(5) Let p(t) denote the population of the Earth in the year t. According tothe internet, p(2017) = 7.55 billion. According to the lecture on populationgrowth, it is reasonable to assume thatdp/dt = kp − λp2with k = 0.029, λ = 2.695 × 10−12. Assuming all of this is true, answer thefollowing questions:(a) What will be the Earth’s population in 2030?(b) When “will” (or has it happened already?) the growth rate of theEarth’s population begin to decrease?(c) When did God create man? (That is: When were Adam and Evethe only two people on Earth? You will note that no major “religiousmythology” offers a figure as implausible as the one you will computefrom this model...)
