A belated happy birthday wish!

Don't move schools. Having 3 unit maths out of the way in yr 11 gives you time to focus on other subjects in yr 12. This will put you at a massive advantage and will in the long run, maximize your ATAR.

hey guys, I've got another question. sorry to be a pain. A drinking glass has the shape of a truncated cone. If the internal radii of the base and the top are 3cm and 4 cm respectively and the depth is 10cm, find by integration, its capacity. If the glass is filled with water to a depth of 5cm...

Thanks guys LOL, a majority of my school grade knows this stuff. I guess after the SC everyone tends to work a little ahead.

Thanks man

Find the volume of the solid formed when the region bounded by the parabola, y=9-x^2 and the co-ordinate axes is rotated a) about the X-axis b) about the Y-axis Thank in advance, working out would be appreciated.

Memento by Christopher Nolan is pretty good. It's like inception, in terms of the psychological thriller theme.

no worries

The midpoint of a circle's diameter is its centre. so 4+x/2=1 -3+y/2=1 hence x=-2, y=5 so co-ordinates of A(-2,5)

ABCD is a kite. The area of a kite is given by 1/2xy (x and y being diagonals) so from multiply the answer from part i by two to gain the area of the entire kite. so 168= 1/2x 25 x BD BD= 13.44

Adding the ratios together gives you 12 144/12= 12 hence 12 sheep equal one portion so Bill's amount is given by 2x 12= 24

Tsunamis are formed when there is an earthquake or volcanic activity underwater. Need to revise for cyclones and volcanoes. lol

Your can sub economics with engineering studies to make another possible curry combination.

LOL, it's from the 2008 SC, that shows how smart the SC question writers are.

Two cars are travelling towards each other at 60km/h and 80km/h. How far apart are they 15 minutes before they pass each other?

For extension English it really depends if you are a frequent reader, and if you inherently enjoy it. All the teachers at my school said the subject requires a lot of your own time. The content you will do in extension English will not reflect what you will be doing in advanced. So, if you are...

Does option scaling apply to physics and chemistry as well?

oh okay no worries. thanks

if I use the formula for the -4 gradient I am getting 75 degrees and 56 minutes. The answers ,however says 104 degrees and 2 minutes. Can you explain why?

The line y=x+4 cuts the parabola with equation y=x^2-2x at two points A and B. Find the magnitude of the angles that the tangents to the curve at A and B make with the X-axis. Thank you in advance for any help. (working out would be appreciated)
