How would you solve a question asking for a value that exponentially decreases? I know I am supposed to use ab^x as a formula, and I am given two data points....?
the pressure of the air in the earths atmosphere decreases exponentially with the altitude above the surface of the earth. the pressure at earth's surface (sea level) is about 14.7 pounds per square inch (psi) and the pressure at 200 feet is approx. 13.5 psi.
1) write the particular equation expressing pressure in terms of altitude.
2) Predict the pressure at an altitude of 7500 feet
