Sagot :

Given: Air pressure may be represented as a function of height above the surface of the Earth as

[tex]P=P_0e^{-0.00012h}[/tex]

Where h is the height in meters and

[tex]P_0\text{ is the air pressure at sea level.}[/tex]

Required: To find out which equation will find the height at which air pressure is 65% of the air pressure at sea level.

Explanation: We are given that air pressure is 65% of the air pressure at sea level i.e.

[tex]\begin{gathered} P=65\%\times P_0 \\ P=0.65P_0 \end{gathered}[/tex]

Now putting this value of P in the given function we get

[tex]0.65P_0=P_0e^{-0.00012h}[/tex]

This is equivalent to the expression given in option A.

Final Answer: Option A is correct.
