The number (in thousands) of women in the work force as function of the year is shown in the figure below. Calculate and interpret the following in your case study report. Evaluate f(1983) and f(2011) using the graph. Solve f(year) = 50,000,000 using the graph. Solve f(year) = 43,000,000 using the graph. Estimate f(2014) - f(1994) using the graph. What are the natural domain and range of this function?
A popular model of carry-on luggage has a length that is 10 inches greater than its depth. Airline regulations require that the sum of the length, width, and depth cannot exceed 40 inches. These conditions, with the assumption that this sum is 40 inches, can be modeled by a function (see attached) that gives the volume of the luggage, V, in cubic inches, in terms of its depth, x, in inches. Use function V to solve; If the volume of the carry-on luggage is 2000 cubic inches, determine two possibilities for its depth. Where necessary, round to the nearest tenth of an inch.

A clock is hung on a wall so that the bottom of the clock is exactly 75 inches above the ground. The minute hand (the longest hand) is 7 inches long and touches the edge of the clock. Write a function h(t)that describes the height of the tip of the minute hand above the ground at any time, t. For ease, assume the scenario begins at noon. Recall: it takes 60 minutes for the minute hand to make a complete revolution around the clock.
