You can put this solution on YOUR website! the amount of radioactive substance present, in grams, at time t months is gven by the formula y=6000(2)^-0.3t. Find the number of grams present in 3 years. If necessary, round to 3 decimal places.
------------------------
y=6000(2)^-0.3t
f(36) = 6000*2^(-0.3*36)
---
f(36) = 6000*2^(-10.8) =
---
f(36) = 3.3653 grams
