A 200 g sample of radioactive polonium-210 has a half-life of 138 days. This means that every 138 days, the amount of polonium left in a sample is half of the original amount. The mass of polonium, in grams, that remains after t days can be modelled by a) Create an algebraic model for the mass of polonium after t days. b) Determine the mass that remains after 5 years. c) How long does it take for this 200 g sample to decay to 110 g?
