20. An anthropologist finds that a prehistoric bone contains less than 8.1% of the amount of Carbon-14 the bones would have contained when the person was alive. How long ago did this person die? (The constant for Carbon-14 is 0.00012)

Bacteria usually reproduce by a process called binary fission. In this type of reproduction one bacteria divides to form two bacteria. Under ideal conditions some bacteria reproduce every 15 minutes.

23. Find the constant k for this type of bacteria under ideal conditions.

24. Write the Equations for modeling the exponential growth of this bacteria.
