Decay Problem A zircon sample contains 4000 atoms of the radioactive element 235U. Given that 235U has a half-life of 700 million years, how long would it take to decay to 125 atoms? Solve the equation via MATLAB making sure that you passed though the following: 1. Initialization of variables 2. Setting up the differential equations 3. Listing down initial Conditions Script 4. Solving for the parameter k 5. Finding the resulting model 6. Finding the period where the amount will be 125 atoms 7 Graph the solutions 1 %A zircon sample contains 5000 atoms of the radioactive element 2350. 2 %Given that 235U has a half- life of 650 million years, how long would it take to decay to 120 atoms? 3 Save 4 %Setup the variables A(t), k that will be used in the program.
