    oh quiz fark!

    It's worth alot less than 15% if I remember right. But that doesn't mean you don't have to worry about it. :P

    dividing lines according to ratio question - kinda simple but i'm not getting it.

    1) Draw yourself a diagram and label all 3 points. 2) Select two sides of the triangle and find the midpoint of each. 3) Note that a median is a line joining the vertex of a triangle with the side directly opposite the vertex. Now find the equation of the line that passes through the midpoint...

    Graphs - how much detail?

    Usually the question will specify how much detail. If not, refer to the number of marks allocated. If it's like 1 mark, then the basic features should be sufficient (e.g asymptotes, intercepts). More marks usually indicates more details needed (e.g turning points and points of inflexion). In...

    derivative question

    The information given is enough to derive 4 formulae which you solve simultaneouly for a, b, c and d. 1) Since curve passes through (0,5), substitute x=0 and y=5 to find an equation involving a, b, c and d. 2) y'=3ax2+2bx+c Now there is a turning at (0,5), so when x=0, y'=0. Substitute these...

    simple interest?

    In the topic of series and sequences, simple interest isn't really related, but is covered in the financial mathematics section of the course. It's examinable.

    Topic1: Globalisation

    This is arguable, and for that fact, is best if you provide both sides of the argument in your answer. TNCs may misuse the dominance such as through higher prices in their exports. However, they may be more efficient than other smaller businesses or firms and produce better quality...

    The UNSW bus queue at Eddy Ave

    You would expect a considerably shorter line (or no line at all) if you're catching the buses (which don't stop at central) from the second bus stop opposite UNSW. Otherwise... line up and be patient.

    Heroes (Aus Airings)

    I like how a few of the characters are already interlinked. SPOILERS below. The fire with the invincible girl walking through the fire and the artist painting it, then others watching the news about it on tv. And then that taxi driver and the two brothers that can float. Also the jap guy...

    you think about friction and the laws of momentum while pushing a shopping trolley.

    Couple Binomial Probability Questions

    I'll try the first one: p(wet)=18/30 p(dry)=12/30 a) p(2 wet then 2 fine) = (18/30)2.(12/30)2 b) p(3 or more rainy days) = p(3 wet) + p(4 wet) + p(5 wet) =(18/30)3.(12/30)2.5C3 + (18/30)4.(12/30).4C1 + (18/30)5
