Concept explainers
Population of Children The following table gives the estimated population (in millions) of U.S. boys age 5 and under and U.S. girls age 5 and under in selected years.
A function that models the population (in millions) of U.S. boys age 5 and under t years after 1990 is B(t) = 0.0076t2 – 0.1752t + 10.705, and a function that models the population (in millions) of U.S. girls age 5 and under t years after 1990 is G(t) = 0.0064t2 – 0.1448t + 10.12.
a. Find the equation of a function that models the estimated U.S. population (in millions) of children age 5 and under t years after 1990.
b. Use the result of part (a) to estimate the U.S. population of children age 5 and under in 2003.
