Suppose that from 2020 to 2060, the number of females in the U.S. under the age of 18, in millions, can be modeled byN=0.150x + 36.4where x is the number of years after 2020.(a) Viewing N as a function of x, what is the slope m of the graph of this function?(b) Interpret the slope as a rate of change.The slope m represents the number of females in the U.S., under age 18, in millions, in year 2060. Every m years, the population of females in the U.S., under age 18, in millions, is predicted to increase by 1.The slope m represents the number of females in the U.S., under age 18, in millions, in year 2020.Every year, the population of females in the U.S., under age 18, in millions, is predicted to increase by m.(c) What does the model predict the population of females under 18 (in millions) will be in 2040?
