m Certain chemotherapy dosages depend on a patient's surface area. According to the Mostelier model. S = 60_' where h is the patient's height in centimeters. w is the patient's weight in kilograms. and S is the approximation to the patient's surface area in square meters. Assume that Kim's height is a constant 163 em, but she is losing weight If she loses 4 kg per month. how fast is her surface area decreasing at the instant she weighs 77 kg? dS Use implicit differentiation to determine E when Kim's height is a constant 163 cm. If she loses 4 kg per month. Kim's surface area is decreasing by [:I E at the instant she weighs 77 kg. (Round to four decimal places as needed.)
