The first thing i'm going to point out is that we have this decay formula.
00:07
So it's up to you how you want to do.
00:09
Maybe you do c for carbon 14 for the amount of time.
00:13
But it's based off the initial amount and then one minus the decay rate to the t over k power if it takes that many years to decay at that rate.
00:27
So if i'm setting up a formula for carbon 14, well, what you can actually do is have this starting point be like it's 100%.
00:44
Or you can leave it as a decimal, which would be 1.
00:47
But i think i'm going to leave it as 100%.
00:50
And i give you my answer as a percent, but then i can always change it back.
00:55
Or how about this? let's leave it as 1.
00:58
And then i'll change it to a percent at the end.
01:01
So 1 minus it decays at 11 .4%.
01:07
So you have to change that to a decimal .1 .14.
01:11
And it tells you that it takes over, or it takes every thousand years to decay that much...
