Carbon dating exponential functions should you be friends before dating
(Whatever you're being treated for is the greater danger.) The half-life is just long enough for the doctors to have time to take their pictures.
The dose I was given is -younger copy of an earlier document (in which case it is odd that there are no references to it in other documents, since only famous works tended to be copied), or, which is more likely, this is a recent forgery written on a not-quite-old-enough ancient parchment.
However, I note that there is no beginning or ending amount given.
How am I supposed to figure out what the decay constant is?
In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.
This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.
If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.
I can do this by working from the definition of "half-life": in the given amount of time (in this case, hours.
I do not have the decay constant but, by using the half-life information, I can find it.
