MONTGOMERY COUNTY COMMUNITY COLLEGE MAT 011 Assignment 10 Name ______________________________ The algebra for the homework assignment must be done on loose leaf paper and the graphs on graph paper. 1. A deep-sea diver is taking some readings at 360 feet below the sea surface. He begins ascending at 20 feet per minute. Since the deep sea diver is below the surface, when he begins to ascend he is at - 360 feet. a. b. Graph the equation. Label your axis and use an appropriate scale. Only graph the portion that is relevant to the problem. c. What are the intercepts and what do they mean? d. 2. Write an equation for the depth of the diver in terms of time. (If you don't recognize the equation form a table.) What is the slope of the line? What does it mean? You are offered two very similar sales jobs. Company Bankrupt, pays you $30,000 Company Profitless, pays $10,000 plus 5% commission on your sales. a. while Find an equation for your salary from Bankrupt. Find an equation for your salary from Profitless. b. Graph both equations on the same set of axis. Label your axis and choose an appropriate scale. Only graph the portion that is relevant to the problem. c. Use the equations to find where the lines intersect. Label the point. Write a sentence explaining what this point means. d. Use the graph to find when Bankrupt pays more than Profitless. e. Use the graph to find when Profitless pays more then Bankrupt. f. Find the slope for both companies and write a sentence explaining what they mean in terms of the problem. g. Find the salary intercepts for both companies. Write a sentence explaining what they mean in terms of the
