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

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.
