Answer:
C. 20
Step-by-step explanation:
You need you use the Pythagorean Theorem to answer this. We are given the lengths of both legs of the right triangle.
a^2 +b^2 = c^2
If we plug the number given to us into the formula, we get
(12)^2 + (16)^2 = c^2
144 + 256 = c^2
400 = c^2
= C
20 = C
I think 24.6 if I’m not right I’m so sorry
I believe the answer is 13.
Look at the first element of each point:
{4, 1, 0, 1} (do not write 4 twice, even tho' 4 shows up twice).
This is NOT a function, altho' it still is a relationship. Why? Because 4 shows up as an input twice. In the case of a function, no input shows up more than once.
