Chapter 3.2 Problem 99

Question

CONSTRUCTION A roofing contractor is fabricating gutters from 12-inch aluminum sheeting. The contractor plans to use an aluminum siding folding press to create the gutter by creasing equal lengths for the sidewalls (see figure). (a) Let represent the height of the sidewall of the gutter. Write a function that represents the cross-sectional area of the gutter. (b) The length of the aluminum sheeting is 16 feet. Write a function that represents the volume of one run of gutter in terms of (c) Determine the domain of the function in part (b). (d) Use a graphing utility to create a table that shows the sidewall heights and the corresponding volumes Use the table to estimate the dimensions that will produce a maximum volume. (e) Use a graphing utility to graph Use the graph to estimate the value of for which is a maximum. Compare your result with that of part (d). (f) Would the value of change if the aluminum sheeting were of different lengths? Explain.

Solution

Step 1 of 3)

The first step in solving 3.2 problem number 99 trying to solve the problem we have to refer to the textbook question: CONSTRUCTION A roofing contractor is fabricating gutters from 12-inch aluminum sheeting. The contractor plans to use an aluminum siding folding press to create the gutter by creasing equal lengths for the sidewalls (see figure). (a) Let represent the height of the sidewall of the gutter. Write a function that represents the cross-sectional area of the gutter. (b) The length of the aluminum sheeting is 16 feet. Write a function that represents the volume of one run of gutter in terms of (c) Determine the domain of the function in part (b). (d) Use a graphing utility to create a table that shows the sidewall heights and the corresponding volumes Use the table to estimate the dimensions that will produce a maximum volume. (e) Use a graphing utility to graph Use the graph to estimate the value of for which is a maximum. Compare your result with that of part (d). (f) Would the value of change if the aluminum sheeting were of different lengths? Explain.
From the textbook chapter POLYNOMIAL FUNCTIONS OF HIGHER DEGREE you will find a few key concepts needed to solve this.
