ok so i got...

Question

the half life of carbon-14 is 5730 years, the relation c+(1/2)^ N/5730 is used to calc. the concentration, c, in parts per trillion remaining n years after death determine the carbon concentration in a 11460 year old bone.
please help :)

Answer 1

You must be kidding. No capitals to begin the sentence and no periods at the end of a sentence. I can't find the question. But I can tell it's a half-life question.

I don't use your formula. I used a revised version which always gives the same result.
Calculate k. k = 0.693/t_1/2
Then substitute k into the following.
ln(No/N) = kt
k is from above.
No is what you started with. I would assume a value of 1
N is what is left.
t is the time in the problem.
Post your work in readable form if you get stuck.
