At sea level, air pressure is 30 inches of mercury. At an altitude of hh feet above the sea level, the air Pressure, P, P, in inches of mercury, is given by the function P=30e−0.0000323h. P=30e−0.0000323h. Determine the rate of change of the air pressure, in inches of mercury per feet, for a pilot of a small plane passing through an altitude of 14501450 feet. Round your answer to five decimal places.
