Alright soooo, im glad carnival ball is over. But now i'm going to fail this class. ALEKS is not my friend anymore. I work too slow and i havent met the latest deadline which will cause my grade to go wayyyyyyy down. The assessment test sucksssssssssssss.
glad ive said that now on to some math.

Finding whether something is parallel or perpendicular is my favorite.

EXAMPLE:
j=(3,4,2) k=(15,8,4)
PARALLEL:
15/3=5
8/4=2
4/2=2

PERPENDICULAR:
3(15)+4(8)-2(4)
**in order for it to be perpendicular it must equal 0.
****therefore its neither.


The AB thing is easy too.
A(2,3,1) B(4,2,6)
4-2=2
2-3=-1
6-1=5
*your answer is (2,-1,5)

my computer keeps freezing so im going to post now.
