At the beginning of an experiment, a scientist has 316 grams of radioactive goo. After 225 minutes, her sample has decayed to 4.9375 grams. What is the half-life of the goo in minutes? :] Find a formula for C(t], the amount of goo remaining at time t. G6) = |:| How many grams of goo will remain after 29 minutes? C] The count in a bacteria culture was 300 after 20 minutes and 1001] after 40 minutes. Assuming the count grows exponentially, What was the initial size of the culture? Z] Find the doubling period. :1 Find the population after 75 minutes. :] When will the population reach 11000. |
