A sample of plutonium-240 decays according to the model
N(t)=23.89e−0.000106t
where N(t) is the amount remaining in grams and t is time in days.
What mass will remain after 426 hours? Round to 2 decimal places.
grams
I keep getting 22.83 grams but thats' wrong
0.000106t = -.045156
e-.045156=0.95584
0.95584(23.89)=22.83...where my error..thank you
