An anthropologist has determined that a newly discovered human bone is 8000 years old. how much of the original amount of carbon

AlladinOne [14]

The original amount of carbon 14 that is in this bone is 38.29%

The formula that is used to determine the original amount of carbon 14 in the bone is given as:

$y = ae^-^0^.^0^0^0^1^2^t$

The value of t is given as 8000.

What is to be done is to solve the equation using the value of t

$y = ae^-^0^.^0^0^0^1^2^(^8^0^0^0^)$

= ae⁻⁰.⁹⁶

Solve for exp(-0.96)

y = 0.3829a

= 38.29%

Therefore the amount of carbon 14 that is in the bone is 38.29%
