Yeah.

I'm estimating that I'll get about 10% for extension maths. :cold:

Probability of 3 boys and 5 girls sitting together: [8! / (3!.5!) . 135!]/143! = Ans Prob of 3 boys and 5 girls not sitting together: 1 - Ans I think that's wrong but whatever. My question: Differentiate y = 5x2 - 3 from first principles.

Extension maths was crazy, as expected.

Yes and no.

Study-wise: I'll be keeping it pretty light. Read english texts, that's about it.

:) Nicely done. If 85 was my worst mark I wouldn't disappointed at all.

I don't do biology but I suggest using tables to process your information.

My year 11 religion yearly was tough. Not looking forward to the HSC.

Well done. I didn't do it.

With the handwriting thing, try pressing down lighter and gliding across the paper (if you already haven't tried this).

Heart of Darkness is a novella written by Joseph Conrad in the year 1899. It is a dark tale about a man’s physical and metaphorical journey up the Congo River in Africa. Apocalypse Now is a film directed by Francis Ford Coppola, released in 1979, a war epic showing the journey of a man up the...

I studied the exact same topics as you. Here are my revision notes. By the way, as an important note, be sure to know how to relate the characteristics of each tradition for example, beliefs and sacred texts. The 20 mark essay question in the exam was something similar to: Examine three...

Mathematics was fairly good. Chemistry was the hardest exam I've ever done! Extension maths tomorrow. :uhoh:

I'd have to strongly disagree. I need teacher explanation to understand concepts.

If x=2^2 and y=3^4,express 4^6x27^8 in terns of x and y. 46.278 = (22)6.(33)8 = x6.324 = x6.34x6 = x6.(34)6 = x6.y6 = (xy)6

But it says solve by completing the square. I guess you could do it that way to check if you are right.

(a) I think you mean 8x4 - 64x. If so: 8x (x3 - 8) < --- Common factor of 8x taken out. = 8x (x-2) (x2 + 2x + 4) <--- Factorise cubic part using the difference of 2 cubes. (b) √48 - √27 + √3 = √(16x3) - √(9x3) + √3 = 4√3 - 3√3 + √3 = 2√3 (d) x2 - 8x - 9 = 0 x2 - 8x = 9 x2...

Read everything in the reading time and do the questions which come to you the quickest first. If you are stuck, MOVE ON!

True. I would do the following: Treat each couple as one which can be arranged 2! ways. Thus, you have 8 x 2! = 16 ways. That's wrong isn't it?
