The total yield of corn on Mr. Geller's farm from 1991 to 2010 can be modeled by the function f(x) =2x3+154x2+292x-600 (measured in kilograms) and the area of Mr. Geller's farm from 1991 to 2010 can be modeled by g(x) = 2x + 150(measured in hectares), where x is the number of years since1991. Which of the following expressions correctly describes the average yield of corn per hectare?

The total cost in thousands of dollars of manufacturing x cell phones is given by the cost function C(x) = 0.018x + 1000. Find the total cost (in thousands of dollars) of manufacturing 900 cell phones. Do not use commas or spaces in your answer. For example, if your answer is 1,536.45 thousands of dollars then input only 1536.45. Answer: K
