<u>Sum of vectors in</u> ![\mathbb{R}^2](https://tex.z-dn.net/?f=%5Cmathbb%7BR%7D%5E2)
Given two vectors
and
. The sum of both vectors is:
![\vec a+\vec b =](https://tex.z-dn.net/?f=%5Cvec%20a%2B%5Cvec%20b%20%3D%3Cx%2Bw%2Cy%2Bz%3E)
The vectors in the figure are
![\vec a=](https://tex.z-dn.net/?f=%5Cvec%20a%3D%3C-3%2C4%3E)
![\vec b=](https://tex.z-dn.net/?f=%5Cvec%20b%3D%3C-4%2C-2%3E)
The sum is
![\vec c=\vec a+\vec b =](https://tex.z-dn.net/?f=%5Cvec%20c%3D%5Cvec%20a%2B%5Cvec%20b%20%3D%3C-3-4%2C4-2%3E)
![\vec c=](https://tex.z-dn.net/?f=%5Cvec%20c%3D%3C-7%2C2%3E)
Option B
Answer:
d, as long as distance is y(up) and time is x(across)
Step-by-step explanation:
a. the graph would go up and then slow down. b. the graph could be this. d. distance does not look like this.
Answer: The circumference of a circle is equal to Pi π times the diameter d . Since the diameter d is equal to 2 times the radius r , the formula for circumference using radius is 2πr 2 π r .
