I'll answer my own question... Serena invests 8000 at the begginning of each year into her supperannuation account which pays 10% pa compounded half-yearly, after 10 years, serena reduces her investment to 5000$, find the amount in the supper account after 20 years. Next question: given...

S = [a(rn - 1)]/(r - 1) r = 2, a=9, S=143 143 = [9(2n - 1)]/(2 - 1) 143 = 9(2n - 1) 143/9 = 2n - 1 152/9 = 2n ln(152/9) = nln2 n=4.08 you cant really have a partial term of a series, but that seems to be right

haha, pretty much the same, got 85 in the CSSA trial, and 86 overall, came first... but i'm aiming for a good band 6, just wish i new what raw mark was required for a 95 hsc mark, no matter though, it wont change how hard i try, still do my best

I did in the Wild, and i thought it was a really good question which really fit Wordsworth and malouf texts

haha, for those 2 things just do, sup in brackets and for the ones below, like 2 just do sub in brackets, and close the tags with the /, just click 'reply with quote' and you'll see em

haha, thats ok, were just taught to always put it in general form

already posted a question

Ok, i'll post a question Serena invests 8000 at the begginning of each year into her supperannuation account which pays 10% pa compounded half-yearly, after 10 years, serena reduces her investment to 5000$, find the amount in the supper account after 20 years.

thats some prove question!

Question 81 the area under the curve y = 1 / sqrt(x) for 1 <= x <= e2 is rotated about the x-axis , find the exact volume of the solid of revolution

haha, 'didnt get around to it' how could u not, i did the multiple choice, took a little break, did the short answer, put my head down for 15 min, then took my time doing the last part and finished 20 min early... But who knows how well i did, most ambiguous course

I misread the question and thought it meant the least important charactoristic of the material was first, therefore i chose C, i origonally had A but crossed it out- also, the graph never indicated whether the higher or lower the number on the y axis was best. "decreasing order of importance"...

85-90 most likely, probably an 86.5

ahh, cool- i always simplify first, cause its the only thing i ever think of doing, atleast you'll be good for the harder ones

Question 64 A glass has a shape obtained by rotating part of the parabola x = y^2 / 30 about the y-axis. The glass is 10 cm deep. Find the volume of liquid which the glass will hold. the population of a city is increasing according to the formula P = Aekt where p is the population, and...

Ahh. someone beat me to it, and i appear to be wrong, meh

Find the equation of the normal to the curve y=tan2x at x=4

Why must he beegees make such catchy songs? although, i must say- having tragedy running through my head during english was rather appropriate esp on module C... even though Grease cleary wasnt the word wordsworth was thinking in those poems

next question: find the area enclosed between y=sqrt(x) and y = x3
