jim_thompson5910 · Answer

$$\Large p(h) = Pe^{-0.0012h}$$ right?

anonymous · Answer

yeah

jim_thompson5910 · Answer

P0 is the air pressure at sea level

75% of this means we have 0.75*P0, agreed?

anonymous · Answer

ok

jim_thompson5910 · Answer

$$\Large p(h) = Pe^{-0.0012h}$$

$$\Large 0.75*P_{0} = P_{0}e^{-0.0012h}$$

and you solve for h from there

so would it be the first answer A?
