(1 point) The world population is modeled by the function P(t) = 7.358(1.014)* where P is the population in billions and t is the time in years since 2015. According to this model, what will the population be in 2040? The population in 2040 will be billion. Find the function that models the rate that the population is changing each year and determine by how many people per year the population is growing in 2040. The function that models the change in population each year is P' (t) At 2040, the population will be growing at a rate of billion people per year. ( Round numerical answers to three decimal places.)
