Function Expressing Volume of a Cardboard Box

A cardboard box manufacturer wishes to make open boxes from rectangular pieces of cardboard with dimensions 10 in. by 17 in. by cutting equal squares from the four corners and turning up the sides. (a) Find a mathematical model expressing the volume of the box as a function of the length of the side of the square cut out. (b)

Graphing Linear Equations

Graph the equation and identify the y- intercept 1. y = x + 3 2. 6x - 3y = 9 3.Find the absolute value. Erin left a 15% tip for a meal. The toal cost the meal, including the tip, was $21.16. What was the cost of the meal before the tip was added?


What do all the points on the vertical axis of a graph have in common? For each equation, find the intercepts. Then use the intercepts to graph the equation. 4x - 3y = 12 -3x = 6y -2 -3x + 12 = 0 Please see the attached file for the fully formatted problems.

If the marginal cost of producing x units is given by 20 - 0.04x , and the fixed cost is $100, determine the cost function C(x).

Exponential and Radical Expressions Problem Set

While the radical symbol is widely used, converting to rational exponents has advantages. Explain an advantage of rational exponents over the radical sign. Include in your answer an example of an equation easier to solve as a rational exponent rather then a radical sign. Please provide sources used. 1) Solve the following e

Inverse functions
