Answer 2

Answer:

The approximate difference in the growth rate of the two populations is 40%.

Step-by-step explanation:

The general exponential growth model is

$y=a(1+r)^t$

Where, a is initial value, r is growth rate and t is time.

In the given graph, red curve passing through the points (2,22.5) and (3,33.75).

$22.5=a(1+r)^2$           .... (1)

$33.75=a(1+r)^3$           .... (2)

Divide the equation (2) by equation (1).

$1.5=1+r$

$0.5=r$

The graph rate of red curve is 50%.

In the given graph, purple curve passing through the points (7,19.4) and (8,21.4).

$19.4=a(1+r)^7$           .... (3)

$21.4=a(1+r)^8$           .... (4)

Divide the equation (4) by equation (3).

$1.1031=1+r$

$0.1031=r$

$0.1\approx r$

The graph rate of red curve is 10%.

The approximate difference in the growth rate of the two populations is

$50-10=40\%$

Therefore the approximate difference in the growth rate of the two populations is 40%.
