Answer:

Option A

Step-by-step explanation:

A'B' is 1/2 times the AB as the scale factor is 1/2.

Find the length of AB using distance formula.

AB = $\sqrt{(4 - 2)^2 + (4-0)^2} = \sqrt{20} = 2\sqrt{5}$

And find A'B':

A'B' = 1/2*2 $\sqrt{5} = \sqrt{5}$

Correct choice is A

You are going to model the population size of a species of bird that is gradually becoming extinct. Which graph is the BEST choi

kvasek [131]

Hey Jay,
Since we can't see the graphs, we can't be entirely sure, but given that we are trying to model the population size of a species of bird that is slowly going extinct. I would say the best graph would be a line graph. Line graphs show changes over time so this would be the best graph to use. Hope this helped!

Cheers,
Izzy
