QUESTION 3. Submit all steps, code, script, solutions, plots, etc. [Mark: 2.5] Someone has an accident in a swimming pool. The disappearance or decay rate ofthe contaminant can be estimated as dC/dt = k C decay where C is the concentration of the contaminant, t is time, and the decay constant k = 0.001Q1 S 1. decay How long should the pool be vacant if the initial concentration is 7Q200 ppm and the safety threshold is 50 ppm? Plot the concentration with respect to time for this range of concentration. Here, cq and a 2 are the largest and second largest digits, respectively, of your student ID. For example, ID = 110 733 456 gives cq = 7 and ct2 = 6, that is k = 0.0017 s-l and 7600 ppm. decay
