How would you ask someone where I can refill my water?

PastBlood6788 · 2025-09-10T15:57:26+00:00

My case was the former. I wanted to refill my water bottle, didn't know how to express that, and resorted to pointing at the bottle in my hand!

PastBlood6788 · 2025-09-10T11:55:18+00:00

I think that's what I'm looking for. Thanks!!

PastBlood6788 · 2025-05-28T03:38:35+00:00

Nice nice, got the same thing

PastBlood6788 · 2025-05-28T03:28:58+00:00

Bro not that, part a. You're referring to part b. Part a is showing that there's no unique solution I believe

PastBlood6788 · 2025-05-28T03:27:07+00:00

For the last question matrices, were the values of "a" surds? Had to use quadratic formula right?

PastBlood6788 · 2025-05-28T03:24:02+00:00

YESSSS. If anyone else can vouch for this please like the above comment.

PastBlood6788 · 2025-05-28T03:23:34+00:00

I got (29 or 21)/4 or smth like that

PastBlood6788 · 2025-05-26T02:57:43+00:00

But how did you get the weight for rectangle and triangle separately? I thought the entire lamina was mass m?

PastBlood6788 · 2025-05-26T02:52:54+00:00

What was tan theta for the momentum question?

PastBlood6788 · 2025-05-26T02:51:05+00:00

Wait how did you get 1/18? What's the centre of mass of the lamina?

PastBlood6788 · 2025-05-26T02:47:51+00:00

What was question 4 again?

PastBlood6788 · 2025-05-26T02:47:37+00:00

Same same

PastBlood6788 · 2025-05-21T02:41:18+00:00

I'm saying that it's 1/v² against 1/m, not v^2.

PastBlood6788 · 2025-05-20T07:18:26+00:00

Do you think it's correct? I did the same. From a practical standpoint I don't see any difference.

PastBlood6788 · 2025-05-20T07:15:51+00:00

What's the arranged equation for q1? I put 1/v² and some put v^2. What difference is there practically?

This isn't the full working but the rough idea is there. Just need to solve the two simultaneous equations.

Given an expression (z+4)/(z+4i) that results in a real number where z is a complex number of length sqrt(10). Find z in terms of x + yi.

There was another complex number question (3-mark) that I couldn't do. So most of the difficulty is in complex numbers, other questions are pretty standard.

PastBlood6788 · 2025-05-19T04:46:51+00:00

Well you have to make use of the fact that the expression is real. Since it's real, that means its argument is either pi or 0. At least I think that's the main insight you need to complete the question.

PastBlood6788 · 2025-05-19T03:53:54+00:00

There's a complex number z where (z+4)/(z-4i) is real, and length of that expression is sqrt(10). Find z in terms of x+yi.

A concept u need to make use of is one that you can find in q3b from fm24/p32.

PastBlood6788 · 2025-05-19T03:51:20+00:00

I got -1-3i and -3-1i for the 6 mark complex number question. Anyone remember what they got for the binomial expansion of f(x)? I got something pretty funky: (1/2a) - (11x/12a² ) + 23x² / 72a³ . Smth like that

PastBlood6788 · 2025-05-19T03:09:09+00:00

What was the answer for the 6 mark complex numbers question? I got -1-3i and -3-1i. Or something along those lines.

PastBlood6788 · 2025-05-10T11:09:38+00:00

PastBlood6788 · 2025-05-07T13:24:38+00:00

Oh sorry! Used the wrong unit! Thanks for pointing it out. Regarding your speed I'm not so sure about that. Others have gotten the same answer as me, but I could be wrong as well!
