Chapter 8, Problem 32(choose chapter or problem)
Polonium-210 is a radioactive element with a half-life of 140 days. Assume that 10 milligrams of the element are placed in a lead container and that \(y(t)\)) is the number of milligrams present \(t\) days later.
(a) Find an initial-value problem whose solution is \(y(t)\).
(b) Find a formula for \(y(t)\).
(c) How many milligrams will be present after 10 weeks?
(d) How long will it take for 70% of the original sample to decay?
