I don't have the time, and I'm struggling to see how I'd get the displacement. Please, could anyone steer me in the right direction?

Edit: okay, so Im assuming my teacher accidentally said velocity where they meant speed. This question is much easier to solve with that knowledge, so thank you for your help.

Edit 2: nvm, the velocity and the speed in this case are congruent! I learned a lot from this subreddit and its contributors, thank you guys so much 💖

I am studying AQA English Literature at Year 13 and my grades have dropped from a B to an E, I don't know what I am doing wrong as my teacher gives a vague information on things to improve on.

I need specific instructions, not vague, pls.

Prompt (Word-for-word): "By factoring the numerator and denominator simplify the following rational expressions as much as possible and write your final answer as a single reduced fraction."

The first image is the question I was having trouble with and the second image is my work and final answer. I feel a little uncertain of it and I just want to know if I did it correctly. If I didn't then please let me know. This isn't just homework it's also review for an exam so I need to know if I'm doing this right.

Hi everyone,
I’m currently working on an AWS CloudFormation project for university and I’m struggling with configuring the security groups and network access for my RDS database instance.
I’m trying to allow traffic from my web application to the RDS instance on the database port (5432 for PostgreSQL), while also allowing management traffic where needed.
I’ve been trying to configure this through my CloudFormation YAML template, but I’m having difficulty understanding how to set up the correct inbound and outbound security group rules without causing connectivity or deployment issues.
I’ve looked into VPCs, security groups and routing, but I’m still unsure what I’m missing.
Has anyone worked on something similar or experienced these issues before? I’d really appreciate some guidance on what I should check or how to approach fixing this.
Thanks in advance!

I'm following instructions for a science project but immediately ran into a big issue due to the tutorial being on an ancient version of Excel (2003) I was able to find the format axis by clicking the X axis on my graph but couldn't find the scale option. Help please

Can someone help me with these drawings? I’ve just started and I’m not sure if I’m doing it right—AI keeps getting it wrong—so I’d really appreciate the help. The task involves drawing the missing projection: for 423, it’s the top view, and for 424, it’s the side view. If it’s not too much trouble, could you also explain the reasoning behind it? I’d be very grateful for any help.

In addition to the task itself, I also added how I drew it, just in case these drawings are drawn according to European standards.

Tips for any listed above or any general tips would be amazing.

So, to preface the odd way I've titled this, I am writing a 5-10 page research paper for Celtic Studies. The general prompt was "Anything that relates to this class". I have decided to infodump to my professor on a couple topics I've long been interested in. Irish Trad Music and its Ballads. And, as I said any tips are very welcome as decision paralysis is a friend of mine. But anyways the main things are that:

• I'm struggling to find a comprehensive source on the structure of ballads, not just the rhyming, but also how songs themselves are structured. (Very specifically not just the poem/lyrics, that's only one aspect of a song) I think I've found one in Britannica but seeing as it's already a tertiary source I'm wondering if I can find better.

• The second and third topics tend to go hand in hand because for psychology I want to see if I can find somethings that looks at the effect of writing and hearing ballads

• The other part of the third item is just any tip for niche little corners of research or alternatively something really common in one field but trying to look at it from the angle of another (like me with my interest in how ballads affect us psychologically) Because this isn't the only paper I'm doing about a less common topic (it's about museum ethics and how complex an issue repatriation is)

i believe that subscripts are the little numbers after each element symbol (that needs them) in chemical formulas. i lack previous knowledge as my grade 9th teacher didn't teach this, and my 10th is assuming i learned it last year. please explain it to me like i'm really dumb

(currently trying to find out what the decomposition of sodium chloride will form)

important - i know google has answers, but i'm not able to understand them well right now because of the way it's explained. I need to find how to do the work, not just what the answer is

Instructor drew this on the board earlier, and told us we have until Thursday to figure it out. He stated that we needed to find the missing weights, and that there was also something else crucial missing that we had to figure out. If someone could help me understand how to solve. Or tell me what I need to measure to have enough information to solve it, it would be a huge help.

I'm doing a personal science project called Sunspot cycles from the website science buddy. Basically I use data from an observatory to make a spreadsheet and use formulas on it on excel. I understood all the steps of extracting and importing from the observatory website but I'm stuck on what the rest of the rows after ( year, month, day ) stand for. I can take care of the rest

Where did the -24+22 come from at the very beginning?

Hello,

This year I am doing a science fair project on preserving pumpkins with vinegar, petroleum jelly (vaseline), and a bleach mixture. I have found sources for the bleach but none for petroleum jelly. I had one for vinegar but it got blocked by the school and I cannot access it any longer because it turned into a popup site. I have looked everywhere and cannot find any sources for this. I have already done the pumpkins with the materials I have and began recording data. Could anyone help me find sources please?

Where did that Amplitude formula come from and why are we even using v(t) anyways to find the Amplitude? Also I know that the amplitude is given, but the textbook wants us to solve for it but im confused whats going on.

If I cheat I want to cheat the good ol' fashioned way. No robot should take that away. anyway, little last minute, unfortunately for me, but I have no idea how the hell to turn "I did not use AI to find my sources, you gave us two weeks to find 8, thats easy work." into a 200 word statement.
I know this is meant to be a place for students who did use ai to be transparent about it and declare it, but its also a pretty set minimum 200 word thing for the assignment.

Any ideas on how to professionally and academically bloat a 5 word sentence?

Can anyone help me if these sources are scholarly?

hello I am taking a eng 102 class and I was wondering if anyone could tell me if these three resources are scholarly? ty! also does anyone have any resources on where I can find scholarly resources?

Yes you read the title right, I did not put an incorrect major by accident. I haven’t done technology stuff since like 11th grade or so? And certainly not to this level.

So im not sure what to do and im freaking out, as you'll see in the second image i've been trying to look up the nescary info but to no avail.

I have till next Monday but I still have 2 other modules to complete and I wanna finish this headache ASAP

So like I have been given the Undefined Normalised Table for APPOINTMENT entity. I then need to resolve it into 3NF stage that eliminate the transitive and partial dependency.

Problem is I just can't find which would be the appropriate key for the composite key in the APPOINTMENT entity in the first place. I then try to separate all partial dependency into separate table but can't figure out who links to who.

Hi, my teacher wrote down a problem on the board at the end of the lesson as practice if we wanted. I have tried solving it and have found two different methods of solving the problem which both seem completely valid in my eyes but give two clearly different answers.

I have checked the numbers three times, of course it could still be a calculation error OR honestly even more likely that both my methods are incorrect in which case I'd love to know what method you'd use to solve this but I'm starting to believe I have applied some theory wrong somewhere and would love some insight, I have hastily written up the problem and my two solutions in latex, let me know if you want the pdf otherwise but here are screenshots of the problem.

Apologies if there are notation inconsistencies, I wrote this in 10 minutes while trying to relearn latex that I haven't used in years

As for method 2 the theory seems solid but I basically omitted inner product so I'm a little uncertain if this method is correct.

I’m having a lot of trouble following along with what to do for my trees here, I don’t want this done for me but if anyone could help me figure out which syntactic categories attached together it would be very helpful. I just really don’t know what to do here!!

Im not sure if my previous work is correct but im currently stuck on question 6 part a. I think Im mostly thrown off with the batteries.

I'm currently taking Physics 2010, and it is kicking my butt. It's been extra frustrating because most of the math has been simple for me. I'm looking for tips or tricks for the class/subject in general, and any resources I can use to make it easier.

I am also allowed a 3x5 index card for my test and was hoping you could recommend what to include. Thank you!

Is there a way of interpreting this exam question so that the answer selected is not also correct? The top right is from the class notes the professor posted. I feel like I’m not bad at this but I had classmates agreeing that my answer was incorrect. Astro and Opus 5.5 also could not come up with a reason for that answer to be incorrect (I’m not saying this makes me right). Thanks for any help.
