3. a man needed money for college. he borrowed $6,000 at 14% simple interest per year. if he paid $420 interest, what was the duration of the loan?

half year

Step-by-step explanation:

The formula to find the simple interest is given by :-

, , where P is the principal amount , r is the rate of interest and t is the time in year.

Given : I=420 ; r=14%=0.14 and P =$6000

Then, we have the following equation :-

It means the duration of the loan is half year .

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
