Which vector from exercise 8 would it make sense to call the opposite of v = 〈3,6〉?

-v

Step-by-step explanation:

The opposite vector is the vector that has the same magnitude of the original vector but points in opposite direction.So the vector -v has the same magnitude as the vector v but points to the opposite direction. Vector -v will start from the point 6 and will end at the point 3.That is opposite of the vector v which starts from point 3 and ends at point 6.

Hence the answer is -v.

the square root of what number? if you add that, then someone will probably answer the question.
