Certain chemotherapy dosages depend on a patient's surface area. According to the Gehan and George model, S=0.02235h0.42246 0.51456, where h is the patient's height in centimeters, w is his or her weight in kilograms, and S is the approximation to his or her surface area in square meters. Joanne is 150 cm tall and weighs 50 kg. Use a differential to estimate how much her surface area changes after her weight decreases by 2 kg. Joanne's surface area changes by approximately (Round to five decimal places as needed.)
