That test was the worst test in which I have done so far out of all of my subjects. Thank god there's no more HSC mathematics for me for the rest of my life. Anyway, I did manage (I think) to get the mobile phone exponential question:
8(a) Correct
A = 984.6 mil
k = 0.4855....
Can someone check my answers? i'm kind of anxious... Did you get any of the following answers?! I know it doesn't matter anymore... but... XD
3(a)
(v) 200 units^2
3(b)
(iv) 200 days
4(b)
(i) 1/6
(ii) 5/6
4(c)
(v) (43pi-9-3root3) / 12
5(b) Incorrect
(iv) ln 32
6(b)
(ii) x=0,3
For x = 0... did you get a max/min... or was it a point of inflexion?!
7(a)
(i) S (0,4.25)
7(b) Correct
(ii) 4units^2
9(b)
(i) 39/52
(ii) 3/8
As you can see, I am crap at maths ='(
*cries*
6(b)
(ii) i think thats suppose to be a horizontal point of inflection
and for 4(c)
(v) (i got 19pi/6 +root3
cant remember the rest but i'm pretty sure ur proballitiy is wrong
Yep i got the same answer for 7a(i) too
