Question

Review the graph.

Answer 1

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

$\sqrt{(6-(-2)^2+(3-3)^2}\\\\\sqrt{(8)^2+(0)^2}$

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

$\sqrt{(8)^2+(0)^2} \\\\\sqrt{64+0}\\\\\sqrt{64}\\\\8$

Hope I explained it well and hopefully this helps!
