Question

Air pressure may be represented as a function of height above the surface of the Earth as shown below.
P(h)=PoE^-.00012h

In this function, P0 is air pressure at sea level, and h is measured in meters. Which of the following equations will find the height at which air pressure is 65% of the air pressure at sea level?

A. Po=.65PoE^-.00012h

B. .65Po=PoE^-.00012h

C. .65=h*e^-.00012

D. h=.65e^-.00012

Answer 1

P(h) is air pressure at height h and P0 is air pressure at sea level.
"air pressure is 65% of the air pressure at sea level" means:
P(h) = p0 * 65/100 = 0.65p0

Which one has P(h) replaced by 0.65p0 ?

Answer 2

would it be B?
