Answer:
the answer is A.4 in
Step-by-step explanation:
Intensity=k/(distance)² where k is a constant
8000=k/2²
8000=k/4
k=32000
If distance is 11 miles, Intensity=k/11²
=32000/121
=264.46units
≈264units
Answer:

Answer:
The line is y = (1/2)x + 3
Step-by-step explanation:
We can calculate a slope. I'll use the two points (-4,1) and (-1,2.5).
Rise = (2.5-1) = 1.5
Run = (-1-(-4)) = 3
Rise/Run = Slope = (1.5/3.0) = 1/2
Find b, the y-intercept, by using point (-4,1) in the equation y = (1/2)x + b
y = (1/2)x + b
1 = (1/2)*(-4) + b
1 = -2 + b
b=3
The line is y = (1/2)x + 3
