In a healthy person of height inches, the average pulse rate in beats per minute is modeled by the formula 596/(x^.5) for 30<x<100. Using linear approximation, the estimate for the change in pulse that corresponds to a height change from 59 inches to 60 inches is

Answer 1

beatspermin= 596/sqrtX
delta bpm=-1/2 * 596/xsqrtx= -1/2 * 596*bpm/height * dheight

deltabpm= -298*bpm*1/60=-5*bpm
