Sure thing

could you plz explain Q9 2006 exam 1 Geo + Trig

only qn i got wrong in that exam  :x

i initialy thought it would be an isoceles but realised it cant be...

edit: also do you have the answers for the 2006 sample? or can u post what u got so i can compare (aparently they dont make answers for VCAA sample exams)

Um I don't do geo and trig sorry... i suck at bearings lol

As for the sample I havent done it just yet... I'll do it asap

They show you how to work out Qn 9

thanks... yeh im just about to start the 06 sample too, internet is too distracting lol

Tell me about it lol... i'll probably work on exams later today, i think better at night lol

[maxleng]

k so i did them..

Core:
A, B, B, B, C

Geo:
D, C, C,

Bus Math:
D, C, B,

Networks:
B, A

draw the diagram
its basicly like this

| ---------------M
|
|
|
O
|
|
|            
| ----------P
 
therefore the bearing of P from M is between 180 to 270

Okay Odette, here is your chance to help me out.

I just did the VCAA 2006 paper (part 1) and got 36/40.

The questions I got wrong were...

Core - Q10
Number Patterns - Q6, Q9
Matrices - Q7

No questions incorrect for graphs, which is comforting.

So... if you could guide me through those questions it would much appreciated, thanks!

A, B, B, B, C

Geo:
D, C, C,

Bus Math:
D, C, B,

Networks:
B, A

I did the core,geo, and bus man, i dont do networks ...

I got:
Core-
A,B,B,B,C
Geo-
A,C,C
Bus-
D,C,B

joechan521 i think i got it,

becuase P is 152T its 62 past 90 where as M is 52 behind 90 (imagine 90 as being perpendicular with O) so that means P is closer to the vertical and M more 'further out' given there the same length..

i just had problem on which would be futher out the M or the P, geting the bearings from that is easy, thanks!

edit: oddete

i dont see how u got C for q4,core... did u do .5675 x (67.98/8.67) ??

and geo q1, x = 34.6/tan(23) ??

CORE 10
its asking for april
so therefore you get 3 data from march april and may which are 35,99,75
find the average [35+99+75]/3 about 70 therefore C

MATRIX 7
many ways to do it

graph the 2 equations
if they intersect = a unique solution
2 parallel lines = no unique solution

or other way to do it.
rearange the 2 equations in y=mx+c form
if same gradient = no unique solution

Thanks joechan... added them in my 'notes' part of the textbook. Now for those number pattern ones Odette =]

Ok well I'm not too sure about the matrices question, but I can help you with the others...

CORE-
10. C
35+95+75=205
205/3=68.333
which is closest to 70

Number Patterns-
6. E
t15=12 x 1.03 ^14
t15=18.2

9.E
S∞ = a/1-r , a=0.4, r= 0.95
S∞ = 0.4/1-0.95
     = 8
=> 73.4 + 8
    = 81.4

Sorry about that...
Hope the others make sense, if they don't let me know
