(4 points) Atmospheric pressure decreases by about 11.4% for every 1000 meters you climb. The pressure at sea level is 1013 millibars (a unit of pressure). Construct an exponential model to represent the atmospheric pressure at a given altitude in thousands of meters. Use your model to determine the atmospheric pressure at an altitude of 4650 meters. (Express your answer in millibars rounded correctly to the nearest tenth.) 1 millibars
