Question 7628: The amount of a radioactive tracer remaining after t days is given
by A = A0 e^–0.18t, where A0 is the starting amount at the beginning of
the time period. How much should be acquired now to have 40
grams remaining after 3 days? Answer by prince_abubu(198) (Show Source):
You can put this solution on YOUR website! So the A-final will be 40 grams, right, and you want to know how much you started with 3 days ago? Let's see:
<---- simplified.
<---- divide both sides by .
<---- Calculate using calculator. You should get approximately 68.64 grams three days ago.
Calculators differ a lot when it comes to how to punch buttons to compute "e to the something" power, so I can't really explain this part to you.
