Answer to Question #56716 in Calculus for Butch DeLoria

Question

Air pressure may be represented as a function of height above the surface of earth as shown below.
p(h) = Poe^ -.00012h

1: 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 75% of the air pressure at sea level?

A: 0.75Po=Poe^-0.00012h
B: Po=0.75Poe^-0.00012h
C: h=0.75e^-0.00012
D: 0.75=h ∙ e^-0.00012

2: If you put $ 2,000 in a savings account that pays 6% interest compounded continuously, how much money will you have in your account in 4 years? Assume you make no additional deposits or withdraws.

A: $2,983.65
B: $2,542.50
