Aboat heads north across a river at a rate of 2 miles per hour. if the current is flow a boat heads north across a river at a rate of 2 miles per hour. if the current is flowing east at a rate of 5 miles per hour, find the resultant velocity of the boat. (assume that east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.)

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
