A certain radioactive isotope has a half-life of 11 days. If one is to make a table showing the half-life decay of a sample of this isotope from 32 grams to 1 gram; list the time (in days, starting with t = 0) in the first column and the mass remaining (in grams) in the second column, which type of sequence is used in the first column and which type of sequence is used in the second column?

Question

anonymous · Answer

this is exponential growth and decay matters just use first order separable ODEs

anonymous · Answer

solve for t=0 then solve for t=1 etc to build up the table

anonymous · Answer

by solving for t=0 you should get the proportional value (k) which you will use for the other t's
