Question 1040454
.
Atmospheric pressure P (in kilopascals, kPa) at altitude h (in kilometers, km) is governed by the formula 

ln(P/P0 = -h/k

where k = 7 and P0 = 100 kPa are constants.

Solve the equation for P. 

I got 100e^{-k/7} WRONG!!!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{P/P0}}} = {{{e^(-(h/7))}}},

P = {{{P0*e^(-h/7)}}} = {{{100*e^(-h/7)}}} kPa.
