To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the surface area and the volume of the tank:
2. Solve for in the second equation and substitute it into the first one.Then, you have:
3. Now, derivate:
4. When you solve for , you obtain:
5. Now, you must calculate :
Therefore, the dimensions are:
The sides of the base of the tank:
The height of the tank:
Answer:
A. x = -2,500.
Step-by-step explanation:
sqrt(-4x) = 100
(sqrt(-4x)^2 = (100)^2
-4x = 10,000
4x = -10,000
x = -2,500
Check your work...
sqrt(-4(-2,500))
= sqrt(4 * 2,500)
= sqrt(10,000)
= plus or minus 100
A. x = -2,500 is your answer.
Hope this helps!
Answer:
x=9/4
