Solutions please :) Thankssss!

Hmm which one do I use bro? I'm trying to find the cell potential of the elements: Aluminium and bromine. Hence I need the oxidation reaction of bromine - but it's got 2 voltages.

And what is the oxidation reaction of bromine?

The cell potential thing.. I know it's zero but why?? And where di they get zero from?

Weighting = 10% I really hope that's the case. Thanks for the reassurance :)

I had to hand in an equipment list for an assignment which involves an experiment we gotta undertake in class. I wrote down all the wrong equipment (ie for a different prac) am I screwed? will I lose marks?? :( :( :(:spzz::spzz::spzz:

Ohh, thanks hit, Heroic pandas, QZP! :) Ahaha really? Well that justifies my freak out lol!

Heroic pandas! How do I draw it..

nah, I'm pretty sure it aint. Cause for this example, 3x^4 − 4x^3 + 2, The answer is zero...wtff

Find the turning points of the polynomial 4x^3 − x^4 − 1 and hence state how many zeroes they have. How do you find how many zeroes they have? Answer: 2 zeroes

A polynomial of degree 3 has a double zero at 2. When x = 1 it takes the value 6 and when x = 3 it takes the value 8. Find the polynomial.

the polynomial p(x) is divided by (x-1)(x+2). find the remainder, given p(1) = 2 and p(-2) = 5 [Hint: remainder may have degree 1]

Write down the general form of a monic quadratic for which one of the zeroes is x=1. Then find the equation of such a quadratic in which the curve passes through (3,9). Thanks

p(x) is an odd polynomial of degree 3. It has x+4 as a factor, and when it is divided by x-3, the remainder is 21. Find p(x).

LOOOOOOOOOOOOOL whaaatta legendd

a) Prove that every odd polynomial function is zero at x=0 b) Prove that every odd polynomial p(x) is divisible by x. c) Find the polynomial p(X) that is known to be monic of degree 3 and an odd function and has one zero at x=2.

How do you write worked solution to this? For what values of m are the roots of x^2 +2x+3 = m(2x+1) real and positive? Answer: 2<=m<3 EDIT: Sorry the I didn't write the answer properly. How do you do it?

1) How many are there? 2) What are they usually based on? 3) Is there any way of preparing these holidays (next term I'm starting year 12) I suck at creative lol.

Heeeeeey guyyss Can you please help me out with questions 6, 7, 8d, 9 and 10c in this pdf? http://www.boredofstudies.org/courses/science/chemistry/1204620000_2001_Chemistry_Assessment_Task.pdf Thank you for your help!

Is it important to remember year 11 chemistry practicals for the HSC? We didn't complete some of the pracs and I'm wondering whether this will affect me in any way. Thanksss ;)
