Answer 3

\[\large
N(t) = \frac{300}{1+299e^{-0.36t}}
\]

Answer 4

For b) put t = 0
N(0) = 300 / (1 + 299 * 1) = 300/300 = 1 (True).

Answer 5

For c) put t= 14 and see if N(t) = 100.
N(t) = 300 / { 1 + 299 * e^(-0.36 * 14) } = 102 which is approximately 100.
So it is true.

Answer 6

d) As t becomes large, N(t) becomes close to 300.
So there are 300 people in the enclosed space.

Answer 7

a) is true as the rumor spreads at an exponential rate.
