(1 point) P of a population P(t) is given in the figure above. By approximately P(t) A graph of the relative growth rate what percentage does the population change over the 9 year period? Answer: %. Clarification: As in Example 1 on page 290 of your textbook, first find factor by which the population has increased, i.e., K = P(9)/P(0), or equivalently, P(9) = Р(9) — Р(0) —D КР(0) KP(0). Then the amount of the increase itself is P(0) (K...
