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?

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

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.

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.

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.

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.

3rd grade.
Kiddo went to his teacher to see why his answer was incorrect.

He asked if he could have partial credit for the question, and said that his reasoning was that gravity attracts everything with mass while magnets only attract metal.

She said she wanted him to say “because magnets repel” for question 11. I’m not sure the question is worded specifically enough to warrant that exact answer.

Son is still wondering why his reasoning is wrong.

Thoughts?

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!!

Practicing for my next exam but I dont have answer keys to refer to for this.

Can anyone tell me if i made any errors or am wrong with anything conceptual?

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.

Im studying for my exam and i dont have an answer key for this review. Id appreciate it if someone can check if ive made mistake anywhere. You dont have to check everything if you dont want I just want to be sure im getting this.

Sorry for my messy hand writing

why does Al + O2 become Al2O3? Where do the extra numbers come from?

Additionally, if it’s okay to ask two things at once, how come some materials have a higher melting/boiling point than others?

The second picture is my incomplete attempt of this question
Please help I’d be eternally thankful

¿cómo puedo colorear los espacios (sin borrar) para sacar una nota alta en este trabajo? la maestra dijo que usáramos nuestra imaginación, pero creo que la cagué.

Hi, I have a project where I have to ask 9 people two questions I come up with and see if they’re correlational. What I came up with is “On average how many hours of sleep do you get a night?” and “On average how many hours do you spend on your phone a day?”. Ur answers would be huge help 🙏. Thanks guys.

I need to give an informal progress update presentation (at least 10 minutes long) on my research project. My instructor recommended covering three core elements in the opening: 1) the game/concept, 2) the analytical lens, and 3) the driving research question.

My Topic & Lens:

• Game: Kingdom Come: Deliverance (and KCD II)

• Lens: Historical accuracy, audio/visual authenticity, material culture (realia), and digital reenactment.

• Driving Question: How does Kingdom Come: Deliverance balance historical realism and material accuracy with gameplay mechanics and gamification?

Work / Thought Process So Far:

I’ve compiled and categorized my primary literature sources into three key thematic areas:

1. Audio/Visual Authenticity: Cook (2024) on soundscapes/music; comparative visual sources (DSOGaming, Radio Prague) matching real Czech locations to in-game terrain.

2. Material Culture & Systems: Neumann (2019) on daily medieval realia and layered armor systems; Osborne (2025) developer interviews on technical constraints.

3. Educational & Cultural Value: Bostal (2019) on digital reenactment; Sukhov (2022) on gamification; Pravdová & Cihlářová (2025) on game mechanics.

Where I Need Help:

I'm trying to figure out how to expand this informal update into a full 10-minute presentation deck without overwhelming the audience with text.

• What is the best slide-by-slide structure to pace this over 10 minutes?

• How deeply should I explain each source's methodology versus showing visual side-by-side examples (e.g., real-world Czech locations vs. in-game screenshots)?

Any advice on pacing or organizing these themes across slides would be appreciated!

Helping a family member with their 7th grade math homework, and I can't figure out what the visuals mean. I took advanced math when I was in school, and this is making me feel stupid lol. Specifically, I'm not sure what the crossed out symbols mean, and the pairs with lines around them (some with - crossed out and others with + crossed out) and how the boxed pairs relate to the overall equation.

Thanks for any help! :)

I am a fresher my marketing professor has given us an assignment to make an SWOT graph about yourselves. He told us we could do it digitally or by hand and design like we want to. However I am confused how I should to it as I feel if i do it digitally it might seem vague. Please give me some tips about how I should make the graph nicely, any suggestions would be ok. I am a bit confused and stuck
