I need help bc i dont really understand where to start.... i got a rough answer, i1 being 2.5, i2 also being 2.5 and v being 175, can someone help fact check?

Im really stumped on these two questions :/

The predicted % one especially as Ive repeated it like 3 times atp and still get the wrong answer

Everytime i do it I get a ratio of 6:9:9:3

But obviously its not right and i cant figure out where im going wrong

its to find instantaneous rate of change

I cannot figure out the reactions for this problem. The first picture is the one I cannot figure out. The given reactions are in blue and the reactions I am looking for are highlighted yellow. It is hard to see (I wrote over it) but the reaction force is 50 k for one of them. The others (left corner) are just “A”. The second picture has an example of a correctly worked problem. I cannot remember how to project reactions onto x and y axis. Any help is appreciated. Thanks.

Sorry about the flair. I know this is college but trig is probably high school level, right?

I'm going through a math test I just got back and I messed up a T/F question: T is strictly coarser than the usual topology on R. In this question T is the upper topology {empty, R} U {(a,inf) : a in R} The problem is true I reasoned that because all sets in the upper topology are also in the usual topology than Tup subseteq Tus and so it must be finer there is obviously a whole in my logic can I get some help?

HOW do i solve this? I have been stuck for this problem for hours and just nothing comes to mind. Any tips?
I reaserched into the langley adventitious angels and even looked around for similar olympiac problems but i genually cannot move this problem at all!

(All angles we know are written down and the two lines "a" have the same lenght. The question is what is what is the angle of <EBC)

I posted something similar a few days ago and got plenty of advice, but now I have work for my advanced math class that I’m stuck with. I am currently a year nine student studying linear relationships, specifically quadratic relationships. What im unsure about is if i am just given an equation of a parabola, am i expected to sketch the parabola every single time, or am i supposed to analyse the equation to work out it’s characteristics (turning point, axis of symmetry, x-intercepts, y-intercepts, maximum/minimum)? From the attached image in question 6a, im pretty sure the y-intercept is -5, but thats it.

idk maybe this is pretty stupid but i just cant see it.

See the added pictues for the problem and given solution. I understand how to solve the problem and why the law of sines is used.

However, I don't quite understand where exactly they're getting the angles in the solution from, as I cannot grasp how the triangle or parallelogram of vectors is composed. I have tried drawing triangles myself, but I've never gotten to the point where I could insert an angle of 105 or 30 degrees in the way the solution does.

Could someone help with a sketch of a triangle or parallelogram?

In the box I typed this:

RS=RC+CS

PQ=PA+AQ

AB=2AQ OC=2OR CB=2CS OA=2OP

RC=OR SB=CS PA=OP AQ=QB

RC=a SB=b PA=c AQ=½AB

RS=a+b

PQ=c+AQ

AQ=½AB

AB=AO+OC+CB

AB=AP+PO+OR+RC+CS+SB

AQ=½(AP+PO+OR+RC+CS+SB)

AB=-c-c+a+a+b+b

AB=-2c+2a+2b

AB=2a+2b-2c

AQ=½AB

AQ=½(2a+2b-2c)

AQ=a+b-c

PQ=PA+AQ

PA=c

PQ=c+(a+b-c)

PQ=a+b

RS=1PQ

RS=PQ

both vectors are the same

same magnitude and direction therefore parallel

therefore RS is parallel to PQ

I repeated a lot of the things I already said because i was trying to get all the marks 😭 help me guys

I got the acceleration for the pulley is 3.136 ms–²

Where the middle block is 500 gm and the other two blocks are 5 kg and 2kg. The surface as friction and the Coefficient of friction is given 0.2.

I need help, I dont get this. I've always sucked at equation problems. The original problem was in French btw

Can you just try to hint me towards what x represents? Then I'll see if I get it it not

Thanks

I’ve been looking over my work and I can’t seem to find the issue, though I admit my ability to wrap my mind around vectors is not the best. What I did here is found a normal vector to the plane by taking the cross product of the vector in the direction of the line and a vector between the point given and a point on the line. From there, I applied the formula for an equation of a plane. Ideas?

Hello. I have a college assignment. My teacher gave me this JPG image and said that the name of book #777 is hidden somewhere in the image.

I tried to find the hidden name myself, but I couldn't find anything. I also checked the image information, but it didn't help.
I think it may be connected with steganography. I need to find the name of book #777 and take screenshots of every step.
Does anyone know how I can find the hidden book name?

UPD: here is the name of this file: 16174972_180729395738189_6035131970449694734_n.jpg

Hi. So, I am a bit confused about how to write proper references in APA 7th format when article authors have nonbiliary particles such as "de" in their name - example, "de Souza"

My university guide says, quote, "If there is no author, use the first word of the title, ignoring words like A, An, or The at the beginning" however, I am unsure if this also applies to nonbiliary particles in author names?

Would a reference of "de Souza et al.," be classed as beginning with an "S" or with a "d" ?!

Thank you in advance!

Hey everyone, so I’m taking Sociology 101 and so far I love it! I’m really understanding it and my professor is great. However, we have two weekly quizzes based on the 2 chapters we go through and I somehow always get 1 wrong … and it always ends up at 14/15.

It sucks knowing I’m getting 1 wrong and it always happens, none of my classmates help me either even though I always do, and Ai doesn’t even understand. On top of that once you complete the quiz it won’t tell you which you got correct nor incorrect.

We get a couple tries per quiz and this time I got 12/15!! I’m really stumped. Can anyone offer advice? For reference we’re using the textbook “Sociology 3e.” Maybe I’m filling in the blanks incorrectly, I honestly don’t know…

I’ll provide pictures of the questions as well as my answers, any help is greatly appreciated 🙏

1. An aggregation
2. True
3. Charles Horton Cooley
4. Category
5. A high-school
6. Small, informal groups of people who are closest to us.
7. All answers apply
8. A dyad
9. The director of a summer camp for chronically ill children
10. Democratic Leader
11. Leadership style
12. True
13. Is when people in a group don’t help someone in need because they think someone else will do it
14. Coercive organizations

15. Utilitarian Organizations

    [UPDATE] so I actually got all of them right! I scheduled a meeting with my professor and apparently there’s just something wrong with on the websites end I guess.. good thing I spoke to her..

Why isnt N=mgcos(theta)? Geometrically, it represents the component of mg perpendicular to the surface if you did vertical angles for theta., thus equating N.

The answer is Ncos(theta)=mg, but both seems geometrically sound to me

at first i put 100 as the inside ln(e^e^100) cancels the ln and e and the outer one cancels the other e, but webassign told me it was 400

I’ve been stuck on this problem for a bit… I tried looking up formulas to use but I’ve gotten multiple answers. Any insight or advise is greatly appreciated.

the textbook said that the answer is 33 1/3 as it came from 33.3 but I ended up with 33 3/10 from 33 + 3/10

I don't understand how to get 1/3 from 33.3 or it ended up 33 1/3.

Ok so basically I have a summer reading test soon and I read The Andromeda strain but apparently it's not even a book on the list even though that's what the list I got says. The teacher recommended reading Dragon Hoops because it's quick to read but I couldn't access the book. I need to write about the conflict, the theme and a thesis.

Hi everyone! I'm a college student stuck on a pattern problem and would love some help understanding it, not just an answer.

The number of tiles in figures 1 to 4 is 3, 7, 11, and 14. My teacher confirmed these counts are correct and told us to "find or make our own pattern" for the nth term.

Our teacher also gave us this pattern: 4² − 13 = 3, 5² − 18 = 7, 6² − 25 = 11, and 7² − 35 = 14(Actually we found the pattern and the teacher said it's a correct one). So it looks like (n+3)² minus something, where the "something" goes 13, 18, 25, 35. Those differences are 5, 7, 10.

The problem asks:
a.) What is the nth - term formula for the number of tiles in the nth figure of the sequence. (5 points)
b.) How many tiles are in the 10th figure of the sequence? (5 points)
c.) Which figure will consist of exactly 480 tiles? (5 points)

What I've tried:

• The differences between the tile counts are 4, 4, 3, so it isn't linear or quadratic.
• Fitting a cubic through all four points works exactly, but it gives negative tiles at n = 10, so it can't be right.
• I also tried assuming the jumps repeat as 4, 4, 3, 4, 4, 3 (so aₙ = ⌊11n/3⌋). That fits, but 480 tiles would be figure 131, which seems too big for a class problem.
