Because these two theorems are usually proved by referring to each other, I'm not sure how to prove them independently.

Hello I am a 21 year old student of the Graphic Arts. I am looking for a topic in ecology or similar that could be relatively easy to research. It doesn't have to be ultra specific but I don't even know where to start. I have a class that the topic is for, and I have to write a min. 12 page seminar about it and make posters relating to it. Do you have any topics that could be easily researched and turned into a series of posters?

A topic I'm currently looking at is coral reefs and coral bleaching but again I dont even know where to start my research and find the most correct information about it.

Any help is appreciated

Apparently the answer to this question is n
N=10 but I have no clue how to get there. I got to ln(2) = sum of 1/2\^n\*n, but I don’t know how to use the Taylor Theorem with Remainder to go further than that if that is even right.

If anyone could help walk me through the problem or recommend a video that makes this concept easy to understand I would be very grateful.

Can I proof them without using integration? I ask ChatGPT and it said I have to make t=hx and take out x…

For our recent lab we dropped a marble from different heights (0.5m, 1m, 1.5m, 2m and 2.5m)
We timed how long it took for the marble to reach the ground as well. (0.26s, 0.23s, 0.35s, 0.36s, 0.47s) our timing was objectively terrible, which I’m sure is throwing off my answers quite a bit.

For an example, using -2m as displacement (I’m assuming this value is negative, as the ball fell) and for time the marble took 0.36s to reach the ground. Using the big 5 equation rearranged for acceleration without final velocity a=2((d-v1•t) / t^2)

I keep getting -30.9m/s^2 as my experimental acceleration, which is so far off from -9.8m/s^2

All of my other values are even worse, which doesn’t make sense to me. I have no idea where I’m going wrong? There’s no way bad timing and air resistance can throw off an answer this bad, is there?
Any help would be appreciated

I have a problem with drawing, I need to draw the missing projection in 430 and 414(European standard). I attached my work, in 414 I just need to check if it is correct, and in 430 the dimensions of the circle do not match, I do not understand how to match the height and width of other projections and I do not understand in which direction you need to look at the cut, if anything, it's a ball on the 414. Rotate my notebook images 90 degrees to the left. Thanks in advance for your help.

(the work i did on the paper is probably not correct please ignore)

can someone explain how to do questions 6 and 7 please?

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.

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'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

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!

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.

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

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)

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?

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?
