Area Perform the following steps to find the maximum area of the rectangle shown in the figure.
(a) Solve for c in the equation
(b) Use the result in part (a) to write the area A as a function of x. [Hint:
(c) Use a graphing utility to graph the area function. Use the graph to approximate the dimensions of the rectangle of maximum area. Determine the required area.
(d) Use a graphing utility to graph the expression for c found in part (a). Use the graph to approximate
Use this result to describe the changes in the dimensions and position of the rectangle for

- Revenue A manufacturer finds that the revenue generated by selling x units of a certain commodity is given by the function R(x)=80x0.4x2, where the revenue R(x) is measured in dollars. What is the maximum revenue? and how many units should be manufactured to obtain this maximum?arrow_forwardMaximum Profit The profit P (in dollars) generated by selling x units of a certain commodity ¡s given by P(x)=1500+12x0.0004x2 What is the maximum profit, and how many units must be sold to generate it?arrow_forwardDrug Concentration When a drug is administered orally, it takes some time before the blood concentration reaches its maximum level. After that time, concentration levels decrease. When 500 milligrams of procainamide is administered orally, one model for a particular patient gives blood concentration C, in milligrams per liter, after t hours as C=2.65(e0.2te2t) What is the maximum blood-level concentration, and when does that level occur?arrow_forward
- Maximizing parking lot area A rectangular parking lot is being constructed for your college football stadium. If the parking lot is bordered on one side by a street and there 750 yards of fencing available for the other three sides, find the length and width of the lot that will maximize the area. What is the largest are that can be enclosed?arrow_forwardPath of a Diver The path of a diver is modeled by f(x)=49x2+249x+12 where f(x) is the height (in feet) and x is the horizontal distance (in feet) from the end of the diving board. What is the maximum height of the diver?arrow_forward
