Ex 2.10
3) the perimeter of a rectangle is 60m and its length is x m. show that the area of the rectangle is given by the equation a=30x-x². hence find the maximum area of the rectangle

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

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
