In these problem you are asked to find a function that models a real-life situation and then use the model to answer questions about the situation. Use the guidelines on page 273 to help you. Minimizing a Sum Find two possible numbers whose sum is 100 and the sum or whose squares is a minimum.
A page that is x inches wide and y inches high contains 30 square inches of print. The top and bottom margins are each 1 inch deep and the margins on each side are 2 inches wide (see figure). (a) Show that the total area A of the page is A=2x(x+11)x4 (b) Determine the domain of the function based on the physical constraints of the problem. (c) Use a graphing utility to graph the area function and approximate the dimensions of the page that use the least amount of paper. Verify your answer numerically using the table feature of the graphing utility.
A company determines that its weekly profit from manufacturing and selling x units of a certain item is given by Px=-x3+3x2+2880x-500. Use a graphing utility to find the weekly production rate that will maximize the profit.
A triangle is formed by the coordinate axes and a line through the point (2,1), as shown in the figure. The value of y is given by y=1+2x2 Write the area A of the triangle as a function of x. Determine the domain of the function in the context of the problem. Sketch the graph of the area function. Estimate the minimum area of the triangle from the graph.
Economic Efficiency Marginal cost is the additional cost imposed by the production of one additional item. Marginal benefit is the additional benefit of producing one additional item. For a certain company, the marginal cost C, in dollars, if it is currently producing n items, is given by C(n)=5+n, and the marginal benefit B, in dollars, is given by B(n)=250.9n. Economic efficiency occurs at the production level where marginal cost and marginal benefit are the same. What production level n gives economic efficiency for this company? Round the function values to one decimal place.
Concentration of a Mixture A 1000-liter tank contains 50 liters of a 25brine solution. You add xliters of a 75brine solution to the tank. (a) Show that the concentration C, the proportion of brine to total solution, in the final mixture is C=3x+504(x+50). (b) Determine the domain of the function based on the physical constraints of the problem. (c) Sketch the graph of the concentration function. (d) As the tank is filled, what happens to the rate at which the concentration of brine is increasing? What percent does the concentration of brine appear to approach?
