Answer:
Step-by-step explanation:
1. Interchange x and y. We get: x = y^2 - 5
2. Solve for y: y^2 = x + 5, so that y = ±√(x + 5)
-10x-1 = 11 -9x
+10x +10x
-1 = 11 + x
-11 -11
-12 = x
x= -12
Answer:
12.86 sq ft
Step-by-step explanation:
Find area of square and subtract out area of semi-circle; the diameter of the semi-circle equals the side of the square, which is 4 so radius is 2
A(square) = 4 x 4 = 16
A(semi-circle) = πr²/2
= 4π/2 or 2π
Area of Shaded Region = 16-3.14 which is 12.86
I believe that the correct answer C.
