The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is c
jonny [76]

Answer:

P = 101.5 e^{-0.00015h}

Step-by-step explanation:

dP/dh = kP

dP/P = k dh

ln P = kh + C

Now, using the points given,

ln 101.5 = C, so C = 4.62

ln 87.3 = k*1000 + 4.62

k = -0.00015

So, we have

ln P = -0.00015 h + ln 101.5

P = 101.5 e^(-0.00015h)
