In 2006, the murder of Alexander Litvinenko, a Russian dissident, was thought to be by poisoning from the rare and highly radioactive element polonium-210 t 138.4 210, 210, (210 Po). The half-life of Po is 138.4 yr. If 0.8 mg of Po is present in a sample then A (t)=0.81 gives the amount A (t) (in mg) present after t years. Evaluate the function for the given values of t and interpret the meaning in context. Round to 3 decimal places if necessary. (a) A (138.4) (b) A (276.8) (c) A (400) In 2006, the murder of Alexander Litvinenko, a Russian dissident, was thought to be by poisoning from the rare and highly radioactive element polonium-210 t 138.4 210, 210, (210 Po).
