Unformatted text preview: R ' t = 30 10 t where t is measured in months. How much more is the company spending on maintenance of oneyearold cars ( t = 12) than sixmonthold cars? Assuming that R (0) = 0, what is the total amount spent on maintenance over the first year? (Since R (0) = 0, the change in maintenance costs from t = 0 to t = 12 is the total amount of the cost.) Part III 10. Find the area bounded by the curves y = x 2 and y = x 6 . 11. Find the area between the curves y = ln x and y = 1 x from x = 1 e to x = e . A. Set up the integral needed to solve this. B. Use a calculator to evaluate this to the nearest hundredth. I pledge that I have neither given nor received help on this test. _______________________________________________ ________________ (signature) (date)...
