Question

Suppose that the quadratic equation

S=0.0654x² -0.902x + 8.84 models sales of new cars, where
S represents sales in millions, and x = 0 represents 2000, x=1
represents 2001, and so on. Which equation should be used to
determine sales in 2020?
...

Answer 1

Hi,

Explanation:

x=20 represents 2020.

`S(x)=0.0654x^2 -0.902x + 8.84 \\\\S(20)=S=0.0654*20^2 -0.902*20 + 8.84 =16,96 \ (millions\ )`
