Okay. I've forgotton how to do this one...
i) The average of 8 numbers is 15. When a 9th number is added, the average becomes 12. What is the 9th number.
And now for something a little harder..
ii)Write an expression for n
(1+ 1/2)(1+ 1/3)(1+ 1/4)...(1+ 1/n)
iii) A semicircle with...
solve for x:
i) log base 5 (1/x) = 1/2
ii )log base 2 64 = x +2
iii)log base a (x+5) - log base a (x-3) = 2
for ii)
i get 2^(x+2) = 64
x= 4
but that was from just trial and error..
is there another way ?
What exactly is year 11 ?
It doesn't count towards our HSC or anything..
I've heard it's just like a foundation year, hence prelim.
Do internal ranks matter in 11 ?
If I plan to go on with my current choices in mind for the HSC;
Ext. 2 English
Ext. 2 Maths
Physics
Legal Studies
But, I choose to do Ext. 1 Mathematics instead of Ext. 2, how is my UAI calculated then if the worst UAI contributor is Physics??
Ext. 2 English = 4units
Ext. 1 Maths = 3units...

WORRIED Qantas and Jetstar workers are waiting to hear exactly where the job axe will fall after the carrier said today it would dump 1500 staff and scrap plans to take on another 1200 workers.
The Australian Services Union...
Remember the 'promise' from Rudd about the computers?
Do you think us year 10ers will get one or whatever the policy encompasses allow us to at least use one ??
anyone have any info from teachers ??
one of my teachers said that we would be out of school by then..
Just wanted to know what makes a CV stand out apart from just
the normal stuff u put in like education background.. what i mean by
that is like i did the duke of edin. << so that kind..what else??
community service?
Okay. so for year 12 you need to do 10 units with at least 4 subjects ?
so if i do 12 units for the HSC and i do very badly but still pass in one of my subjects..say physics..then that doesnt get counted in my hsc? but i still get a certificate saying that i passed phsyics?
i was an audience to a debate the other day and the third speaker was quite funny.
