Answer:
y=-3x+31
Step-by-step explanation:
y-y1=m(x-x1)
y-4=-3(x-9)
y-4=-3x+27
y=-3x+27+4
y=-3x+31
Answer:
16
Step-by-step explanation:
2x+3 = 11
2x= 8
x = 4
4(x) = 4(4) = 16
Answer:
Area of model pond = 45.6 inch² (Approx.)
Step-by-step explanation:
Given:
Circumference of circular pond = 24 inches
Find:
Area of model pond
Computation:
Circumference of circle = 2πr
Circumference of circular pond = 2πr
24 = 2[22/7][r]
Radius r = [24 x 7] / [2 x 22]
Radius r = 3.81 inch (Approx.)
Area of circle = πr²
Area of model pond = πr²
Area of model pond = (22/7)(3.81)²
Area of model pond = [3.1428][14.5161]
Area of model pond = 45.6 inch² (Approx.)
