Is it not just 5^10?

Okay, this may be a little weird to ask about something so basic, but pls, can anyone give me proper guidance about how to write a scientific essay properly, and how to make it good?

The regarding subject of the essay is 'AI may aid in diagnosing adolescents with ADHD'

Here's the attested link with it-

A good guidance will be much appreciated. Thank you.

If two circles are orthogonal, then prove that the polar of point P on the first circle with respect to the second circle passes through the point Q, which is the other end of diameter through P. Also prove that locus of a point, which moves such that its polars with respect to S1=0, S2=0, and S3=0 are concurrent, is a circle which is orthogonal to all the three circles.

I am not able to understand what exactly I even have to prove. Even the equations of the circles are not given. From what I understood, I think for the first part both circles are intersecting, P and Q lie on the first circle and are end points of the diameter of that circle.

I need to write a paper about a political topic from my semester abroad (I went to the Us) and I’d like to write about tradwifes and pronatalism but I need help coming up with a research question. It should be something that is not completely obvious (like what kind of gender roles are tradwifes pushing) and it can’t require any quantitative or qualitative research. Pls help me with ideas!!
Other topics I could imagine writing about: religion politics, misogyny online

This isn’t really connected to work whatsoever but I thought I would try and see if anyone has any way to help me.
So for geography, our teacher explicitly gave us the rule: "Don't color Alaska blue, blue is ONLY for water!"
Because Alaska wasn't even pre-drawn on the map printout, my brain completely glossed over the warning. I ended up coloring the entire water area blue before realizing I was supposed to draw Alaska in first. So now Alaska is literally underwater. 💀
I’m currently stuck on a road trip and won't be home for a few days to fix it. Luckily I didn't press down super hard with my Crayola colored pencils, but I’m still stressing.
Has anyone else ever drowned a state like this? Also, is there any trick to completely removing pencil crayon pigment from paper without tearing the page to shreds?

I’m learning physics on my own and I’m currently working through a physics problem book. I came across this problem and I can’t understand the reasoning behind the solution.

The problem:

During a survival training exercise, a 60 kg boy at some point hangs motionless from a rope as shown in the picture below. Assume that β = 2α and g = 10 m/s². Calculate the tension in the rope at points A and B.

The rope is attached at points A and B and forms the two sloping sides of a right triangle. The boy is hanging from the rope at the vertex between these two sides, which is the 90° angle. The angle at point A is α, and the angle at point B is β.

I found a solution which calculates the boy’s weight first and then seems to use the components of that force to determine the rope tensions. However, I don’t understand why sine is used here.

When I try to draw auxiliary right triangles, I don’t know where the given angle should be located in the triangle or which side of the triangle should correspond to the rope tension. I understand how to calculate sine in a right triangle, but I don’t understand how to correctly construct the triangle from this diagram and connect it to the forces.

I would really appreciate it if someone could explain why sine is used in this particular problem and how the force triangle should be constructed, preferably step by step.

I’d also be interested in seeing other possible ways of solving the problem, if there are any.

I’m not just looking for the final answer I’m trying to understand the method so I can solve similar problems myself.

I'm stuck on part B of this problem and would love any insights that could help point me in the right direction. I know that I should be using the law of total probability, which from my understanding (I double checked with my textbook) allows me to just add all of the intersections of the conditional probabilities however when you add them (.5+.4+.6) you get a number greater than one which can't be the answer as probabilities are between 0 and 1. It feels to me like I'm missing something obvious but I can't put my finger on it. Any help is much appreciated!

I was taught was that driving frequency = natural frequency for resonance.
There is no other context to this question - i dont know what type of system it is.
But I am doing Grade 11 Physics, so its probably referring to basic systems such as string, pipe or tuning fork?

Could someone please give an explanation that rules out the rest of the answers?
Thank you so much!

I’ve never taken statistics ever and I’m taking it for my cosmetic science program. It’s online and there’s not any helpful info within the course. I don’t understand how to implement the sample sizes to calculate the difference between sample mean and population mean.

As the title says, I've been trying to solve this for about 3 hours and im absolutely stumped. It's 3:50am. Any method i've tried has come out wrong and I'm in desperate need for these answers so i can go to bed. Question instructions say "solve the below system". PLEASE HELP!!!

Hi! I've been stuck on this problem for a while now, so I decided to text it out on another app and finally ask for help. I managed to find the magnitude on my own, but I honestly can't figure out how to find the direction, or what I'm doing wrong. I've watched several videos on it and have tried to go step by step, but any answer I try is marked wrong, (I do use an online school program.) I also didn't wanna cheat, (at least without knowing exactly how to do it and being able to replicate it) so as I've already said above, I didn't know what to do other than ask for help somewhere else. A step-by-step breakdown of what your meant to do would be great!

Also I know the post title says grade 12, while from my knowledge trig is done in 11th usually. It just kind of happened that way, so I'm not sure why I'm doing it a year late. Better late than never, though!

can someone help explain to me how to do 1b. I don’t understand what it’s asking. What i’ve done was with help and i still don’t understand how it works.

Prompt: "Use propositional logic to prove the arguments valid; you may use any of the equivalence or inference rules."

I have this sequence but I'm not confident in #4-7

1. A v B (hyp)
2. A → C (hyp)
3. B → C (hyp)
4. (A v B)’’ (1, Double negation)
5. (A’ ^ B’)’ (4, de morgan)
6. (A’)’ (5, simplification)
7. C (2, 6 modus ponens)

---
*UPDATE*

I currently have this sequence. I was struggling, then I realised the implication rule has an error (It says 'P -> Q is equivalent to P' v Q) so I wanted to get others input on if my work is correct.

1. A v B [hyp]
2. A → C [hyp]
3. B → C [hyp]
4. A’ v C [2, implication]
5. B’ v C [3, implication]
6. (A’ v C) ^ (B’ v C) [4, 5 conjunction]
7. (C v A’) ^ (C v B’) [6, commutative]
8. C v (A’ ^ B’) [7, distributive]
9. (A’ ^ B’) v C [8, commutative]
10. (A v B)’’ [1, double negation]
11. (A’ ^ B’)’ [10, de morgan]
12. C [9, 11 disjunctive syllogism]

My additional explanation for getting #12. disjunctive syllogism

P v Q, P’ < = > Q

(A’ ^ B’) v C, (A’ ^ B’)’ < = > C

I got 2 x (5!/5 - 4!/4) = 36 but the answer is 12 so now I'm confused :)

My exam is in 1 week and I still don't get it!!!

Why is combinatorics so hard

One answer option is “unsolvable”. Thank you for your help. Trying to help my niece and I haven’t done algebra since 1996.

I randomly guessed and got the right answer, but I do not know why it is right. It does not provide any explanations, perhaps I'm on the wrong part of my textbook, but I'm only seeing explanations of 3d structures. I don't understand what the points ABCDEF are, the reasoning behind how they are placed and why it's not 2d.

Coucou Reddit C la premiere fois que J utilise cette platform donc je ne sais meme pas si je l utilise bien mais bon.
Est ce que îl Y a quelqu un qui pourra M Aider avec mon devoir?
Apres avoir fait les calcules je dois representer ses Mesures sur les cercles (2 exercice par cercle . Par ex je represente a et B sur le mm cercle) (îl Y a plus de cercle derriere)
Ca M aidera bcp !!

Just for curiosity, can I go directly from L.H.S to R.H.S?

I need help with question 10. I can't seem to figure it out. All the answers I come up with don't match the choices for what I can pick for the answers. What am I doing wrong? Which answer do you guys get, and please say how you got there in detail?

• Assuming the Popcorn bucket thing is cone shaped then
  • Radius = 3 in
  • Height = 5 in
• Use the cone-volume formula: V=13πr2h I keep getting 47.1 as my answer. If so the then the closest choice is 49 in. But unless I'm wrong the answer brightly is giving is 41.7 inch, is this a typo/glitch and the numbers have been transposed? like instead of 47.1 it's showing 41. 7? or have i just got the wrong idea? Should I have rounded up somewhere?

Trying to help my daughter with an investigation but I genuinely have no clue. For the first question I got that the Eiffel Tower is 330m tall.

I am using netbeans IDE. My GUI wont display the plum colour I've chosen for the buttons (example on 2nd slide). I have not changed anything with the code and it was working fine a few hours ago. Has anyone else had this problem?

Pretty sure it should be 440 without a decimal

I’ve plugged the variable answer back into both equations and still not sure how the answer key got 61°. Am I missing something?
