An open-faced box is made from a square piece of paper that measures 16 inches by 16 inches. The box will be made by cutting small x by x sized squares out of each corner. What’s an equation for the volume of the box in terms of x that could be used to determine how to make the box with the biggest volume? A. V=x(16−x)2 B. V=x(16−2x)2 C. V=x(16)(16) D. V=x3
The population of South Carolina can be approximated using the formula y = 1.264e0.011x, where x is the number of years since 1900 and y is the population in millions. Use this equation to estimate the year that the population will reach 5.0 x 106 people. (Recall 1,000,000 is 1 million, so something like 5 × 106 is 5 million.) Be sure to enter in the actual year, not just the number of years since 1900.
