Answer:
D. on edge
Step-by-step explanation:
Define unit vectors along the x-axis and the y-axis as
![\hat{i} , \, \hat{j}](https://tex.z-dn.net/?f=%5Chat%7Bi%7D%20%2C%20%5C%2C%20%5Chat%7Bj%7D)
respectively.
Then the vector from P to Q is
![\vec{PQ} = (-13+5)\hat{i} + (10-5)\hat{j} = -8\hat{i} + 5\hat{j}](https://tex.z-dn.net/?f=%5Cvec%7BPQ%7D%20%3D%20%28-13%2B5%29%5Chat%7Bi%7D%20%2B%20%2810-5%29%5Chat%7Bj%7D%20%3D%20-8%5Chat%7Bi%7D%20%2B%205%5Chat%7Bj%7D)
In component form, the vector PQ is (-8,5).
The magnitude of vector PQ is
√[(-8)² + 5²] = √(89) = 9.434
Answer:
The vector PQ is (-8, 5) and its magnitude is √89 (or 9.434).
Answer:
Line B
Step-by-step explanation:
Line B would best fit the scatter plot because the dots aline most similar to how Line B does. If you were to look at the angle Line B is at, most of the dots line up in the way Line B does. Therefore, Line B best fits the scatter plot.
To square means to multiply something by itself. A variable is a letter such as x. So a squared variable=x×x=x^2.
I hope that helped.
