The graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis. which equation describes g(x)? a) g(x)=|x−4| b) g(x)=|x+4| c) g(x)=−4|x| d) g(x)=|x|−4

That would be choice C.

The graph of  4|x| is shaped like a V whose vertex is at the origin.

Every y value will be positive for y = 4|x|  as |x| is always positive  and a reflection in the x axis will make every y value negative.

its 50 miles away from the starting point

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
