I think if the time is zero, there is no decay so x is equal to ZERO

that means lambda is dx/dt, right? As u said, I do the calculation and find the follow ln|x| = -bt +C where C is a constant then what should I do? Can u explain more details?

t0 =0, x0 = 0 When t = 5230, then I dun no how to find the X=? then can't find the lambda?

The half-life of a radioactive isotope is the amount of time it takes for a quantity of radioactive material to decay to one-half of its original amount. i) The half-life of Carbon 14 (C-14) is 5230 years. Determine the decay-rate parameter  for C − 14. ii)The half-life of Iodine 131...
