Vectors

Well thank you so much Eddie for choosing me for scribe, since you tried to be mean and it backfired because we had a substitute,haha. But enough of fun and games our substitute was Mr.Kidd, who went over Study guide 4 (section 4.2:Components of Vectors), so I will supply you with the answers for anyone who didn't get them,
1) b. 90°
2) b. origin
3) c. quadrant 3
4) b. B
5) d. sinΘ=B(у)/B
6) c. cosΘ=D(x)/D
7)
c. C
8) b. FsinΘ
9) c. FcosΘ
10) c. E
11) c. R(x)= (-1.4 km) + 4.0 km + 1.5 km = 4.1 km
12) c. R(y)= (-3.8 km) + 6.9 km + (-1.3 km) = 1.8 km
13) a. R<>
14) c. Y=-R
Mr. Kidd was also nice enough to help us with our vectors assignment and went over all the questions and showed us how to do them! But I'm pretty sure that we'll go over them again with Ms. K when she returns. So I'll leave that for the next scribe which will be nounith1.
