AIR MATH

Math Question

Air pressure may be represented as a function of height above the surface of the Earth as shown below.
\[
P(h)=P_{0} e^{-.00012 h}
\]
In this function, \( P_{0} \) is air pressure at sea level, and \( h \) is measured in meters. Which of the following equations will find the height at which air pressure is \( 65 \% \) of the air pressure at sea level?
A. \( h=.65 e^{-.00012} \)
B. \( P_{0}=.65 P_{0} e^{-.00012 h} \)
c. \( .65 P_{0}=P_{0} e^{-.00012 h} \)
D. \( .65=h \cdot e^{-.00012} \)
