Answer:




Step-by-step explanation:
we are given

Calculation of A(4):
we can plug x=4

Since, this curve is below x-axis
so, the value of integral must be negative
and it is quarter of circle
so, we can find area of quarter circle
radius =4


Calculation of A(8):
we can plug x=8

we can break into two parts

now, we can find area and then combine them


Calculation of A(12):
we can plug x=12

we can break into two parts

now, we can find area and then combine them


Calculation of A(14):
we can plug x=14

we can break into two parts

now, we can find area and then combine them



Answer: What do I solve for?
Step-by-step explanation:
Do I need to solve for the slope, equation, x-int, etc?
Well the shortest length would be 16 because you would have to divide 80 by 5, so it would be greater than or equal to 16. Is that the whole question or is there more to it?
