At the beginning of an experiment, a scientist has 236 grams of radioactive goo. After 225 minutes, her sample has decayed to 7.375 grams. What is the half-life of the goo in minutes? Round your answer to the nearest hundredth. Find a formula for G(t), the amount of goo remaining after t minutes. Round any decimals to 6 decimal places. G(t) = How many grams of goo will remain after 32 minutes? Round your answer to the nearest hundredth.
