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

beatspermin= 596/sqrtX
delta bpm=1/2 * 596/xsqrtx= 1/2 * 596*bpm/height * dheight
deltabpm= 298*bpm*1/60=5*bpm
