C) \(d ( t ) = \sqrt { 62 ^ { 2 } + ( 450 t ) ^ { 2 } }\)
• D) \(d ( t ) = \sqrt { 450 ^ { 2 } + ( 62 t ) ^ { 2 } }\)
