The average atmospheric pressure on earth is approximated as a function of altitude by the relation Patm = 101.325 (1 = 0.02256z 5.256, where Patm is the atmospheric pressure in kPa and z is the altitude in km with z = 0 at sea level. Determine the approximate atmospheric pressures at Atlanta (z = 306 m), Denver (z = 1610 m), Mexico City (z 2309 m), and the top of Mount Everest (z = 8848 m).
