Question

No. 1,2,3&4please. Please don't just solve one of the problems. please be sure to solve all of them with a graph. I've tried multiple times to solve them but I got them all wrong.

Pages Do not just do your homework, you need to learn from your homework. Idens that you se to answer estions on this homework will also be expected to be used in the future, so you need to really understand w to do each of these problems so that you can answer similar problems later. This is especially true for any rms I define in the homework - these are terms may not go over in class but you are still expected to know. Problems labeled with [P] require a picture, graph, or diagram, and no credit will be given to work ithout an appropriate picture. These pictures do not have to be exact, but do have to describe the situation. 1. (P) Graph the following system in Rº and determine the number of dimensions of the graph. >1-4 3y +=0 2. [PJ Graph the equation +y 9 in Rand determine the number of dimensions of the graph. 3. [P] Graph the following system in Rand determine the number of dimensions of the graph. (12 + y2 +254 20 ly : 20 4. P) Draw the following vectors in either R or R', depending on the number of components. Then calculate the length of the vector. (a) (2,5) (c) (-5, -2) (e) (-3,1,1) (b) (6,-2) (d) (1,3,-4) (1) (2, -3,6)

Answer 1

The graph of y'> &-4 is the area inscribed in the parabola x-4 (as arrowed) and à l is the line ginen by 34+x=0 So both they represent the line A, A₂ 2.

The cylinder in the picture is the equation of As, this is represent by (x, 19-2", 2) it has two dependent veniable & and 2, it's dimension=2 To i It is a sphre with radius 2. Now, x0,970 and 2) to represent the first quadrant of the sphere only and (2,4, 2) = (x, y, J4-x*y 2 ) So dimension = 2 7 y 2. 6-5-43-2-18 123456 (-51-2) • (6,-2) 9722 XH/23456 For (x, y, z) First go to (0,0,0) then goto (1970) & then go to verticle and get (2,1,2) direction 28tep
