Polynomial Optimization

You want to make a box to contain dirt and your pet earthworm. Using a 7 in by 10 in rectangle of cardboard, you cut congruent squares from the corners and fold up the sides.

Choose the equation would you use in order to do Calculus to find the maximum volume of dirt (including worm) the box can hold?

There will be fencing put in around the entire enclosure and in the middle (as pictured) to create 3 sections, what dimensions should the overall enclosure be in order to use the least amount of fence?

Which equation represents the fence amount (F) that you want to minimize?

Farmer Jo has 32 square feet of land in which to make an enclosure for bunnies, chicks, and penguins. There will be fencing put in around the entire enclosure and in the middle (as pictured) to create 3 sections, what dimensions should the overall enclosure be in order to use the least amount of fence?

• The overall enclosure should be 8 feet by 8 feet

• The overall enclosure should be 8 feet by 4 feet

• The overall enclosure should be 32 square feet

Write an expression in simplified form to represent the area of the rectangle.

Pick the correct interpretation from the given number line for V', the derivative of V.

• V has a minimum at 3

• V has a maximum at both 1 and 5

• V has a maximum at 0 and a minimum at 6

• V has a maximum at 1 and a minimum at 5

• plug in 12 and -12, resulting in a maximum

• plug in 10 and 14, resulting in a minimum

• plug in 10 and 14, resulting in a maximum

• take the derivative of the expression

A closed rectangular shipping box with square base is to be made from 120 square inches of cardboard. What dimensions should the box be for maximum volume? Choose the constraint and optimization equations that represent the problem.

Alice is managing the finances for her two startups over the past year. The profit from the first startup is represented by the equation 4x - 2x³, and the profit from the second startup is given by 5x³ - 4x + 5. Alice needs to calculate the combined annual profit from both startups.

• 3x³ + 5

• 3x³ + 8x + 5

• 3x² + 5

• 7x³ + 8x + 5
