Answer:
Option c
Step-by-step explanation:
We are being asked to find unit vector u given the direction as x = < 40, 9 >. In most cases it would be v = < 40, 9 >, but it is the same concept.
To find the magnitude, given 40 and 9, you would do the following -
We got the magnitude to be 41. Now let us find unit vector u through the following calculations -
And there you have it! <u><em>The solution is option c! </em></u>
Answer: First option.
Step-by-step explanation:
You know that the meaning of the symbol of the inequality "<" is: Less than.
So, you can check each option to find the number that could be a length of this piece of wood.
Given , you can substitute each number given in the options into this inequality. Then:
Therefore, a lenght of the piece of wood could be 4.5
