1hw 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 View by Day 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 161 cm, but she is losing weight If she loses 3 kg per month, how fast is her surface area decreasing at the instant she weighs 71 kg? dS Use implicit differentiation to determine dt when Kim's height is a constant 161 cm. ds dw dt dt If she loses 3 kg per month, Kim's surface area is decreasing by at the instant she weighs 71 kg (Round to four decimal places as needed.) m2 kg m2 / month cm / month kg / month cm Next
