Bacterial Growth A colony of bacteria grows according to the law of uninhibited growth according to the function Where N is measured in grams and t is in days. Determine the initial amount of bacteria What is the growth rate of bacteria What is the population after 5 days? How long will it take for the population to reach 140 grams? What is the doubling time for the population?

A colony of bacteria increases according to the law of uninhibited growth. If the number of bacteria doubles in 4 hours, find the function that gives the number of cells in the culture. How long will it take for the size of the colony to triple?

Estimating the Age of Ancient Tool Traces of burned wood along with ancient stone tools in an archeological dig in Chile were found to contain approximately 1.67% of the original amount of carbon 14. If the half-life of carbon 14 is 5600 years, approximately when was the tree cut and burned?

The size of a herbivore population at time t (in years) obeys the function After how many years will the population reach 3000? A) B) C) D)
