Use the four-step procedure for solving variation problems given on page 424 to solve. \(a\) varies directly as \(b\) and inversely as the square of \(c . a=7\) when \(b=9\) and \(c=6 .\) Find \(a\) when \(b=4\) and \(c=8\).
What does it mean if two quantities vary inversely?
The perimeter of a rectangle is 50 feet. Describe the possible lengths of a side if the area of the rectangle is not to exceed 114 square feet.
Solve each inequality using a graphing utility. $$\frac{1}{x+1} \leq \frac{2}{x+4}$$
A company that manufactures running shoes has a fixed monthly cost of \(\$ 300,000 .\) It costs \(\$ 30\) to produce each pair of shoes. a. Write the cost function, \(C\), of producing \(x\) pairs of shoes. b. Write the average cost function, \(\bar{C}\), of producing \(x\) pairs of shoes. c. Findandinterpret \(\bar{C}(1000), \bar{C}(10,000),\) and \(\bar{C}(100,000)\) d. What is the horizontal asymptote for the graph of the average cost function, \(\bar{C}\) ? Describe what this represents for the company.
