Step-by-step explanation:
H
Answer:-5 per 2
Step-by-step explanation:m= y1-y2perx1-x2
=–8–7per–4–2 = –15per–6 = –5 per 2
All of them except the second one .
Answer:
C has a magnitud of 10.4 units and is directed 270° from the positive x-axis
Step-by-step explanation:
As it shows on the attached picture, the xA and xB have equal magnitudes but opposite directions, therefore they cancel eachother out in the x-axis.
However, the yA and yB are equal in magnitud, but have the same direction. So, the create a total vector the is completely on the y-axis and it's magnitude is 2*(sin(60°)*6)=10.4 units.
In order for C to cancel this vector, it's magnitude also needs to be 10.4 units, but pointing the other way. Therefore, the angle needs to be 270° from the positive x-axis.
Answer: B
-14 - 2x - 10 + 3y + 8x - 16y
Put everything in order so it is easy to combine like terms.
-2x + 8x + 3y - 16y - 14 - 10
Combine like terms. That means that you should add both x's together, add both y's together, and add both numbers together.
6x - 13y - 24
B is your answer! If you are confused on why B looks different, it is becuase the variables/numbers are in mixed up places. I hope this helps you!
