The total world population is forecast to be P(t) = 0.00075t3 − 0.0716t2 + 0.99t + 6.04 (0 ≤ t ≤ 10) in year t, where t is measured in decades, with t = 0 corresponding to 2000 and P(t) is measured in billions. World population is forecast to peak in what year? Hint: Use the quadratic formula. (Remember that t is in decades and not in years. Round your answer down to the nearest year.) ___________

World Population

The total world population is forecast to be

P(t) = 0.00075t³ − 0.0716t² + 0.99t + 6.04 (0 ≤ t ≤ 10)

in year t, where t is measured in decades, with t = 0 corresponding to 2000 and P(t) is measured in billions.

World population is forecast to peak in what year? Hint: Use the quadratic formula. (Remember that t is in decades and not in years. Round your answer down to the nearest year.) ___________

Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
