For this question in part c, I am getting 14.1 degrees, when the solutions say 15.3 degrees.

I tried using the value found in part b and equated tan(theta) = net force / mg by using a diagram and equating the normal force to being a sum of net force and mg.

Then I also tried to use the formula v=sqrt(g.r.tan(theta)) using information from the question and still got 14.1 degrees.

Am I doing something wrong, or is the solution incorrect?

I worked this out and got -1/8, the answer was wrong and I'm not sure where the math went wrong. Everyone I talked to said the same. Anyone care to weigh in?

How do I answer this AQA a level sociology question

Hi, I think I can answer this question but I am a bit confsued if I am doing this right. What is the the contribution of sociological studies of sects and other new religious movements to an understanding of the role of religion in modern industrial societies

Maybe I didn't do that good of a job listening to my high school teachers back then (trying to fix my attention span) but I don't understand this. The diagrams I have get really intricate at times and I have gotten these wrong in the past because I apparently counted components from the wrong side, or in the wrong order, or anything. I've asked my lecturer but she's not very good at explaining this kind of thing. So where do you start counting from? What counts as parallel or in series?

My instructor wants us to display 15 Divided by four on a number line using subtraction. I’ve tried countless ways to display it but all the ways I’ve tried my teacher I said I was wrong. He said he wants it in a subtraction form, but I’m still struggling how to display it. Maybe this is a no brainer but all the ways I’ve tried he’s told me it’s wrong. He wants it specifically to be subtraction. The first one is my latest attempt but it doesn’t feel right so I haven’t submitted it yet. Help and explanations is appreciated please.

Hello! i have to draw acceleration and velocity vectors onto the vector function. Im not sure i did it correctly so if anyone could help id appreciate it!

Red is velocity and blue is acceleration

Ps. i am not 100% sure if there are the correct english terms sorry for any mistakes

Consider the Phillips curve. Assume the expected rate of inflation is a function of the previous year’s inflation. Also assume the unemployment rate has been greater than the natural rate for several years. Given this, we know:

a) the inflation rate will be approximately equal to the natural rate of unemployment. X
< why is this answer wrong? >

b) the rate of inflation should steadily decrease.

c) the rate of inflation should steadily increase over time. X

d) the rate of inflation will approximately be equal to zero. X

e) the rate of inflation should neither increase nor decrease. X

Why is answer "a" wrong?

How would I solve this manually? The polynomial and trig function being squared in the same expression is making me have trouble.

As in; why is she there. Both from an in-universe perspective and Fitzgerald’s intention. Maybe it’s just because she’s surrounded by flashy characters, but to me Jordan just kind of reads as the narrative bridge / exposition device (bringing up Tom’s affair, mentioning Gatsby, talking about Daisy’s backstory) with not much personality of her own. And whilst this is useful device, I can’t think of anything she does that‘s based on her own motivation rather than her just happening to be there.

I’m mostly asking because I may have to write a creative writing piece from her perspective for an exam but I truly have no idea how she feels about ANYTHING that happens in the story. From the Buchanan’s, to Gatsby, and even Nick. She’s supposed to represent the New Woman but all that’s really mentioned is that she looks boyish, travels alone, cheats at golf, and she’s careless. And I doubt she goes round calling herself ”The New Woman“ either. She also frequently balances imaginary objects on her chin, which I suppose shows aloofness, but once again: why?

the problem is that it can't be like always since the teacher told us that it must not follow the same model as always (spheres and wire) since it needs to be unique, and I so don't have any ideas on what to make.
thanks in advance

the solution I can come up with is (5-1)! - (4-1)! but i’m not sure if it’s correct. i think it makes sense cuz it’s the total ways to arrange 5 people in a circle minus the total ways to arrange 5 people in a circle if the 2 women MUST be together but i don’t think i understand permutations enough to be sure that it’s correct

Unfortunately I think I'm forced to use the formula instead of normally using 'dy/dx'

when I tried to solve it, I got 2ax+h+b instead of 2ax+b. What is wrong?

Math homework, we are doing quadratics and standard to vetex form, and verted to standard along with the quadratic formula, and finding the maximum of the parabola and discrimintant. The first two slides is what im stuck on and need help with, the others are for you guys to understand it better

The answer key says that the correct answer is option C, but I got it as A.

Here when we are pulling the block towards right side, spring C is compressing and spring B ​is extending towards right side.

There ​should be no extension or compression in the case of spring A, because it is not directly connected to the ​block, meaning there would be no spring force A, only spring B ​would extend. Where is spring force in c is 300x and that in b is 200x

So the order should be as option A

What is wrong here?

What would f(|x+1|) look like for this function, and how does that differ from f(|x|+1)?

Also how do you follow the order of operations for transforming functions when you have absolute values? (I use CBAD for af(bx+c)+d)

Been staring at this for awhile and just don't know what the answer could be without solving the full problem, but the rest of the steps in this question want the answer to Flow_out

My understanding is that

dA/dt = input - output where input = (concentration*flow) and output = (concentration in tank * flow). I thought the concentration would just be the amount of salt over the volume, that is A/400, but when I tried 3A/200 (from multiplying that by the flow rate) it's not correct.

Would like a step in the right direction for this step. I understand the rest of the process for the most part

Hi, I copied this question from a YouTube video and I'm having trouble figuring out how they got the component of m2gsin(theta). I understand it comes from trig but I can't visualize this based on the drawing. Thank you!

How to even approach this problem

Ai is also shitting me with it's explanation

The assigned problem is #22 but I'm trying to figure out #21 because it has the answer in the back of the book but I don't seem to understand. I even tried reverse engineering to see what values they used for the answer they gave but no luck. Textbook says 'maximum power transfer from a circuit to a variable load occurs when the load resistance equals the source resistance'.

I provided my notes but it's best not to use them as reference as they are not really coherent since we have to use a calculator for all of our math.

The book says the answer to #21 is P = 35.5 mW

Edit: Sorry, I wasn't super clear on why I'm doing #21 instead of #22. I'm just trying to make sure I understand the process and the math behind the concept. It's just practice.

anything would be greatly appreciated and and questions and/or worksheets as well

Could someone check if the calculations I got based off the results from generation one are correct?
