Air pressure may be represented as a function of height above the surface of
the earth as shown below.
p(h) = p. e-.000121
in this function, pois air pressure at sea level, and his measured in meters.
which of the following equations will find the height at which air pressure is
85% of the air pressure at sea level?

The height is 1343.13 meters.

Step-by-step explanation:

Air pressure may be represented as a function of height h in meters above the surface of Earth as shown below :

......... (1)

In this function, P is air pressure at sea level and h is measured in meters.

Let at a height of h meters the pressure is 85% of the sea level pressure.  

Hence, from equation (1), we get

Taking ln both sides, we can write

ln 0.85 = -0.000121 h (ln e) {Since }

⇒ h = 1343.13 meters (Answer)
