I was never taught something like this, sorry

so this is a paper for school, Just wanted some help critiquing it since I'm not a very good writer and I need to pass this class.PLEASE

By is it important for a culture to know its story? (History)

We live in a very fortunate time:the present, and with the privilege of being here now we can look at the past and see how we've grown, both as individuals, and as a culture. Every culture has a story and every story holds lessons. By looking back, we see our successes and our mistakes, the things that's shaped us and the things thats held us back, and we learn from all of them. History has a tendency to repeat itself, but its not always the events that repeat, its our reaction. By understanding and studying the past, we learn how we can react differently, how to make better choices and sometimes have an understanding of the outcome. When we don't preserve our history we risk erasing it, and when we forget where we come from, we lose a part of who we are. Knowing our story helps us understand the little but important things. Why we pronounce things the way we do, believe certain things, act certain ways. By beginning to understand where we come from, we begin to understand ourselves.

Help me with my assignment I don't understand question d and e

Is this how you solve it?

So I'm really bad at these composite and inverse questions, especially when they're in a fraction like this. I've been at this for around 40 minutes watching videos and attempting, but I just can't get the right answer.

Problem

I know show my attempts at solving, but this is what my professor solved in the lecture like literally he was suppose to explain, and instead he just solved without telling us the why, or what he was doing exactly he just written some numbers and units, and boom a correct answer can someone please help me out and explain?

I just started taking my Digital Computation class where they teach us MATLAB, and i do not understand the first assignment at all. can someone please help me out?

third slide is as far as i got, and i’m not even confident in what i have, nor do i even understand it.

problem

My professor, split the equation into two equations firstly [ X = Bt²], Second one is: [x = (C/B)t.

here's my question how is this mathematically sound? there is a + in between them not a multiplication or a division sign so we could split them into two parts.

and even if we agreed on splitting them how can we then get the dimension of C? I''m pretty sure my professor solved it correctly, but I'm missing something somehow.

I need an explanation on how to slove these problems, the solution with the steps would be helpful thank you.

Can anyone tell me where I went wrong?

Here is the problem and my sketch.

I only know how to do this on the school calculators i was never taught how to do without a calculator.

I am given a task to reframe a story as a research essay with a central question and claim.

Does this mean I have to create a question that circulates on the book itself, or it would be okay to delve into the topics mentioned in the book instead?

I definitely can’t remember this during an exam, trying to find a way to simplify it

A tad embarrassing, but I am having trouble defining “3 Steps to change a habit” under the “Health Information” (continued just above Stages of Adaptation) and “Stages of Adaptation and Adjustment” headings. Professor is specifically asking to define three stages of change within these sections, but I am quite confused. I’d truly appreciate any help!

I cannot for the life of me do this question. I think that applying constraints, both the blocks should have the same acceleration magnitude wise but i dont know where i go wrong. ( i might be complete wrong here )

wrt m, mgsinalpha - T = ma

wrt M, T = Ma

Again i am kind of an idiot and might be completely wrong here.

I decided to take AP chem for this school year and I was struggling on some of our assigned review work. Could someone explain Stoigonometry to me? Im confused on Avocardos 6.0000*1023 moles and how that relates with the elements
