Zipf's Law, developed by George Zipf in 1949, states that in a given country, the population of a city is inversely proportional to the city's rank by size in the country.116 Assuming Zipf's Law:(a)Write a formula for the population, P, of a city as a function of its rank, R.(b)If the constant of proportionality k is 300,000, what is the approximate population of the largest city (rank 1)? The second largest city (rank 2)? The third largest city?(c)Answer the questions of part (b) if k = 6 million.(d)Interpret the meaning of the constant of proportionality k in this context.
