Using the table below, find the average rate of change of population from 1990 to 2000. The population represents f(x) and the year represents x year.

1970 1980 1990 2000
population (million) 2.1
6.4
9.2
10.5
Possible answers
-0.13 million per year
0.13 million per year
7.69 million per year
-7.69 million per year

based on context clues you gave i'm assuming the answer would be c.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
