Suppose strontium-90 decays at a rate of 2 percent per year.
(a) Write the fraction P of strontium remaining, as function of t, measured in years. (Assume that at time t=0 there is 100 % remaining.)
Answer: P(t) =
(b) Estimate the half-life of strontium.
Answer:
Hint: Use your graphing calculator and the trace function. (Or use natural logarithms as in 1.9).
(c) If presently there is 5.5 grams of strontium, estimate how many grams of the substance will remain after 11 years.
