Prove 1.) Assume that the population of a certain city increases at a rate proportional to the number of inhabitants that is presently living. If the population doubles in 2 years, and after 3 yes is 20,000, now what is the estimated initial residents living in city? Answer : 7062 2.) Compute its maximum speed in km/h, of a vehicle whose velocity v (in m/s) is a function of time (in secs) acc to the eq v = 4.5 + 18t - 4.5 t2 Ans: 22.5
