This question is from Ex. 3.2 of Terry Lee's textbook. Factorise x^5+5x^4+6x^3-2x^2-7x-3 as real factors, given that it has a repeated zero. The suggested solution is: f(x)=x^5+5x^4+6x^3-2x^2-7x-3 f'(x)=5x^4+20%20x^3+18%20x^2-4%20x-7 f''(x)%20=%2020%20x^3+60%20x^2+36%20x-4...

It seems that it was fair as long as everyone was in the same situation. However, for example, student A might spend most of the time allocated doing questions of the wrong topic with which they were stuck, whilst student B only concentrated on questions of the required topic during the exam...

I think the Board will notify you on the Friday or over the weekend before the ceremony if you top a subject in the state.

Thanksss

Yes, I attend 4U in Hurstville. You also go to Harry's, don't you?

I'm good :) I just can't be bothered doing Harry's HW as I already have had loads of assessments and assignments from school.

I think we should use permutations here as the order does matter. So, the answer should be 6P2*6! ways = 21600

Your first answer is correct. However, the second one should be 21600 as shown at the back of the book. BTW thanks for your help :)

A minibus has 6 forward facing and 2 backward facing seats. If 8 people use the bus, in how many ways can they be seated (a) if 1 person must sit in a forward facing seat (b) if 2 people must sit in a forward facing seat? Thanks in advance :)

My mate actually did. He did General in Year 8 and then Math Ext 1 & 2 in Year 11. That said, it was Math Ext 1 & 2 that counted towards his ATAR apparently.

You should give spring rolls or Dim Sims as prizes to those who have the same combination as you.

Hey how is it going?

I also think my subject combo as shown in my signiture is quite unique. I am probably the only one in NSW who has this combination :)

Are all these marks out of 200? If so, your ATAR will be 30.

I did 750 words for my speech on Othello in Year 11.

Yes and no. I'm fob yet my HSC subjects are both yerrow and white.

Does it mean I should feel EXTREMELY ashamed of mine haha? Your school is actually far better than mine considering their respective rankings. BTW did you skim through every single posts or threads here in an attempt to look for who I was? lol

Yeah I do know the reason. Nice to meet you BTW! However, it would actually have been awkward if I pointed out you two lying about your names and schools :P So you should feel grateful for me not doing so haha!

I don't think that's random. You were asking for a reason mate :)
