Answer:
<h2>-5*3 -8*-5 +2</h2><h2>= -15 +40 +2</h2><h2>= 27</h2>
Area of the figure:
Af = a² + 2 a²/4 π = 2.57 a²
Area of the shaded region:
As = 2 a²/4 π = 1.57 a²
x = (1.57 · 100) / 2.57 = 61 % ≈ 60 %
Answer: B) about 60 %
Slope: (y2-y1)/(x2-x1)
(12-2)/(2-7) = 10/-5 = -2
Y = -2x + b
2 = -2(7) + b, b = 16
Y = -2x + 16
