miskamm [114]

$g(x)+-2x^5-4$

Substitute the value of x = 2 to the equation:

$g(2)=-2\cdot2^5-4=-2\cdot32-4=-64-4=-68$

Westkost [7]

A basketball is the shape of a sphere.

The volume of a sphere is given by

$V= \frac{4}{3} \pi r^3$

Given that the diameter of the basketball is 10 in., thus the radius is 10 / 2 = 5 in.

Thus, the volume of the basketball is given by

$V= \frac{4}{3} \pi(5)^3 \\ \\ = \frac{4\times125}{3} \pi=523.6\ in^3$

Therefore, The best approximate of the volume of the basketball is $5\times10^2\ in^3$
