inis question. > polls) possible a. In 1975, a report estimated that a planet could reasonably support a maximum world population of 14 billion. The planet's population was approximately 3.4 billion and growing continuously at 3% per year. If this growth rate remained constant, in what year would the planet's population reach 14 billion, referred to as the carrying capacity? Use the model P= Po ek, where P is the population (in billions), Po = 3.4, k=0.03, and t is the number of years since 1975 b. The planet's population in 2000 was approximately 6.4 million. How does this compare with the population predicted by the growth model in part a? a. The carrying capacity would be reached in the year 2022 (Round down to the nearest whole number as needed.) b. The actual population was approximately | million below the prediction (Round to the nearest whole number as needed.)
