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

The answer is to 2+2 is equal to 4
Answer:
See example below.
Step-by-step explanation:
You'll need the height and radius of the cone to find the volume. Use the example below to find your solution.
Example:
The volume of the cone is found using the volume formula for a cone 
.
Substitute h=18 and r = 6.
A half sphere is a hemisphere. The volume of a hemisphere is half of 
. Substitute r=6.
However the hemisphere is half this so it is 
.
The total volume for this example is 452.6 + 678.24 = 1,130.84
