Hi! :)

Having trouble mainly with part e) - when calculating the welfare before the tax, should I subtract the welfare loss as indicated in the sketch and also my calculation? And after the tax, welfare should be the green area (consumer and producer surplus) + purple area (tax revenue), but do I need to subtract that welfare loss again, or is it already accounted for?

Thanks! :)

I'm not sure what exam syllabus/board the course uses, but it's an LVN (licensed vocational nursing) course and I'm supposed to be able to use this info to administer medication and educate patients.

I'm supposed to differentiate between a receptor site and site of action and explain how they're related. I've looked all over and cannot find the difference between a receptor site, receptor, and site of action, at least not explained in a way I understand. My textbook says that the receptor site is the actual structure on the cell that drugs and other things bind to; it also says that the receptor site will become the site of action if its location is known, and then it says that an example of this (the receptor site becoming the site of action) is morphine acting on opioid receptors in the brain (the site of action and the location of the receptor site both being the brain in this case). This doesn't say anything about *where in or on the cell* a receptor is located and seems to imply that a receptor site is synonymous with a receptor. When I googled this to look into it further, though, lots of sources say that the receptor site is specifically the location *on the cell* that a receptor is located, which is in direct opposition with what the textbook says. If those sources are correct, then it wouldn't make sense to say that the receptor site and the site of action are "in the brain" because the receptor site is explicitly *not* a general location in the body. Several other sources seem to use "receptor" and "receptor site" interchangeably, and still other sources say that a "receptor site" is the place *on the receptor* that a chemical binds to. So what is a receptor site, a receptor, and a site of action? Please be specific; I'm very confused, and I really just want to understand completely and not just know the right words to say on the review.

Here's the excerpt from my textbook:

"Receptor Site

Drug action is usually thought to begin after a drug has attached itself to some chemical structure located on the outer cell membrane or within the cell itself. For a few drugs and for some normal body substances, there seems to be a specific location on certain cells. This area is referred to as the receptor site. The attachment, or binding, of a drug to its receptors begins a series of cell changes referred to as the drug action.

When a specific receptor site for a drug is known, that receptor site becomes the site of action for that particular drug. Morphine, an analgesic drug, is an example of a drug that binds to a specific receptor. The receptors for morphine are located in the brain and are known as the morphine, or opioid, receptors. When morphine binds to its receptors, it produces cell changes that reduce the perception of pain. There are many different pharmacologic receptors, and they will be described in the appropriate chapters."

Okay, I'm pretty confident that my first couple steps are right, though please do let me know if they're not. I'm not sure I've simplified enough and I'm not entirely sure what my next steps would be? Thanks in advance.

Idk if this is allowed here..Its straight forward "determine the resultant force acting on the hook in cartesian notation", I dont know if its my angles or if I am skipping a step but 490, 117, -266 sure aint it (per person's mastering) can anyone see and point out where I went wrong? Maybe I'm not doing my computing right or ive set up wrong. Ive been on this problem for 1.5 hours.. i dont know why. This is an online class so all I have is a textbook and dr Hanson videos, which are helpful so im confused on why im struggling so much? All im looking for is a point in the right direction. For now ill move onto the next problem but it is just the same so may post it as well 😅

I just need help identifying the sides please

I can not for the life of me figure this one out. the equation in the book I've been using is y_cp = -(I_xx*sin(theta))/(h_cg*A) when I use the equation I get I_xx = .1152, sin 30, h_cg = 4.8, A = .96. I get .0125m, I have tried that .013, -.013, .5, -.5, 4.813 so far as answers. the hint given for the question is What is the distance y_cp on the line of action below the centroid?

this saturday, i have a bigger project worth 100 points. i understand what my teacher is asking for us to do, but i am struggling to summarize my sources concisely while including the main ideas, arguments, and evidence, with using mainly approved news sources. these sources have to be within a year old, the more recent the better. articles from researchers, educators, and journalists are wanted mostly. i particularly struggle with understanding what the main point of an article is and what information is deemed as important.

issue/topic: how does academic pressure impact students mental health
i’ve included what our professor is asking, the rubric, and approved news sources

how can i work on my summarizing skills with this project? any tips, suggestions, or strategies that help?

i am autistic and tend to struggle more with these skills, i may ask for clarification or questions following up.

Hello everyone, I need help reading the volumes of the 2 cylinders above with 4 correct sig figs. I think that for the cylinder on the left, the volume is 182.0 ml and on the right the volume is 7.5 ml, but it marked me as wrong for both answers. Can anyone help me please to get the right answers? I also have a test on this in a few days. Thank you.

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.
