Answer:

Average rate of change = 10

Explanation:

Average rate of change = \frac{f(b) - f(a)}{b - a}

a = 2

f(a) = f(2) = (-2)² + 3(2) + 1 = 4 + 6 + 1

f(a) = 11

b = 5

f(b) = f(5) = (-5)² + 3(5) + 1 = 25 + 15 + 1

f(b) = 41

Thus:

Average rate of change = \frac{41 - 11}{5 - 2}

= \frac{30}{3} = 10

Average rate of change = 10

vfiekz [6]
Assuming we don't know the speed capabilities of the tractor, the time it would take simply be the rate in miles per hour. It has a direct correlation between speed and time spent, so the miles the tractor needs to plow is unneeded.

We can calculate that a country would lower its arithmetic density by
adelina 88 [10]

Answer:

C.

Explanation:

Hi, fellow AP Human Geographer. Basically, all that arithmetic density means the total number of people per unit of land area. Having said that, we can immediately eliminate A. because increasing the population would only increase the total number of ppl. per unit of land area. Next, B. B can work, theoretically; however, there is a better answer. Next, D. D. says limiting the number of farmers; while this will technically reduce the number of ppl. per unit of land area, again there is a better answer. Next, E. I'd say this is the toughest choice; however, by increasing the area of urban areas, it can end up attracting more people instead. Overall, the best answer would be C., limiting the size of the population.
