Answer:
9 inches
Step-by-step explanation:
Convert from feet to inches by multiplying by 12:
3*12 = 36
Multiply by the scale factor of 1/4:
36*1/4 = 9
9 inches
X/5+9=4
Subtract each side by 9
X/5=-5
Multiply each side by 5
X=-25
25 is about 3.32% of 752.

(c)

Step-by-step explanation:
(a)
Simply evaluate (a+h) in the function:

(b)
Evaluate (a) in the function:

Using the previous answers lets calculate f(a+h)-f(a)

(c) To find the rate of change of f(a+1) when a=7 we need to calculate its derivate at that point:
