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?

6
  • 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?
