Answer:

Step-by-step explanation:

Intervals are always x values. When x = 5, y = 4 (look at the graph to se this); when x = 6, y = 2. The rate of change is the same thing as the slope. We can't get an exact slope here because this isn't a straight line, but we can find the average rate of change. We use the slope formula to do this: with the coordinates (5, 4) and (6, 2):

m=\frac{2-4}{6-5}=\frac{-2}{1}=-2. Third choice down is the one you want.

In 2010 there were 2000 American lions in a conservation park in Wisconsin. The lion population is decreasing
frez [133]

Step-by-step explanation:

After each year, the new population of the lions is 100% - 8% = 92% of the population of the lions the year before.

Hence our exponential base should be 0.92, indicating exponential decay. (A)
