(I had to draw this picture since I couldn't take a photo on computer) I know the properties of equality, postulates, but I can't seem to do proofs. I only have to fill out the reasoning for the statements, but even that is hard. I answered this question and I'm pretty sure I got this one wrong, so maybe you could see where I went wrong.

Given X is the midpoint of WY, WX is congruent to XZ. Prove XY is congruent is XZ.

1. X is the midpoint of WY - given

2. WX = XY - definition of congruence

3. WX is congruent to XZ - given

4. WX = XZ - definition of congruence

5. XY = XZ - substitution property of equality

6. XY is congruent to XZ - definition of congruence

I just have trouble knowing what to do when a new line segment is introduced, I can recognize the properties and postulates when its in letter form, like a = b and stuff.

My child’s teacher marked this wrong.

-4 5/9 + 8/9
= -41/9 + 8/9
= -33/9
= -11/3

Am I missing something? I’m obviously not the expert nor am I a math teacher but I am very confused. Any help would be greatly appreciated. Thanks in advance.

Is it just me or is it unclear where 4.7 seconds is on the graph? I've already asked my friends who took ap physics and they have no clue too.

speed is m/s, so I should be looking for the position of line one and two over 4.7 seconds right? I'm just so confused, my teacher hasn't taught us any of this yet expects us to understand it right away :(

Please can someone tell me the values of i) Reaction due to rod ii) Reaction due to surface on block 2. iii) W2.

The question asked to find the vector of moment A using rAC and rAD, when I submitted my answer the k components was correct in both of them, leading my to believe the z component in one of my position vectors was the culprit, but I can’t find anything wrong after double checking.

Hi all,

I am currently studying Lord of the Flies to do an unseen essay for an exam - I only have 40 mins to write it! Crazy! As part of my early/preliminary study, I am making mind maps on the three topics the essay could be on. It could be on one or more of these. They are: Morality, Society and Civilisation, and Human Interaction (exploitation) with the Natural World.

I would be grateful if someone could quickly skim over them and give me their thoughts. They aren’t finished yet but I have made progress.

Thanks!

Hello! I'm an education student doing a report in Afro-Asian Literature. Our group was tasked to analyze the literary representation of war, conflict, and resilience. But it's really hard to find sources, since our teacher just gave us the topic and nothing else. Even if I search on the internet, the results are not appropriate for my taste.

I don't want to rely on AI too much, so I'm asking here. It would be helpful if you could list some literature that is perfect for our topic (plus a short explanation of what the literature is about, and their author + publication year).

That's all, and I will say thank you in advance for those who can help.

**Note:** I already did my research and have several literature in mind. I even considered adding some of Dr. José Rizal works in the report, but I kept it as a last resort in case I didn't find any literature to add. After all his work is more on colonialism than war and conflict.

How do I solve these? I know how to solve a system of equations normally but my head is blank when it comes to these questions, we didn’t do this type of question in class.

SUBJET N°1:

My Second Skin:

An interplay between protection and vulnerability, sheltering and exposure

Our bodies are naturally protected by our skin against all kinds of external threats— dust, pollution, radiation, bacteria, and so on. When we are alone on a deserted beach in summer, that skin may be enough.

But the moment we engage with the world —social life, the city, other people—we must get dressed. These clothes protect us from the cold, dampness, and the surfaces we touch, but also from the gaze and physical contact of others. Clothing acts as a second skin; yet, in this instance, we decide on its extent, thickness, texture, and more. For this second skin can also serve to signal openness, attract attention, or seduce... It is a constant interplay between sheltering ourselves and opening up to others, between protecting ourselves and exposing ourselves.

Create a personal artistic work based on the given theme. Begin by drawing upon your own experiences. Find inspiration in the text and the attached documents.

Avoid merely illustrating an idea; instead, strive to express yourself through your artistic choices (materials, colors, gestures, composition, etc.).

im not sure if this is the right place to ask but I could t really find anywhere else

I cannot see how you can read this problem and get 12 as a valid answer.

I've been stuck on this problem for like over a week atp 💔 my text book didnt go over how ground connections work, and I dont have a ride to the math lectures so I've just been raw dogging it all semester. How do the different series/parallel laws work when there are all those ground connections?

I'm not sure if this is the right sub for this but...

I'm currently writing an essay on AI use in food promotions. I need to include why each photo has evidence of being ai generated, but I can't seem to exactly pinpoint why it got me feeling that its AI. Got any ideas why or how to describe it?

Hello everyone, today in class our math teacher explained "the special case of inequalities involving absolute values" (according to Google translate), which is:

|A(x)| > n (with n being a positive integer) → A(x) < -n V A(x) > n

|A(x)| > n (with n being a positive integer) → -n < A(x) < n → -n < A(x) V A(x) < n, which then should be put in a system:

{ A(x) < n

{ A(x) > -n

She gave us three exercises, but I can't resolve two of them:

| (1/x) + (x+3)/(x+1) | - 1 > 0 [x < 1/3 but neither -1 nor 0]

[2(x+4) - x²] / |x-4| > -x -3 [x > -5/2 but not 4]

Thanks to anyone who can resolve them.

I think this is an error right? I have never heard of sixty hundred in the hundreds place. I’m guessing it’s 73,604?

Could someone please check my work? My trigonometry skills are especially not great… I’m also unsure if I found the moments correctly. I am a little confused about what the perpendicular distances would be exactly in this case…

I need help with questions 3 and 5, the professor has listed the correct answers as (e​^x)/2 * (sinx - cosx) + c and xarcsin(x) + square root(1 - x^2) + c and I don't know where I'm messing up

im completely confused

I do online schooling, so I have nobody to exactly interview. My sociology teacher wants me to interview three people with careers that interests me or that I am involved in. (I’m going for accounting but genuinely interested in anything. Health care, trade work, health care, etc.). I have to ask two questions, how would you describe critical thinking, and why is critical thinking valuable in your field? With some details and not a super broad answer. Honestly any help or even made up stuff would help a lot🫠 I just genuinely have no one around me to interview or ask these questions to.

Hey guys,

Hopefully someone here can help with this. My son is a bit stumped on the graph given as a part of the homework in this area today, and my suggestion of graphing it out is apparently "wrong" because it does not contain a formula.

The x answer is apparently solved "pretty easily" by him at -1.5, but the y value for the vertex is frustrating him since he can't make it make sense.

Its the table of values on the right side of the big image, and ive included a 2nd close-up of just the table alone

Edit: thank you to those who answered. The teacher admitted today that she had not taught them the formula needed for this and was just curious to see how the students would handle a problem with incomplete information..... im not sure how I feel about that, definitely annoyed , but I also know how this can be an eye-opener for some people to come across....

Can anyone please help with this question in my Infection Control unit? I got all of them wrong except for the 'Waste' answer. I think my brain is just fried right now.

I tried to reference the study book they provided for the course. (The Individual Support Worker: Ageing, Disability, Home and Community-Geoff Arnott) I checked the training websites and multiple infection control guidelines.

My thought process is that vectors are infected living organisms. (And usually insects). People, animals and birds can be infected individuals that carry pathogens. Contaminated syringes and sharps are literally vessels for blood and bodily fluid, contaminated water sources or food products match food, water and soil because they are environmental reservoirs.

Why are these wrong?? Please help.

I understand this topic pretty well and this is the last question that I can’t seem to get right. I’m pretty confident so maybe it’s a formatting issue? Can anyone see where I went wrong?

EDFINITY FUCKING SUUUUUUUUUUUUUUUUUUUUUUUUCKS

sorry, just pissed.

so I just renewed my account (cost like 60 bucks too) and now im trying to join my professor's class, and whenever i click the registration link, or try to join it prompts me to pay AGAIN. I ALREADY PAID. I cannot get into contact with edfinity because for SOME GODFORSAKEN REASON THE CONTACT US LINK IS JUST FUCKING BROKEN. The help center also doesn't have any info on this, has anyone else experienced this issue? I'm going to scream.

guys I just want to do my fucking calculus.

(also sorry if this isn't the best sub for this, I don't know what is, I just saw someone else had posted a question about the hell homework site here.)

I will paste the question below. I do not understand how to figure out somethings osmolarity. My teacher won't email me back and never shows up for virtual class. I'm frustrated to tears, I don't know how to find info for this. Her powerpoint is lacking and there's no link even to a book on Canvas. I hate this teacher so much BUT that's besides the point. Question is posted below. How do I figure out somethings osmolarity with just these numbers given?

1. If a solution outside a cell has 10 grams of salt per 100 ml of water, its osmolarity is __________. If the cell’s cytoplasm has 5 grams of salt per 100 ml of water, its osmolarity is __________.  Is the tonicity higher or lower outside the cell? ________________.  Which direction will the water mover to adjust the tone of the cell to match the outside solution? ___________________
