A major corporation is building a 4325 acre complex of homes, offices, stores, schools, and churches in the rural community of G
denis23 [38]

Answer:

1) P(0) = 5000

2) P(t --> ∞) = 25000

Step-by-step explanation:

P(t) = (25t² + 125t + 200)/(t² + 5t + 40)

1) Population at the moment corresponds to population at t = 0

P(0) = (25(0²) + 125(0) + 200)/(0² + 5(0) + 40) = (0 + 0 + 200)/(0 + 0 + 40) = 5 thousand = 5000 (P was stated to be in thousands)

2) Population in the long term corresponds to the population as t --> ∞

P(t) = (25t² + 125t + 200)/(t² + 5t + 40)

Divide through the numerator and denominator by t²

P(t) = (25 + (125/t) + (200/t²))/(1 + 5/t + (40/t²))

P(t --> ∞) = (25 + 0 + 0)/(1 + 0 + 0) (Since, (1/∞) = 0)

P(t --> ∞) = 25 thousand = 25000
