Question

My If the recommended adult dosage for a drug is D (in mg), then to determine the appropriate dosage c for a child of age a years, pharmacists use the equation c = 0.04170(a + 1). Suppose the dosage for an adult is 50 mg. (a) Find the slope of the graph of c. (Round your answer to two decimal places.) What does it represent? The slope represents the change in mg of the dosage for a child for each change of 1 year in age. (b) What is the dosage for a newborn? (Round your answer to two decimal places.) mg

Explanation / Answer

c = .0417D ( a+ 1)

plugging D =50

c = .0417 (50) ( a + 1)

c = 2.085 a + 2.085

slope = 2.09

b) dosage for a newborn is 2.09 mg
