Arectangle of perimeter 100 units has the dimensions shown. its area is given by the function a = w(50 - w). what is the greatest area such a rectangle can have? the rectangle shown has 50-w on the top and bottom. and a w on its left side and right side.

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

a.)the line for function b is steeper

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
