Question

Sorry to be a bother today, but the following question is giving me a heck of a time. It is my last attempt so I just can't screw it up again. It goes as follows:

If the temperature is constant, then the atmospheric pressure P (in pounds per square inch) varies with the altitude above sea level h in accordance with the law P = p0e−kh where
p0 is the atmospheric pressure at sea level and k is a constant. If the atmospheric pressure is 14.7 lb/in.2 at sea level and 13 lb/in.2 at 4000 ft, find the atmospheric pressure at an altitude of 13,000 ft. (Round two decimal places.) My ans: 14.7lbs

Answer 1

is the e raised to -kh?

Answer 2

\[P=p_0e ^{-kh}\]

Answer 3

is this correct?

Answer 4

@bnidt ^^^^ Please answer question.
