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



The answer is 63.6 degrees Fahrenheit or rounded up it wpuld be 64 degrees
The area of Philip and Laura's pool is 3x^2 - 13x - 10 square feet
<h3>Area of a rectangle</h3>
Givene the dimensiion of Philip and Laura's pool as:
Length = (x - 5)
Width = (3x + 2)
Given the area expressed as:
f(x) = (x - 5)(3x + 2)feet
Taking the product will give:
f(x) = 3x^2 + 2x -15x - 10
f(x) = 3x^2 - 13x - 10
Hence the area of Philip and Laura's pool is 3x^2 - 13x - 10 square feet
