we just had the half yearlies for maths. now the test was so surprisingly hard and since my teacher is an author didn't help either. i think i might've came 2nd with a approx mark of 22/45 what does this mean.

hello i was wondering how do we work out the school rankings if we know the results and what they are out of. for example i got 18/23 for first assessment and then 37/50 and the other person got 21/23 and 31/50. so who get first and who gets second. forgot to add they are both worth 20%.

forgot to add SOR where i am ranked not to good but yeah, i am planning to do extension 2 maths.

hello, i am in prelim but i just wanted to know where i satnd in terms of atar according to my ranks. eng adv-2/70 maths adv-4/70 maths ext-5/25 chem-2/40 bio-4/45 and my school rank is shit like 350 i think

oh ok so any number placed in the two found lines will achieve the required acute angle. i get it thx's so much

oh ok thanks so much but how do we work out the constants

i have reached the end of my past papers and there is one more question which i just cant seem to get. i kinda know how to do it but yeah. find the equation of any line which makes an acute angle of 15 degrees with 2x-2y+7=0.

how would u sketch y=tan(x-45) thx in advance

what textbook is this in, i think it was in my half yearlies. all u need to do is balance the equation. them multiply the mole of magnesium oxide depending on them mole ratio to get the moles of the other components. after this u use the mole formula to calculate the mass.

that is the way my teacher showed me but she showed us the pattern which we can use. but i posted the question on bos since i didn't want to remember the pattern.

that specific question is one that my teacher made, but it can be found in chapter 8 of the Cambridge textbook. excercise h

i have it written as quadratic functions but i think it comes under polynomials.

isn't this solving but?

i was trying to solve this question when i just couldn't find how. without solving the polynomial X^3-X^2-X+1=0 WITH ROOTS A,B AND C. find the value of A^3+B^3+C^3

what do u need just simplifying

i just got my results for my prac assessment and was really disappointed but i don't know if i deserved to get the marks i did. well there was three pracs part a i got 16/17 part b i got 12/15 and for part c my results were completely wrong so everything i did related to my results and hence...
