the mean life of a radioactive nucleus. Show that 95% of the
radioactive nuclei originally present in a sample will disintegrate within three mean lifetimes, i.e., by time t=.
Thus, the mean life of a
k
nucleus gives a quick way to estimate how long the radioactivity of a sample will last.

If 95% of a sample has decayed, there is 5% remaining. How can you use the radioactivity equation y(t) = yo e
to find when 5% of the
sample is remaining?
A. Set y(t) equal to 0.05 and solve for t.
B. Evaluate y(0.05).
C. Set y(t) equal to 0.05y, and solve for t.
D. Evaluate y(5).
Perform the operation determined in the previous step.

The pressure at the Earth's surface (sea level) is about 14.7 pounds per square inch (psi) and the pressure at 500 feet is approximately 14.4 psi. If we let y be the air pressure in psi and x be the altitude in feet, then the pressure can be estimated as a function of altitude by using y=14.7(0.99996)x. (a) Predict the pressure in Quito, Ecuador (altitude 9350 ft): psi. Round to one decimal place. (b) Find the altitude when the air pressure is 4.62 psi.
