hw Certain chemotherapy dosages depend on a patient's surface area. According to the Mosteller 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 165 cm, but she is losing weight. If she loses 5 kg per month, how fast is her surface area decreasing at the instant she weighs 85 kg? dS Use implicit differentiation to determine when Kim's height is a constant 165 cm. dS dw dt dt If she loses 5 kg per month, Kim's surface area is decreasing by at the instant she weighs 85 kg. (Round to four decimal places as needed.) Ta Submit quiz Submit quiz
