6=14.7e^-0.0000385h

Question

6=14.7e^-0.0000385h

brinazarski · Answer

How do you solve this? :(

anonymous · Answer

is the h a unit of measurement?

brinazarski · Answer

Yup

brinazarski · Answer

The air pressure p(h) (in lb/in2) at an altitude of h feet above sea level may be approximated by the following formula. At approximately what altitude h is the air pressure 6 lb/in2? (Round to the nearest foot.)

anonymous · Answer

ok, take divide both sides by 14.7 and take the natural log (ln) of both sides to get h= #

brinazarski · Answer

wait... so ln(6/14.7)=-0.0000385h?

anonymous · Answer

yes

brinazarski · Answer

But then you run into the same problem... e^x = 6/14.7

brinazarski · Answer

Until you solve for x, you can't solve for h

$\bf \large  6=14.7e^{-0.0000385h} \quad ?$

brinazarski · Answer

mhmm

anonymous · Answer

try getting a number for ln(6/14.7)   [my calc says -0.896088024556635]
and then divide by -0.0000385

brinazarski · Answer

Oh...

anonymous · Answer

FYI h is not a unit of measurement, it is the variable
