Plug the -1 in the x values
3(-1)-5
-3-5
= -8
5i square root 2
————————-
Just use derivatives:
f'(x)= .48x-.96 = 0, x = 2, since the coeff of x^2 is +, this is a minimum
x=0 1989, so x = 2 is 1991! :)

Answer:
The radius of sphere with volume 4500 cubic inches is 10.24 inches.
Step-by-step explanation:
Let V be the volume of the sphere
Given
Volume of sphere = V = 4500 cubic inches
Let r be the radius of the sphere
The volume of the sphere is given by the formula

Putting the known values

Taking cube root on both sides
![\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%20%3D%20%5Csqrt%5B3%5D%7B1073.8636%7D%20%5C%5Cr%20%3D%2010.2403)
Rounding off to nearest hundredth
The radius is: 10.24 inches.
Hence,
The radius of sphere with volume 4500 cubic inches is 10.24 inches.
