Question:
The pressure in pounds per square inch was measured at various altitudes of h, in kilometers (km), above Earth's surface. The results are shown in the following table.
Altitude (km) | 0 | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 |
---|---|---|---|---|---|---|---|---|---|
Pressure (lb/in2) | 14.7 | 11.91 | 9.315 | 7.64 | 6.129 | 4.637 | 3.676 | 3.193 | 2.358 |
Use exponential regression to find an exponential function for the pressure, P, at an altitude of h km. (Enter a mathematical expression. Round constants to the nearest thousandth.)
P =
Use the model to predict the atmospheric pressure (in lb/in2) at an altitude of 15 km. Round to the nearest tenth.
