There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.
The domain is B. -8 ≤ x < 3 and 4 ≤ x < 8
Answer:
It is reasonable.
Step-by-step explanation:
If you add 468 (amount of animals already there) and add how ever many more coming (192) then you'll get 680. If you add 100 more that will only be 780 animals.
I'm not 100% sure, but I believe the answer is A. x²-5/4x+1
