What is the side length of a cube with a volume of 64 mm3? Cube V = s3 1. Substitute the value into the formula: 64 = s3

Mumz [18]

We have been given that the volume of cube is 64 cubic mm. We are asked to find the side length of the cube.

We will use volume of cube formula to solve our given problem.

$V=s^3$ , where

V = Volume of cube,

s = Side length of cube.

Upon substituting the given volume in above formula, we will get:

$64=s^3$

Now we will take cube-root on both sides of equation.

$\sqrt[3]{64}=\sqrt[3]{s^3}$

$\sqrt[3]{4^3}=\sqrt[3]{s^3}$

Using rule $\sqrt[n]{a^n}=a$ , we will get:

$4=s$

Therefore, the side length of the cube is 4 mm.

Profit, P(r), is the difference between revenue, R(r), and cost, C(r), so P(r) = R(r) - C(r) Which expression represents P(r), i

GuDViN [60]

The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

<h3>What is an equation? </h3>

An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

Profit is the difference between revenue and cost. Given that:

R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3

P(r) = R(r) - C(r)

P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4

The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4
