My thread of questions

[jaja]

2007 VCCA exam 1........Q11)... can i just leave than answer as (0.4 * 0. + (0.6 * 0.6)... or would i need to multiply and then add the decimals??? if i
just leave it like that would i still get the full 2 marks???

Q8b)... how do you get 7/4.. .didn't understand VCCA's answer

[TonyHem]

Multiply it out

For this question, if I just wrote: cos^-1(y), y cannot take values greater than 1, would this suffice?

[khalil]

Also, do they mean a<0 in this question or am I just drunk?

when therefore the asympotote

yes a<0

[khalil]

quick question: if question says dilate along y axis, does that mean the x values change or the y values?

quick question: if question says dilate from y axis, does that mean the x values change or the y values?

X values

[khalil]

srry, I meant 'along'

[kurrymuncher]

then the Y values will change

[khalil]

Then is there a mistake in the insight exam 1 2006 Q2)c)...please check

lols maybe Im just wrong, I had too many trial exams in the past three days  :buck2:

wait for TT

Along y axis just means dilate FROM the x axis, so the y values will change. kurrymuncher is right pr0 pr0

[khalil]

Can

Assuming [A reason for the assumption is 1. A lack of information 2. Working backwards from answer]

Dilation factor of along y axis means from x axis.
