how do u draw this: y=2x^3-9x^2+12 y=x^3-27x how would u get the x and y intercept?

hi guys, vectors r driving me nuts.. im havin lots of trouble with it.. Basically how do you differentiate between z1-z2 and z1+z2.,, how do the arrows indicate what it is? Also how does the paralelogram and polygon method, all the textbooks give the same example explainin it, but neva how to...

oh ok thanks. i heard from someone, you shouldnt discuss about syntax for a short story. is dat true?

to those who done and are doing OGS, wat scientists are easy to fit with most thesis's. my assessment is based on the quote " to get through the hardest journey we needto take only one step at a time but we must keep on stepping" <------ basically getting pass obstacles, breaking free from...

^My experiment was 2.3.5 in the Moving about topic. Plan, choose equipment or resources and perform first-hand investgations to gather data and use available evidence to show the relationship between force, mass and acceleration using suitable apparatus. Let me explain briefly: We had to...

and by that you mean?

^ i know i did everything right. Its just that one sets of the recordings i took down were non conclusive for each of the times i did the experiment. When you say wrong results = experiment done incorrectly, dats not necessarily true imo cos the quality of equipment may be a factor which made...

Hi, i have an assessment comin up and i have to write out the practical report inclass based on a experiment done earlier (related to f=ma). The things is, my results are nonconclusive, even after i repeat the experiment. So idk if it will affect my marks if i write the report based on...

electrical energy in the home: 2.3.3 2.3.5 3.3.1 3.3.3 5.3.2 Ye lol, my physics class is really bad. Thanks

Ive done the practicals already, some results are missing and inconsistent, just want to compare with others, i think itll be relatively the same.

Hi, does any1 have the results/observations for all the first-hand investigations of preliminary physics electrical energy in the home, that is the results for the pracs Please contact me, greatly appreciate it. Thanks

Ye i get what you mean the wide variety of uses of aluminium. But then ill have to discuss a whole lot on just aluminium. Names of actual mixtures would be appreciated. thanks

The assignment asks for the uses of the products after separation. Bauxite only gives aluminium. so idk if it would be a good mixture to do it on.

I want the best marks, so im prepared to go all the way. wat mixture would u extract aluminium from?

Hi im in yr11 and im having trouble with this assignment for chemistry. The assignment has to do with the industrial separation of a mixture. i need some suggestions on the type of mixture to do it on n some links to info on the process used to separate it. thanks
