Yeh the majority of people here seem 2 b going with 8,9, and 10.......add 7 to that and im with the majority!

 

[braindrainedAsh]

i got something in the realm of $400 for that. I thought 10 b (if I had more time I think I may have been able to get it, I was on the right track, but I hate those messy messy algebra questions) and the fish ones were the two that I had difficulty with.

question 7 was easy marks... apart form the the velocity bit

hi

For Question 9b, were we supposed to be able to find the areas of those sectors in terms of numbers or could we leave it in terms of r??? Because if they wanted numbers i completely stuffed that up! oops! Actually and i had that same problem for 9c - i left my answer in terms of u and v's. AHH!
And in answer to someones question before - i got that Barbera would have saved $550 for questino 10a iv about the loan repayments.
What about everyone else?

wat did ppl get for those blocks...?
how many rows...?
i think i got it wrong.. i wrote like 41 rows...

for the pizza - did you get an answer with 'r' in it?
and the veocity.. wtf, can someone tell me how you find the max velocity? i think i missed something in my study, otherwise i never learnt it

something around $1000-$2000

 

[Alex222]

i left mine in terms of 'r'...
how the fut do u get a value for 'r' anyway..?!

 

[SmokedSalmon]

I didn't really find any questions hard apart from that 9B) ii) the fish one was um queer.
And question 10 iii i didn't do.
Everything else was quite good actually

About the savings... I am not sure but I think it was close to what Alex got... damn this terrible memory

 

[Suney_J]

Q. 9 (C), and Q. 10,
apart from that the exam was easy

 

[Adam]

I think I got 72 rows, but I stuffed up the first time around.

errr u mean Angle BAO or what? for that i got Pi/3

because the value is Cos = root 3 /2 = 60 degrees = Pi/3

yeah, yes! i'm pretty sure i got that! did you have to convert sin120 to sin60 somewhere?

edit: and i got 73 rows for the bricks

well ok

for the two area of triangle question

i just used the 1/2abSinC rule and yea


for the region

i found the Area of the sector, then the area of the minor segment then i did Area of sector minus area of triangle and area of minor segment
