Factor the four-term polynomial.
pq - 3r + pr - 3q.
(p - 3)(q + r)
(p - r)(q + 3)
(p + 3)(q - r)

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)
