6.6 Finding Rational Zeros
Lesson 6.6: Help for Exercise 60 on page 363
The verbal model shown below can represent the volume of the monument and the base:
Assign labels and create an algebraic model, using the formula of a rectangular solid. You are given 90 cubic feet as the total volume. Because you are also given the dimensions of the monument, x, x, 3x, and the base, x , x, 0.5, as algebraic expressions, you can substitute them into the formula for the volume of a rectangular solid. Write the algebraic model in standard form and use the rational theorem to generate a list of potential zeros for the function. Remember that negative values for x do not make sense in the context of the problem. This will help you to eliminate the number of values of x that need to be tested.
