2. Given a natural logarithmic function Iny, for variables y ＞ 0 and x ＞ 0,calculate the right-hand side of the equation below is equal to the left-hand side.where z⁺ = max f{z, 0].

(13) A logistic population model with relative growth rate 0.1 per year and carrying capacity 50 thousand can be expressed by the differential equation =0.1P(1 - ), with P in thousands and t in years. Given that the initial population is 9 thousand. Find the population size after 20 years. (If you memorized the formula, then you need to derive it for this problem.)
