Answer:
Option A.
Step-by-step explanation:
The vector shown in the figure has components on the x axis and on the y axis.
If each small box on the draw represents a unit, it can be seen that the vector has a component of<u> length equal to 1 on the positive y-axis </u>and a length equal to 4 on the positive x-axis.
Look at the attached image
The sum of these two components results in the vector shown in the figure. Therefore the correct option is option A.
The length is equal to 1
For absolute value, you are trying to figure out how many spaces it will take from that number to 0.
For example, if I was given the problem
| 3 |, I would ask myself "How do I get from 3 to 0? Since it takes you 3 spaces to get to 0, the answer will be 3. The same goes for any problem. If there is a negative sign in front of the absolute value, you add a negative to your answer.
hope that helps!
A and b cause there both half’s
