Answer:
D
Step-by-step explanation:
Radius of a circle: r = 2 ft
Central angle: α = 5 π /3 = 300°
Arc Length = 2 · 2 · π · 300/360 = 2 · 2 · 3.14 · 5/6 = 10.4666 ft ≈ 10.5 ft
Answer:
C ) 10.5 ft
Answer:
y - 18 = -1.5(x - 12)
Step-by-step explanation:
A = (12, 18)
B=(1.25(12), 0.75(18)) = (15, 13.5)
Find slope: m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5
Point slope form: y - y1 = m(x - x1)
Using point A as (x1, y1)
y - 18 = -1.5(x - 12)
She should purchase 120ft of material to cover the rectangular room.
12ft x 10ft = 120ft
The correct answer is F(-2)=-23
