Which of the sets of ordered pairs represents a function? (4 points) A = {(−4, 5), (1, −1), (2, −2), (2, 3)} B = {(2, 2), (3, −2

A function will not have any repeating x values....it can have repeating y values, just not the x ones
(-4,5),(-1,1),(2,-2),(2,3)
this is not a function because it has 2 sets of points that has x as 2...so it has repeating x values
(2,2),(3,-2),(9,3),(9,-3)
this is not a function because it has 2 sets of points that has an x value of 9...so it also has repeating x values
so both of these are not functions.....neither of them
Answer: AC = A'C'
Then you can use the hypotenuse leg theorem to say that the two triangles are similar
Step-by-step explanation:
You can use Soh Cah Toa to get your answer, in other words, sin cos tan. If you already have x, that means you probably used tan, which is adjacent and opposite. Now for y, you are trying to find the hypotenuse so you could use, sin or cos, for sin you would use the adjacent (x) and the hypotenuse (y) and for cos, you would use opposite (4) and the hypotenuse (y). This is all based on the angle 45.
Answer:
6, 12, 24, 48 and 96.
Step-by-step explanation:
We look for a geometric sequence with first term = 3:
nth term= a1 r^(n-1)
3 r^(n-1) = 192
r^(n-1) = 192 / 3 = 64
2 ^ 6 = 64 so r = 2.
Series is 3 ,6, 12, 24, 48, 96, 192.
So 5 geometric means would be 6, 12, 24, 48 and 96.
