Solve the Problem $\mathrm { D } ( \mathrm { x } ) = 4700 ( 5 ) ^ { \mathrm { x } }$

Multiple Choice

Solve the problem.
-The number of dislocated electric impulses per cubic inch in a transformer increases when lightning strikes by $\mathrm { D } ( \mathrm { x } ) = 4700 ( 5 ) ^ { \mathrm { x } }$ , where $\mathrm { x }$ is the time in milliseconds of the lightning strike. Find the number of dislocated impulses at $x = 0$ and $x = 3$ .

A) $4700 ; 14,687,500$
B) $4700 ; 70,500$
C) $4700 ; 587,500$
D) 23, $500 ; 587,500$
