Air pressure may be represented as a function of height (in meters) above the
surface of the earth, as shown below.
p(h) = p.
-0.00012h
in this function, pois the air pressure at the surface of the earth, and his the
height above the surface of the earth, measured in meters. at what height will
the air pressure equal 50% of the air pressure at the surface of the earth?
