i think it's this i dont know i honestly forgot decimals
We are to find the value of
First we need to find the inverse of f(x) . The inverse of
is
.
Steps to find inverse of f(x) are shown below in the image.
So
=
Therefore, the correct answer is option C
The answer is 173 ft²
The area of the patio (A) is half of the area of the circle (A1) with a diameter of 21 ft:
A = A1/2
The area of the circle with radius r is:
A1 = π * r²
π = 3.14
We do not have the radius, but we know that it is a half of the diameter:
r = 21 ft / 2 = 10.5 ft
A1 = 3.14 * (10.5)² = 346.18 ft²
So, the area of the patio is:
A = A1/2
A = 346.18 ft² / 2
A = 173.09 ft² ≈ 173 ft²
