Question

The polynomial negative 8.5 x squared plus 103 x plus 2026−8.5x2+103x+2026 models the yearly number of visitors​ (in thousands) x years after 20062006 to a park. Use this polynomial to estimate the number of visitors to the park in 20182018.

Answer 1

2038000 visitors

Explanation:

Now in question expression has been repeated, so original expression is

`-8.5x^2+103x+2026`

Now according to given information "x" represent the number of years after 2006. So, for 2018, it will be

2018-2006 = 12 years

So, x = 12

putting value of x in expression

(-8.5)x(12)^2 + (103)x(12) + 2026

-1224 + 1236 + 2026

2038

Now the model shows the number of visitors in thousand, so you have to multiply your answer in thousand

2038 x 1000

= 2038000 visitors
