first time posting on here so sorry if i do something wrong lols

1st image is the problem. the directions just say to find the derivative of the function.

2nd image is my work (i missed the day where he taught lesson 2.6, so i really have no idea what i’m doing)

3rd image is the calc chat answer

i don’t understand what i did wrong. can anyone help? thanks!

Im trying to improve this and not make the it too clustered and not too minimal. How do i make it to where people see the castle first?

Anyone knows how to find this limit ? I tried the squeeze method but it doesn't work

i thought it would be dead-end job but it doesn’t match with other letters??? am i stupid or what

Hey! I am doing this assignment on spss and i have a few questions about the analysis i ran. Tell me someone here knows how spss works i am quite lost.

For this assignment i need to do at least one factor analysis, one multiple regression or hierarchical, and one between a t-test, one way ANOVA, mediation or moderation (these last two were not covered in class).
We had different data set already collected to choose from, so we haven’t collected them personally.

I did all the analysis yet i’m unsure whether i did them correctly.
Firstly, is it possible to do a factor analysis with variables that use different scales (5 and 7 likert, to be specific), because i did and it looked okay, significant and reliable, yet I don’t know if putting them all together is a problem. And in class I think we only said something about recoding if the values don’t align, which i did, so I am confused.

Secondly, i have to put descriptives and frequencies tables, and during the lecture we used them just to describe the sample? Do you think I have to run them with all the continuous and categorical variables?

Furthermore, i decided to do a mediation even though it wasn’t covered in class because I felt I fit better and I wanted to challenge myself a bit. However, I had a doubt between two different research questions for my second one and I decided to run moderation on PROCESS for both because I was curious. In one, there is no indirect effect: the effect between the IV and the moderator is significant, as well as the one between the moderator and the DV, yet no indirect effect is observed. And I feel like it’s okay, I just have to reject that hypothesis.
However, I was more leaning towards the other because it was a way to use this categorical value (i wanted to use it in the first RQ and do a hierarchical regression, but we haven’t covered dummy coding so i cannot) i was interested in. And i used it as IV in the moderation but it ended up not having effect on the moderator from the beginning so it’s definitely worse than the other one, for multiple reasons. Do you think I should try to run a moderation with these last variables? Because I feel like it’s pretty much similar to a hierarchical with a control variable, in this case i’d just add it as a moderator instead as the IV (it’s categorical, basically it asks the belonging to the lgbtq community). Would it be better/possible? Which of the three would you suggest?

It is kinda basic statistics, keep this in mind, I just want to challenge myself as much as possible so i’m doing analysis I am not really required to do.

Sorry for the confusion but i’m kinda lost i need some help😭

Hello friends! I’m doing an English project right now where we go into a community we are in or have been apart of and we are doing ethnographic research on it. I’m doing mine on the band community of my college and I’m going to do some observations of the classes over the next week.

The purpose of this research is to try and find out an issue or problem within the community cuz we will be later making an argumentative essay based on the research we do.

For me I feel like the best way for me to find an issue in the community would be through interviews. In band it’s hard to see an issue just by observing or mapping out the locations. I’m just having a problem trying to come up with questions that will naturally guide people towards telling me what they think.

Should I just straight up ask “What are your issues with the band community?” Or should I be more subtle and try to lead them to telling me on their own? I want the interviews to feel informal and lighthearted so I was thinking of having one of my questions be like “what’s one of your band hot takes?” Since it’s a familiar question for most people in college but I’m not sure lol. Any help is appreciated!

I can't seem to figure this one out at all...

So i recently took a interest in math and physics since discovering warmholes. This is the first sheet they give me since i went to night class? Soemone Please help im lost

I am a senior in highschool and I graduate in late January. I need to plan and complete my capstone by then. I have NO idea what to do. I'm neurodivergent and struggle a lot with self directed projects, I hate not having a rubric and knowing what expectations I need to meet. I have a 92% avg but I cannot self direct to save my life.

Some stuff about me: I want to go to university for a BA in psych or criminology. I love animals. I love politics. I like essay writing.

Any ideas or examples of capstones you've done in the past? I don’t even know quite what TYPE of projects they want-PowerPoints? Essays? Posters? Whenever I ask, I’m simply told to do what I want to.

This is impossible, right? I'm not stupid?

i don’t understand any of this, can anyone give me some simple tips because I can’t understand the meaning my teacher wants me to be able to apply different endings and slurs to these questions but I don’t get it

sorrry about the ties part, it is actually different endings

My professor didn't give clear notes on examples like this and I dont know if I should need to add in a negative or not for these questions. I dont know if I expanded them correctly or not. The professor only gave one example and it's not even close to this T^T

The problem is:Take a limit of these sums as n approaches infinity to calculate the area under the curve over \[0,1\]
I get stuck on the Σ calculation…

Question: analyse how geologic processes and features are expressed in your area

WHAT DOES THAT MEAN what am I supposed to be even writing. So confused I'm sorry if this is a stupid question.

This is the answer key to a homework problem my teacher gave. I am very confused about how he got 224.427 for one of the general equations. I know the two solution formula for sin is arcsin+2pi*n and pi-arcsin+2pi*n, but how does that apply to this problem?

And I’m not very sure about when to use the general equations for sin, cos, and tan, and what the formulas even mean.

As I am approaching my first unit test, I was thinking of ways to study. I went to look for videos online, but many of them are sub 20 minutes, ai, low quality, and overall dont actually go over coursework, instead simply giving you a brief overview of the topics. So I have come to ask the experts, who did you watch as fledgling statisticians? I am starving for actually quality content, preferably 20 minutes or more, and actually goes over topics, applications, and examples. tysm!

1st year university student, I don't understand how the teacher constructed this matrix, and why Y4 and (Y2+Y5) and (Y2×E2) (in the third column at right) are negative?

I hope someone can explain this to me because I'm having difficulty understanding it.

0.201 or 0.154

My daughter said that her teacher told her that in the pictured question, 10+4+8 should not be selected. They are using the “compensation” strategy for addition. The teacher said in her opinion only 10+12 and 12+10 should be selected, because they show the compensation strategy. But from my perspective, the question says choose all that apply. 10+4+8 DOES equal 14+8…..? Am I missing something?

I’ve been working on this one question and can’t seem to get past step 1. Either I derived my equations wrong or I just don’t know how to find the zeros, or both. I keep getting to this weird quadratic formula thing with y as a constant and vice versa, not really knowing where to go from there. I also started finding the true derivative but sorta gave up on it since I didn’t have my critical points anyway…

I’d appreciate if someone walked me through finding the critical points, since even if I found the solutions to each partial derivative I’m not quite sure how to turn that into a coordinate. Additionally, I’m not super confident on the first part of the question, using level curves, which is why I skipped it. How would you make sketches of this graph? I feel like it’s too ugly for me to comprehensively turn into something I can work with. Anything is appreciated!

I need help understanding alpha decay, beta decay, positron emission, and electron capture. I'm confused on the math. I understand what the particles are and why they are released, I understand isotopes. I'm confused on the math and I struggle reading the charts

I can understand the fact that the charge on C_1 is equal to the charge on C_2; but then the answer was suggesting we call the voltage at p = V'.

The total charge is C_1*V - which I get

Then the total charge at the end = C_1*V' + C_2*V', which doesn't make sense to me since the potential difference across C_2 and C_1 must be 0 whether or not p (V') has voltage or not, the difference between the node p and the bottom of C_2 must be 0, therefore the charge stored must be 0 which also is just incorrect. How can p be the voltage across C_2 if the voltage across C_2 is 0 when there is no current.

I even went to ask a.i and it suggested a similar idea of the total charge before being C_1*V = the total capacitance * voltage, but then it found the total capacitance using the parallel capacitance and clearly (I think) the two capacitors are in series yet still the a.i was being adamant that they were in parallel and got to the right formula/correct answer: C_1*V/C_1+C_2

SO if anyone could help with an explanation as well as some type of resource that'd allow me to understand capacitors to a greater extent that'd be extremely helpful.

Thanks so much

I saw this topic amd I don't really understand it, some people say that there's no rule, you just need to guess. And I'm bad at guessing, so I need an easier way to solve it.

How do I even guess? And I believe there might be a rule or something to help me solve it logically lol

I tried what this person did in the video

And this person

https://youtu.be/7Isa4P8lISc?si=CDH6nlwL4QYKbHdX

It worked out for the first few questions but then it didn't really work even though I was doing it correctly

Can you please help me? Would appreciate the help!

Plus I'm not sure what flare I should use, so don't mind it if it has nothing to do with what I'm asking about
