Answer:
a² = b² -w² +2wx
Step-by-step explanation:
The algebra is pretty straightforward. Expand the expression in parentheses and add x².
b² -(w -x)² = e² = a² -x²
b² -(w² -2wx +x²) = a² -x² . . . . . expand the square
b² -w² +2wx -x² = a² -x² . . . . . . distribute the minus sign
b² -w² +2wx = a² . . . . . . . . . . . . add x²

Answer:
D
Step-by-step explanation:
The equation of the circle is (x-x0)^2 + (y-y0)^2 = r^2, where (x0,y0) is the center of the circle. Radius is the distance from any point to the center. Using distance formula you get r = 3.
Answer: A
5.64-4.44 = 1.20
6.84-5.64 = 1.20
8.04-6.04 = 1.20
Each additional two hours adds $1.20 to the rental, so a slope of $0.60 per hour. That's the incremental cost per hour.
Two hours costs $4.44 so zero hours costs 4.44-1.20=$3.24. That's the y intercept, representing a fixed fee for every rental.
