The atmospheris pressure p on a ballon or plane decreases with increasing height.This pressure,measured in milimeters of mercury,is related to the number of kilometers h above sea level by the formula
p=760e -0.145h
a)Find the atmospheric pressure at a height of 2 kilometers.
b)What is it at a height of 10 kilometers

if y is the size of the colony and x is the original number of bacteria,
then y = x * 2^t (where t is the number is minutes)
when y = 4, t = 60
therefore, 4 = x * 2 ^ 60
therefore, x = 2 ^ -58
therefore, when y = 2,
2 = 2 ^ - 58 * 2 ^ t
2 ^ t = 2 ^ 59
therefore, t = 59
59 minutes looks like the right answer!

Pf=Po (e^rt)
Where:
Pf = final concentration
Po = initial concentration
rt = rate of growth x time
This is a basic buildup equation
