That is what I got also! checked by Morgan Miller magnitude: √ 52 =7.2111 magnitude:√ 49= 7 Done by:Valeria Chelala Thats what I got. Good job Valeria! Checked by Emily Johnson

The answers weren't posted yet, so here is my work: Checked By: Abby Demiano

10&12- I posted my work at about 5:30pm, but it has been deleted. Any who, I did the same thing as Abby and my answers are the same. -Kelsey harmon

The diagonal vector at the bottom is my answer vector, it's kind of hard to see but it says v-1/2u. Done by Ellen Barth

I got the same thing -Michael Herzberg

48. Done By: Shannon Wissel

I got The same answer Daniel Pugliano

I think I was supposed to check this one, I hope I'm not wrong. Good job, I got the same answer, I am not sure about the picture, you could include vectors -u and w so the resultant is obvious and I think the resultant should start at <0,0> and then go to <-1,3> Checked by Jan Dudek


 * 50

Done by Frances Dannenbrink I got the same answer. Checked by Andrew Kim

52) v=8cos135i + sin135j) IIvII = **8** Angle = **135** 54) v = -4i minus 7i IIvII = **Square root (65)** Angle = **330.225** I am supposed to check but won't be able to later so I am just posting my answers. Checked by : Courtney venable (52, 54) Well i guess i'm checking them technically now...but i got the same answers as courtney except the second angle i got to be 330.255 degrees. Done By: Blake Schreiber
 * #54: angle = 240.3 degrees **


 * 1) 56-#58 Done by: Kamryn Richard

I got the same answers 56&58 checked by : Emma McRae



That's what i got! checked by Alyssa Johnson
 * 1) 62 and #64 Done by Amy Finkelstein
 * #62 correction: **
 * you need to find the unit vector first, then multiply it by the magnitude **

75. sin40= y/70 y=70sin40 y=44.995 cos40= x/70 x=70cos40 x=53.623

76. sin4= y/1200 y=1200sin4 y=83.708 cos4=x/1200 x=1200cos4 x=1197.077

Done by Jennifer Hassell Sorry my internet was messing up all yesterday so I did it as soon as I could this morning!

85. True because magnitude is essentially length and if you have two vectors equal in length going the same direction, they're going to be equal.

86. True becausew the original equation for unit vectors was u=v/||v||, and if you rearrange it to solve for v, it's going to look like v=||v||u

85 & 85 Clarissa Rodriguez 85 and 86 Checked by MaTt BoGaErT- i got the same answers

87: v=ai+bj=0 v=<0,0> ai+bj=<0,0> ai=0 a=0 bj=0 b=0 0=-0 a=-b True

88: u=ai+bj u=||u||=√(a^2+b^2) √(a^2+b^2)=1 a^2+b^2=1 True
 * u||=1

Sorry, my computer is infected and i'm barely able to get on this right now. I got the same answers, Sam. Checked by Quinn Taylor.
