For the following exercises, the vectors $\mathbf{a}, \mathbf{b},$ and $\mathbf{c}$ are given. Determine the vectors $(\mathbf{a} \cdot \mathbf{b}) \mathbf{c} \quad$ and $\quad(\mathbf{a} \cdot \mathbf{c}) \mathbf{b}$ Express the vectors in component form.
$$
\mathbf{a}=\langle 2,0,-3\rangle
$$
$$
\mathbf{b}=\langle- 4,-7,1\rangle
$$
$$
\mathbf{c}=\langle 1,1,-1\rangle
$$

Can we have that? A zinc lozenges will cover one, too. B is equal to negative one common Cheryl Comma one and C is equal to one common. Joe. Come in a bit of one. Get her ass for a don't beat. But it's this zero. China's native one 1st 1 times l look two turns one that used me too grass for a Nazi. They're old times one plus one time so close to the times, thinking of you. It's there's no back here. And that's the sequel to negative shit. Okay, now we're asked for a dot B times C That's equal to that. See, we said C was or it'll be was two. And in times our vector. See, it's one Comma Joe combination of one. It's just equal to two common Darryl combination, too. And then we have a doxy times be He said it Nazi was negative. We have negative two times our vector B. Just one call material Come Oh one. And that gives me to comment. Zero coming there too

So in this example they give us three displacement factors and their X and Y components. And they asked us to find the X and Y component of our resultant and then the graph it. So we know that the X and Y component of the resultant are just going to be the some of the x components of our displacement vectors and the sum of our white components of our displacement vectors. So our X components going to come out to positive one and R a Y component when these are added together will come out to negative 11. So if this is our origin, I'm gonna go one to the right and 11 down. That might not be the best arrow, but we get the point and that will be our resultant.

Hello I'm your pizza for this question Let me extend this for self you know give him given component of vector paid component of victory along the X axis. It is represented by A. S Which is 4-6 and along to Y. Axis which is given nine. and component of Victor belong we have sex is is given 6 7 and component of Victor Victor be around. Why you exist is given -3. Similarly component of electricity along the X-axis is given zero and component of electricity around the why you exist it is given -6. So we have to find when you have a plus b. I mean there is a plus B A B C. And it is forwarding the question we have to solve those questions. So left rather diagram for this question. So with the help of designer we can understand what being no vector is it will do a X by plus a Y. Into the component of vector around where taxes That's competitive belong to buy access so we can write it as six that's 90. Similarly for Victory we can. Right 78 minus he's yet. Mhm. Better see do I? Yes do I minus 60 minus 60. No or we have the plane picked up a policy. What question we have to find victor. A plus victory. Yeah victor is 68 plus 90. And vector B is seven. I minus treated this seven party minus is it? No you will solve reporter. So six plus 78 that will give 39 Plus 9 -6 Yep We will see the jet of 9 -3. It will be six gee. So the magnitude of vector A plus. Sorry we have to find a component of victory. It was B. So here X. Component of vector A X. Component of vector A plus B is equal to 13. And why the component of vector A plus victor V is equal to six. No good question B. We have to find A minus closing victor A minus put into victory. C. No Victor 86 I that's mine, jay -2 into Victor. C. is 08 minus 60. No further solving this. I I didn't take the item one. So here's a zero plus 6 76 plus nine minus 60 year minus minus plus. And it will be +99 J. 19 yet and two in 20. It will be zero and minus two to minus six. That will give plus we're into. Yeah So we can write six I plus 25 to the so x. component of victor A minus bluesy is equal to six. And boy component of vector A minus pussy is 25. No we will solve it for victor C. But the bar seat we have to find victor A B minus vector C. So value of victory. Value of Victor A six I bless 90 68 plus 90 and value of victor beads. Stephen I my guest DJ minus vector C zero minus 60. So they will take items a calm place and jaden on that another place. So six plus seven plus zero 46 plus seven minus zero into fight left. Nine minus three Plus 6-8 now six plus seven. That is equal to 13. I yes nine minus three Uh plus six. So that is 20 plus 20. So the magnitude of vector A plus B. My legacy is equal to 13. It is along the x axis. And male the victim. If this victor b minus victor, C. And uncle why you access that is equal to. Well now they've been solved for be part or depart party we have to find victor. A Plus one point to victory minus three into victor. See now substituting the value of a victor, victor victor. See so here A six I last nine J plus one by two, vector V is seven. I minus D. J -3 into vectors is zero, I minus 60. No further solving this. 68 Plus seven x 2. Can do I zero into I. Okay 40 nine inclusion -3.2 into they. Yes. Well to 60. No taking I common in first time. So here in uh in this so here six plus seven by two is 3.5 into. I am plus here we will take a common Then it will be 9 -3 by two it makes 1.5. Yes 18. No further solving this six plus 3.5 that is 9.52 I Yes 9 -1.5. That is 7.5 plus 18. So 7.5 plus 18. It believed 20.25 point five in two days. So X. Component of a plus one by two B minus crazy A plus one by Toby. My next Crazy X component is equal to 9.5 and y component of victor A plus one x 2 victory. My next three and 2 victors. It will you. 25.5. That was like tradition to this question. Thank you.

Here The magnitude of Vector is 10. Which of the following could be confident of a So we know that vector is equal to X. I kept Plus, if I Jacob and magnitude is a call to on the road Ex confident square Plus, are you confident? Square? Now we check our option. A option is we have given a X and A Y in option. Hey, we have given five and five so we will use hit and trial method. So for this magnitude will be called 205 square plus five square. So this will be called to and the road 50 That means it is five or two Magnitude is five or two but we have given that magnitude It magnitude is equal to 10. So our options a will not be right Answer like this An option we we have given or X component is six and why component is eight 60 square plus 80 square. This is equal to 36 plus 64. It is equal to 10 so it can be ever answered. Now, in option C, we have given Yeah, X is seven and Eva is nine, seven and nine. So magnitude is seven squared plus nine square. It is again not equal to 10 and an option d We have given 10 and 10. So again, magnitude will be 10 x squared plus 10 square which is equal to 10 route to again. It is not equal to 10. So our option we will be right option because in in this option, the magnitude is equal to 10. So option B X is equal to six and ever is equal to eight will be right Option. Thank you.
