if you put your asnwer in the form 5million instead of 5,000,000 that should be fine :) (I know the answer isn't 5 mill but that's just an example)

Eh either way with a 90/120 that's still a high band 5 which is alright :) don't worry too much awkward_ninja

I think both are correct, abs(x)-2<=4-x^2 - Wolfram|Alpha seems to point towards it but I will add this answer too.

Hmm hopefully I just made the mistake now and not during the exam :p

You're right I'm an idiot what with saying n was 119 just did most of it in my head and I'm not really awake so I'm making stupid mistakes left and right :p thanks for correcting this.

Haha you're right it was stupid and I'm not claiming all my answers are right that's why I'm asking people to check :)

They're asking for the value of the integral not the area so in this case it would be negative.

Fixed 1a) I'm an idiot for doing that -.- haha 3aii) a=3000000 n=110 d=500000 Cost=\frac{110}{2}(2\times%203000000+119\times%20500000) =3602500000 hmm for 10 aii) you're probably right, I'm tempted to think it would be 90 though since they're asking for the maximum value which wouldn't be...

Well I got n>19.something Since it's greater than 19 and it's an integer I assumed it would be 20 however I might be wrong, not sure.

Haha oh dear now I feel embarassed, all fixed up thanks for telling me.

Happy to help :). Make sure to post if you find any mistakes.

I've made a thread with solutions, but I might have made one or two mistakes. http://community.boredofstudies.org/showthread.php?t=269025

Alrighty I'll just be rewriting the answers I got, if I got something wrong feel free to correct me since I'm just doing this off the top of my head with minimal working: Question 1 a) 3.728 b) n+5 c) x=2 d) %5Cfrac%7B5%7D%7B5x+2%7D e) -2%5Cleq%20x f) 2%5Csqrt%7B5%7D+2%5Csqrt%7B3%7D g) 16...

First of all thanks for taking the time to reply. Just wondering: will me not doing scif impact me at all?

Hello, I've had my eye on the combined degree of commerce and advanced mathematics for a while however after my hsc english test today I feel that I might not be able to get into it and thus will have to rely on my second option of doing a bachelor of commerce combined with a bachelor of science...

What do you guys think the cut off for a band 6 will be for esl this year?

Re: General Thoughts: ESL Had similar responses except for this, I said it connoted a positive attitude, despite the fact that one paragraph was negative he goes on to say "But... something has happened" and mentions that the examples of negativities are exceptions.

~85

Ah fair enough, good point thanks for the estimate :)

Hmm are you sure? He beat a friend of his in the same cohort in most internals yet got a lower estimate, what's pulling him down? edit: http://community.boredofstudies.org/showthread.php?t=266072&p=5492858#post5492858
