Asked by Brittany
In the year 2005, a picture supposedly painted by a famous artist some time after 1815 but before 1865 contains 96.5 percent of its carbon-14 (half-life 5730 years).
From this information, could this picture have been painted by this artist?
Approximately how old is the painting?

.965= (1/2)^(t/5730)
take the ln of each side
ln(.965)=t/5730 * ln (1/2)
solve for t.
I get about 300 years ago it was painted.
