Answer: 
Step-by-step explanation:
Given the following function:
You need to follow these steps in order to solve the exercise:
1. Substitute 
:
2. Now you need to apply the Quadratic formula. This is:
In this case, you can identify that:
Then, you can substitute these values into the formula:
3. Evaluating, you get:
4. You must choose the positive value. Then:
2:7 = 4:14 because each is equal to 2/7. If you simplify 4:14 by dividing by 2, it simplifies to 2:7.
Answer:
0.4*0.59=0.236
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
