Business A recent trend in advertising is viral marketing. The goal is to convince
viewers to share an amusing advertisement by e-mail or social networking. Imagine
that the video is sent to 100 people on day 1. Each person agrees to send the video to
5 people the next day, and to request that each of those people send it to 5 people the
day after they receive it. The number of viewers v(n) is an exponential function of the
number n of days since the video was first shown.
5.
A pharmaceutical company is testing a new antibiotic. The number of bacteria
present in a sample when the antibiotic is applied is 100,000. Each hour, the number
of bacteria present decreases by half. The number of bacteria remaining r(n) is an
exponential function of the number n of hours since the antibiotic was applied.

7. Optics A laser beam with an output of 5 milliwatts is
directed into a series of mirrors. The laser beam loses 1% of
its power every time it reflects off of a mirror. The power p(n)
is a function of the number n of reflections.
