Answer:
to check the point collinear or not the give point is equal to zero..
Explanation:
here
x1=3, y1=4 ,x2= 3 ,y2=7 ,X3= 3 ,y3=9
now
1/2 [x1(y2-y3 ) + x2 (y3-y1 ) +x3 (y1 -y2) ]
= 1/2 [ 3 ( 7-9 ) + 3 ( 9- 4) + 3 ( 4-7 )
= 1/2 [ -6+ 15 -9 ]
= 1/2 [ 0]
= 0
hence the given point is collinear.
thank you ☺️❤️
Well, the answer will depend on what it means exactly to be "impaired" - I assume here that the question means "under the influence of alcohol".
Some studies have found an influence of alcohol consumption on reaction time, but it was more around 10% than 50 % -then the answer is "false". However, I can imagine than in some cases, for example when the reaction has to happen very fast or is difficult, it could be twice as slow. This is rather rare, and i would say that "double" is too much - false.
1) You had to pass a literary test. This prevented African American people from voting because many of them could not read.
2) A lot of states (the southern states) didn't think of African American people as people. They were property, in their eyes.
Can't help with the rest, sorry.
Popular music is said to have the widest audience and is believed to be the music of the Middle Class (this is the correct answer); the Upper class would listen to other kinds of music, such as Jazz and very specific kinds, while the Lower Class is said to listen to "folk music" -althought this might be changing, just like the definition of what is popular music is changing all the time.
