Answer:
f(x) = 5(4)^x is the correct answer
Step-by-step explanation:
The diameter is . . .
d = 2r
d = 2 × 5inch
d = 10 inch
The radius is . . .
r = 5 inch
The circumference is . . .
C = πd
C = 3,14 × 10 inch
C = 31,4 inch
f(3) means value of y when x = 3
So, the answer is 2
Set up the equation 64.8 = .36x
Divide by .36 on both sides.
You get 180 = x.
36% of 180 is 64.8
Multiply .36 by 180 to double check.
Hope this helps
