WebDec 28, 2016 · Differential Equation_Half Life 1. 1 2. Differential Equation DEFINITION An equation containing the derivatives of one or more dependent variables, with respect to one or more independent … WebTo complete the equation that models this population, we need to find the relative decay rate k. We can use the half life of the substance to do this. The half life of Bismuth-210 is 5 days. This says that after t = 5, the original population of 800 mg has decay to half of its original amount, or (800) 400 2 1
