A bacteria culture initially contains 2500 bacteria and doubles every half hour. Find the size of the baterial population after 100 minutes. Find the size of the baterial population after 9 hours. At the beginning of an experiment, a scientist has 180 grams of radioactive goo. After 255 minutes, her sample has decayed to 5.625 grams. What is the half-life of the goo in minutes? Z] Find a formula for G(t), the amount of goo remaining at time t. G(t) = How many grams of goo will remain after 59 minutes? C] A wooden artifact from an ancient tomb contains 40 percent of the carbon-14 that is present in living trees. How long ago, to the nearest year, was the artifact made? (The half-life of carbon-14 is 5730 years.) The count in a bacteria culture was 400 after 20 minutes and 1000 after 30 minutes. Assuming the count grows exponentially, What was the initial size of the culture? C] bacteria Find the doubling period. :] minutes Find the population after 75 minutes. C] bacteria When will the population reach 12000. C] minutes The doubling period of a bacterial population is 20 minutes. At time t = 90 minutes, the bacterial population was 50000. What was the initial population at time t = 0? Find the size of the bacterial population after 4 hours
