Researchers have found that the risk of coronary heart disease rises as blood cholesterol increases. This risk may be approximated by the function R(c) = 3.189(1.006)C, 100 3 cs 300, where R is the risk in terms of coronary heart disease incidence per 1000 per year, and c is the cholesterol in mg/dL. Suppose a person's cholesterol is 181 mg/dL and going up at a rate of 15 mgldL per year. At what rate is the person's risk of coronary heart disease going up? ~@ The person's risk of coronary heart disease is going up at the rate of 0.056' coronary heart disease incidence per 1000 per year per mg/dL of cholesterol. (Round to three decimal places as needed.) \fThe field metabolic rate (FMR), or the total energy expenditure per day in excess of growth. can be calculated for pronghorn fawns using Nagy's formula, F(x) = 0.774 + 0.72? log x, where x is the mass (in grams) of the fawn and F(x) is the energy expenditure (in kJ/day). a. Determine the total energy expenditure per day in excess of growth for a pronghorn fawn that weighs 21,000 g. b. Find F'(2'l,000) and interpret the results. c. Graph the function on [5000,30000] by [3.5]. E} a. The total energy expenditure per day in excess of growth for a pronghom fawn with a mass of 21,000 g is 3.9' kJ ' day' (Type an integer or decimal rounded to the nearest tenth as needed.) b. Determine F'(x). ' 0.727 \"'0: m (Type an exact answer.) Find F'(21,000) and interpret the results. V F'(21,000) = 1.5x105 ; when a fawn is 21 kg in mass, the rate of change of energy expenditure of the fawn is 'kJ _5 _ about 1.5x10 day per gram. (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to one decimal place as needed.) c. Graph F(x) on [5000,30000] by [3,5]. Choose the correct graph below. O D. X B. *C. O A. +
