    atar estimate for me please? hsc 2012.

    yeah, if your looking at that.. then i'd say go off what previous dux's usually attain. for me, i went to a school ranked ~280ish, but our dux's usually consistently received 97,98 atars. I came top 3 in all my subs, and ended up with 98.75. So i'd say best estimation would be of previous...

    Atar Estimate for me and a friend

    you: 95 (lower ranks but better comb. of subs) friend: 95 ish (high ranks - dependent on performance in externals) this is assuming that your high ranks in standard english is representative of how you will go in the actual HSC, e.g. relatively high band 5's in st eng.

    pH of resulting solution

    WRITE THE BALANCED EQUATION. Ba(OH)2(aq) + 2HCl(aq) -> BaCl2(aq) + H2O(l) n of HCl initial = C x V = 0.030 x 0.015 = 0.00045 moles n of Ba(OH)2 = 0.010 x 0.020 = 0.0002 moles from eqn) -> n Ba(OH)2 : n HCl = 1 : 2 therefore, n of HCl reacted = 2 x n Ba(OH)2 = 2 x 0.0002 = 0.0004 moles n...

    Maths Help.

    I understand that if you firstly just do f(2) you get y=4+In2, so therefore on the graph f(x) there's a point (2, 4+In2). And then therefore on the inverse graph f-1(x) there's a point (4+In2, 2). Now where do you go after that?

    what is y_1?
  18. D

    Maths Help.

    what is the inverse? so firstly you let f(x) = y, therefore y = 2x + Inx then to find inverse, you swap x and y: x = 2y + Iny how do you solve that equation for y?
