The number N, in millions, of hearing impaired people of age x can be approximated by N=0.00006x^2 - o1x + 1.1.Approximate to the nearest million the number of hearing impaired people of age 45 and 70.

To approximate the number of hearing impaired people of age 45 and 70 using the given equation N = 0.00006x^2 - 0.1x + 1.1, we substitue the respective ages into the equation.

For age 45:
N = 0.00006(45^2) - 0.1(45) + 1.1
N = 0.00006(2025) - 0.1(45) + 1.1
N = 0.1215 - 4.5 + 1.1
N = -3.279

For age 70:
N = 0.00006(70^2) - 0.1(70) + 1.1
N = 0.00006(4900) - 0.1(70) + 1.1
N = 0.294 - 7 + 1.1
N = -5.607

The approximations for the number of hearing impaired people of age 45 and 70 using this equation are -3.279 million and -5.607 million, respectively. However, it is important to note that the given equation provides negative values for these ages, which does not seem valid. Please check the equation or information provided.
