Answer:
first top left graph? 12×4 is 48 so that puts it about right
Answer: 8/17 :)
hope it helps
Answer: A, Magnitude of 8 and direction angle equal to 0°
Step-by-step explanation:
Since vector u is only a straight line, there will be no angle, which means that answers B and D are automatically wrong.
Now, we’re going to use the distance formula to find the component form of vector u

Now we found the new coordinate, which is (8,0), and it is being extended from the origin with the same angle of 0°
Using the formula from above, we can find the magnitude of vector u

Hope I explained it well and hopefully this helps!
Answer: (-4, -7)
I dont know how to explain how I got that but I recommend using an app called Desmos. :)
You just add up all of the sides to find the x
