I’m a year 11 student and very lost for ideas on my spoken exam any topic ideas would be greatly appreciated as everyone I have spoke to is doing it on social media and the mental effects of it, serial killers or football; as some one looking to do English language a level i preferably need a distinction.

Answer bank: zero, positive, negative.

On interval [0,10], the acceleration is ___

And so on:

[10,20] : _____

anyone know what i did wrong

Tried using xL = m+ tL x SE but didn’t know what to put for SE

I don’t even know where to start I’m so confused 🥲

anyone know where i went wrong

i’m confused on how u would do the voltages and current in v1 with nodel

How can I solve SOH CAH TOA. And find missing angles and special angles without a calculator. I cant find any videos online , if appreciate it if u send me a link to a video or explaine it . Thx I have a test in 2 days .

I know that we use SOH CAH TOA. But I’m struggling to figure out how to find sin(x) or cos(x) without a calculator how is that even possible . Please help

I did this a few months ago but I don't remember why or how I excluded the m from the equation F=m(v^2/R)

I was probably getting help by a tutor and skipped out on steps.

Can someone clarify?

Where does the - outside of the integral go in the last line of working, and how does the first step even work?

Can someone please help me with this cumulative distribution function? I'm trying to revise my class notes, and I'm struggling with how the professor determined the bounds of the integral. I understand why the lower bound is 1 since the lower bound on the interval is 1, but I'm confused about the upper bound. Any clarification would be greatly appreciated. Thank you

I'm doing question b) I solved the first part using the following 11+ (11+d)+ (11+2d)+(11+3d) = 56 44+ 6d = 56-44 6d = 12 D = 12/6 D = 2

Using the summary of the last four terms and calculating backwards 11 × (n - 1) × 2 11 × 2n -2 9n+ 2 (Using - 3 to -1) In thid formula (9n + 2) - 3 × 2

I got (2n+ 3) + (2n + 5) + (2n + 5) + (2n + 7) + (2n + 9) = 112

8n +24 = 112 N = 11

Did I get it right?

Don’t know what business math flair would be so I just chose this one. What is the formula I would use to get the answer?

I’ve tried multiple times and I cannot move on.

Ive worked forwards and backwards but allways end up with 19.423. im using the equations a=vt^2/r and vt=2πr/T as well as vt=Wr

Ok I'm sorry that everything is in italian. But i just have one question about this diagram and i hope i can give enough context so that someone can help.

In the documentation we are asked to implement the diagram for a website based on ticketing. Where a client opens a ticket asking for help with a specific problem. The ticket is then given to a technician to solve. I found this solution on the internet but I am confused about one of the choices. Basically, when a client opens a ticket, they specify which type of problem the ticket refers to. I feel like the way this has been implemented here is redundant, though! Because if you look at the "ticket" entity, it has the "problema" attribute ( which means problem, lol), BUT, it also has an association (riguarda, which means "regarding") with the entity "tipo" (which means type, and it refers to the type of problem). Isn't this redundant? Shouldn't I pick just one of these two things to specify the problem? Or am I wrong?

i am aware that the function is unspecified (0/0) and that the numerator is equal to 0, but no matter what i do the only thing i get is that a + c = 6 and i cant get any farther than that. any suggestions? thank you so much!

Please explain how to solve this step by step? So that I can do it myself with similar examples

1. (50) At Bob’s Burgers, each burger consists of exactly two buns x, one meat patty y, and one slice of cheese z. Let P denote the price of burgers and px,py,pz be the prices of each input and consider Bob’s profit maximization problem.

(a) (10) Write Bob’s production function q = f(x,y,z), show that it exhibits constant returns to scale, and find the marginal products to each factor.

(b) (10) Set up Bob’s cost minimization problem, write the Lagrangian L, and show why you cannot use the first order conditions to solve it.

(c) (10) Solve for Bob’s cost function C(q), and find the average cost AC(q) and marginal cost MC(q) functions.

(d) (10) Set up Bob’s profit maximization problem, find the first order condition.

(e) (10) Find the quantity of burgers that Bob supplies q(P), and find much profit he earns

Edit:

So I just found out if u integrate (x-2)^2 you do it as a single term? I used partial fractions (and wrongly, apparently because comparing coefficients of t, A =0) before this fact, and got what you see in purple and that was my answer.(wrong still)

What's this rule for squares of linear functions?

edit 2.00(2dp) lol, so I messed up at A while rearranging, A would have still been 0 bringing the equation back to its origins

After factoring the equation there weren’t any visible holes I would have been able to take out. So, therefore, I assumed there were none. I’d like to know how we’re supposed to know when to substitute 0 in for x to the function and the logic behind it
