125/12.5
Since we can find that the graphs Y value is by a factor of 2 looking at the graph we can find
f(3)=8
Answer: x = 10
Step-by-step explanation:
The diameter of the new rubber ball, to the nearest foot, must be D = 4.0 ft (in the case of the maximum cost).
<h3>
How to find the diameter of the ball?</h3>
Remember that for a sphere of diameter D, the surface area is:
A = 4*pi*(D/2)^2
In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:
$0.02*A = $1
A = $1/$0.02 = 50
So the surface of the ball must be 50 square feet.
Then we solve:
50ft^2 = 4*3.14*(D/2)^2
D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft

I only know number one here you goSolution
Conversion for Km to Miles
1km = 0.621 miles
Conversion Hours to minutes
1 hr = 60 mins
solve
140 (0.621 miles / 60 mins )
= 140 (0.01035 miles/min)
= 1.449 miles/min
