Analyze According to the data, what is the half-life of carbon-14? How can this information be used by scientists?CAN'T COPY THE GRAPH
Step 1
The half-life of a radioactive substance is the amount of time it takes for half of the substance to decay. In the case of Carbon-14, this is the time it takes for half of the Carbon-14 atoms in a sample to decay into Nitrogen-14. Show more…

Carbon-14 dating can be used to estimate the age of formerly living materials because the uptake of carbon-14 from carbon dioxide in the atmosphere stops once the organism dies. If tissue samples from a mummy contain about $81.0 \%$ of the carbon-14 expected in living tissue, how old is the mummy? The half-life for decay of carbon-14 is 5730 years.
The half-life of carbon-14 is 5715 y. How long will it be until only half of the carbon-14 in a sample remains?
Involve exponential decay. Scientists dating a fossil estimate that $20 \%$ of the original amount of carbon-14 is present. Recalling that the half-life is 5730 years, approximately how old is the fossil?
