Be sure to answer all parts. Archaeologists can determine the
age of artifacts made of wood or bone by measuring the amount of
the radioactive isotope 14C present in the object. The amount of
isotope decreases in a first-order process. If 13.2% of the
original amount of 14C is present in a wooden tool at the time of
analysis, what is the age of the tool? The half-life of 14C is
5,730 yr. Give your answer in scientific notation.
