Question

In a new suburb, it is estimated that the number of registered voters will be modeled by the function N(t) = 11 + 9 t^2 - t^3, where t is time in years and N is in thousands.

N(4) = ? ________ which represents ? _______(how many voters)

Answer 1

I wish I could help, man my teacher was just going over that

Answer 2

N(4) represents the number of thousands of voters in four (4) years
N(t) = 11 + 9 t^2 - t^3
N(4) = 11 + 9 *4^2 - 4^3
N(4) = 11 + 9*16 - 64
N(4) = 11 + 144 - 64
N(4) = 155 - 64
N(4) = 91 thousand voters in four (4) years

Answer 3

N(4) represents the number of thousands of voters in four (4) years
\[N(t) = 11 + 9 t^2 - t^3 \]\[N(4) = 11 + 9 *4^2 - 4^3\]\[N(4) = 11 + 9*16 - 64\]\[N(4) = 11 + 144 - 64\]\[N(4) = 155 - 64\]N(4) = 91 thousand voters in four (4) years
