Extracted text: A model for the surface area of a human body is given by the function S = f(w, h) = 0.1091w0.425h0.725 where w is the weight (in pounds), h is the height (in inches), and S is measured in square feet. Calculate and interpret the partial derivatives. as aw (175, 68) (a) square feet per pound O (rounded to four decimal places) This is the rate at which body surface area increases with respect to weight when an individual weighs X Ibs and has a height X in. as (b) square feet per inch (rounded to three decimal places) ah (175, 68) This is the rate at which body surface area increases with respect to height when an individual weighs X Ibs and has a height X in.
