Answer:

Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel
And the anfle is approximately 
Step-by-step explanation:
For this case first we need to calculate the dot product of the vectors, and after this if the dot product is not equal to 0 we can calculate the angle between the two vectors in order to see if there are parallel or not.
a=[1,2,-2], b=[4,0,-3,]
The dot product on this case is:

Since the dot product is not equal to zero then the two vectors are not orthogonal.
Now we can calculate the magnitude of each vector like this:


And finally we can calculate the angle between the vectors like this:

And the angle is given by:

If we replace we got:

Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel
And the anfle is approximately 
I believe what your asking is just multiplying it together so 5p(p-3) would be 5p2-15p. the p2 is p squared or a little 2 on top of the p. Hope I helped!
Answer:
2x3+15x2+25x−6
Step-by-step explanation:
Multiply each term in the first expression by each term in the second expression and combine like terms.
19:76*100 =
( 19*100):76 =
1900:76 = 25%
Answer:
polite
Step-by-step explanation:
Peter's politeness never changes depending on circumstances, so it is a trait he owns.
