do u guys reckon 82/84 wld get a state ranking?

cause in rising LFPR: i wrote better economic conditions, hidden unemployed/ discouraged workers are re-encouraged to seek jobs effects: less hidden unemployed, rising equality of income/wealth, growth

hmm most of question 6 wasnt realli projectiles i mean (i) was distance formula (ii) was finding a turning point through differentiation (iii) this was the onli real projectile related question, and it was only 1 mark neway you just differentiate y = vtsin@ - 1/2gt^2. and let dy/dt > 0 and sub...

very happy with a performance! 84/84 at the moment i deduced all the 'show' questions only a few doubts:: for 1e i got 16,-16 3c(ii) i got 320 and q4(a )(ii) and (iii) not completely sure i got it rite

the centre was 5 + 3i, not (5,3) it asked for the complex representation also remember u when u draw the ellipse, it hasta 'touch' the x and y axis

err no its true u idiot its called the USYD Scholarships for Outstanding Achievement in the HSC for people who get 99.95 or 100.00

FFS 7 page thread on ONE question wTF? the answer is 0.3m for the dot point that says 'discuss the implications of length contraction etc. for space travel' length contraction is an advantage coz the SPACESHIP has to travel through LESS SPACE. if ur STATIONARY relative to an object...

It's B. once the centripetal force is removed, there is no force acting on the ball. Therefore the ball continues on its tangential velocity at the point of break in a straight line

anything between 85-90 is reallly really good given the way the HSC is strictly criteria marked. i hope for 90%

7.5 x 10^5 J is correct however, interesting to note that it takes less energy to move the object a further distance

i thought 1984 powerplay was very very kind i.e. the human experience thingo applied much better to 'power' than to 'truth' i talked about Winston's spiritual and ethical atrophy, how doublethink establishes a social facade to dictate human lifestyle, and newspeak/language which removes the...

i thought the hamletRAGAD was okish i talked about - how shakespeare's language represented the higher order - how stoppard focuses on the common man, to represent the loss of heroism&morality in XXth century. trivialising Hamlet who embodies moral order - how hamlet's procrastination...

Hoping for 4u Maths: 94 3u maths: 99 Physics: 94 Economics: 95 English Adv: 88-90 n hoping to meet UAI estimate of 99.50

but after you get d^2 x/dt^2 and d^2 y/dt^2 why dont you do sqrt ( [d^2 x /d t^2]^2 + [d^2 y + d t^2]) to find acceleration i.e. pythagoras

hi i have a question so if you have a particle moving in circular motion how do you find the accelerations of the particle say u have x = cos@ , y = sin@ you differentiate wrt t twice, but then how do u find acceleration? sometimes i see pythagoras used, but sumtyms i see horizontal...

1. let z = x + iy and u know that lzl = sqrt(x^2 + y2) so you get sqrt[ (x + 4)^2 + (y - 4)^2 ] = 2sqrt[ (x -4)^2 + (y - 1)^2] then u just square both sides and simplify 2. same thing lzl = sqrt ( x^2 + y^2) so 2sqrt(x^2 + y^2) = 2x + 4 then you square both sides and...

hi. last year in my school the top mark receieved in a subject was 98 - MX2 100 - MX1 (four people in fact) 97 - phys 96 - eng advanced 96 - economics i heard that no-one receieves 100 in the state for physics. while 3u maths gives out a lot of high marks (4 100's just from my...

hi could someone please help out here im quite confused about this.. the total air+road resistance of a car is proportional to v^2 (v is velocity). When the engine is disengaged the car moves down as inclined plane, angle arcsin (1/30), with a velocity 30ms. Find the force necessary to...

hey im stuck in this past paper question. would realli lyk help -------------------------10 i) Find the roots of z = 1 (i can do this part) -----------------------------10 explain why ( (z-1) / z) = 1 only has nine roots, show the roots of this equation are z = 1/2 (1 + i...

thankyou heapss i did most of what you did but i couldnt finish it before. nice UAI btw
