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



I think your answer would be C.
Answer:
A. x = 3/k.
Step-by-step explanation:
5kx + 6 = 7kx
5kx - 5kx + 6 = 7kx - 5kx
6 = 2kx
x = 6 / 2k
x = 3/k.
Answer:
