Answer:
y = 0
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel. Then segment CD must be parallel to AB, and CB must be parallel to DA. Two different segments are parallel if they have the same slope.
slope of DA = (yA - yD)/(xA - xD) = (4 - 2)/(1 - (-1)) = 1
slope of CB = (yB - yC)/(xB - xC) = (2 - yC)/(1 - (-1)) = 1
(2 - yC) = 2 * 1
2 - 2 = yC
0 = yC
Note: coordinates of A are (xA, yA), of B are (xB, yB), of C are (xC, yC) and of D are (xD, yD)
Answer:

Answer:
I think is D if you not sure you can go to google check.
Answer:
476.25 hertz
Step-by-step explanation:
Since the speed of a wave is the wave length multiplied by the frequency, the frequency can be written as the speed divided by the wave length. 3810/8=476.25 hZ. Hope this helps!
