Can anybody help me with this q, probably pretty easy but I’m not very good at trig and catching up on what I’ve missed.

Can anybody help me with this Q: A cube is expanding so that it's side length is increasing at the constant rate of 0.12mm/s. Find the value of increase in it's volume when it's side is 150mm.

Been finding Physics kind of hard at the moment, especially dynamics. The math I'm fine with but I just don't understand the concepts and how to choose the right formula for a question. Once I have the formula I'm good because it's just maths at that point. Anybody else feel this way at the...

Only at a at the moment, I know x coordinate would be 0 but not sure how I'd find the y coordinate. I'm guessing the equation for the circle that B and A lie on is x^2+y^2=\lambda^2 so maybe y=\sqrt{\lambda^2-x^2} is the half that B lies on, I don't know where to go from there 🤷‍♂️

Anybody had to read Othello for English advanced in year 11 ? Is it really necessary to read all of it, or would it be more time effective to skim through it and summarize. We weren't actually told what we had to read it for but I'm assuming we will be assessed on it.

so since my school got flooded and we've had to merge with another one , our hsc trials (apparently) have been cancelled for next year. I believe their reasoning is that since we've missed out on a couple weeks worth of work we can't be assessed properly or something, which is ridiculous. I...

Anybody have a 3 unit Cambridge textbook for year 11 that they are willing to sell.

Currently using maths in focus for school assigned homework but I'm wondering if Cambridge would be beneficial to practice from as the questions are generally more difficult and similar to exam questions (from what I've heard that is).

For c since v = s/t then displacement= t*v right ? so since it stops at 2 seconds wouldn't displacement be, (2)(4)=8m in the solutions it says that the displacement is 29m, Could anyone help me see where i went wrong?

Not sure if this is exactly suitable for this forum but I'm wondering if anybody could be kind enough to proof read my English Advanced portfolio (for my assessment) and give me some constructive criticism. My school's been flooded so my teacher isn't available even if that wasn't the case I...

I'm confused about the concept of natural justice, is it just the same as procedural fairness ? Would this be a correct definition: the right to be heard by a court that is non-biased and a person's right to know what is alleged against them

so i thought this was pretty easy and got an answer of -28 for k \alpha+\beta = \frac{3}{1} -4+\beta = 3 \beta=7 so if beta is seven then using the sum of roots and solving we should get -28, but the book says -26 for some reason. can anybody explain please ?

so my teacher gave us some practice problems for relative velocity on a plane but I think his direction for displacement is wrong in the solution. shouldn't it be south-west because vector arrows are head to tail ?

I'm wondering if there are any specific study that one can do to help improve their responsive writing/analysis. I fee l that my creative writing is in a good place right now but when I right responsively my structure just seems kind of all over the place and messy. I usually use PEEL (all we...

Really struggling to solve this problem as the textbook only has a example solution which doesn't really explain anything. I understand the concept that like powers share the same coefficients but don't know how to go about applying it. I could only really get a=1, b=2 (Equal sign should be...

Looking for some past papers on Math Advanced topic 1 Algebraic tech and functions and also Extension 1 Polynomials. Would be greatly appreciated if anybody could share.

Not sure if this is the right place but I need some help with a question in my Ext 1 Math Homework. Our teacher gave us a whole exercise of homework but unfortunately didn't explain half of it. Question: The remainder is 89 when is divided by x-3, and the remainder is -3 when P(x) is divided...

How much should I be studying each week day and on weekends ? I'm trying to fit in 1 hour of exercise and 8 hours of sleep into each day. and I'm thinking of using the pomodoro study technique for all my tasks I need done. As for organisation I'm going to try get folders/binders for each...

Is there any specific maths that i should focus on improving/revising before next year, i'm doing advanced math and possibly Ext 1 (next year being year 11). I missed out on a fair bit of geometry but by looking at the syllabus i don't think stuff like congruence and similarity would really...

So I'm currently doing Advanced Maths, Advanced English, Physics, Business Studies, Legal Studies and SLR (Sports, lifestyle recreation - which doesn't go towards my atar just a nice PE break in between classes). I've been thinking of picking up extension 1 to help with physics and because math...
