Answer:
7.9% reduction.
Step-by-step explanation:
Kerrin's initial weight can be calculated by 13(14)+7=189 pounds.
Three months later he weighs 12(14)+6=174 pounds.
The difference between 189 and 174 is 15 pounds.
≈.0793651 or 7.9%.

Answer:
Step-by-step explanation:
The slope of 
is:
The negative reciprocal of that slope is:
So the perpendicular line will have a slope of 
:
And now put in the point 
:
And that answer is OK, but let's also put it in 
form:
Answer: Approximately 112.86 miles in any direction away from the radio station
Step-by-step explanation: If the radio signal of the radio station can cover a circular area of 40,000 square miles, it simply means any direction away from the radio station that is within the coverage area. With the radio station as the center, we would have a radius that can reach any point within the area, and any distance beyond the radius would be out of coverage area. If the area has been given as 40000, then we have;
Area of a circle = pi x r^2
40000 = 3.14 x r^2
By cross multiplication we now have
40000/3.14 = r^2
Add the square root sign to both sides of the equation
112.8665 = r
Therefore, the farthest a person can live away from the radio station is approximately 112.86 miles
