I've got this revision sheet for Maths Homework and I still don't understand how to do changing the subject of a formula. Can anyone help?
kim, this gives and example of how to change the subject http://www.teacherschoice.com.au/Mat...bra/Alg_13.htmQuote:

I've got this rather bizzare sicence homework. I've looked but I can't find anything remotely relevant. I need to research poisons that contain potassium compounds. Does anyone have any idea of where I can look?
erm i dont know sorry, ill see if i can find out, if it helps bananas contain potassium lol!Quote:

That site explains a little about it.
Thanks Abi, that could be just what I'm looking for. It basically needs to be something cheap, and easily obtained, which would be found in a home or something. We have to write it in to our conclusion of a forensic science curriculum enrichment.
Cant believe its been ages since someone needed this thread!!!
Okay so I have to anlysis a speech, I chose this one from To Kill a mocking bird, I dont have to read the book, but i would like some background information on it please.
This is the speech I chose:
To begin with, this case should never have come to trial. The State has not produced one iota of medical evidence that the crime Tom Robinson is charged with ever took place. It has relied instead upon the testimony of two witnesses whose evidence has not only been called into serious question on cross examination, but has been flatly contradicted by the defendant. Now there is circumstantial evidence to indicate that Mayella Ewell was beaten savagely by someone who led, almost exclusively, with his left [hand]. And Tom Robinson now sits before you, having taken 'The Oath' with the only good hand he possesses -- his right. I have nothing but pity in my heart for the chief witness for the state. She is the victim of cruel poverty and ignorance, but my pity does not extend so far as to her putting a man's life at stake, which she has done in an effort to get rid of her own guilt. Now I say guilt, gentlemen, because it was guilt that motivated her. She has committed no crime, she has merely broken a rigid and time-honored code of our society. A code so severe that whoever breaks it is hounded from our midst as unfit to live with. She must destroy the evidence of her offense. But what was the evidence of her offense? Tom Robinson - a human being. She must put Tom Robinson away from her. (He gestures, pushing away with his hands.) Tom Robinson was to her, a daily reminder of what she did. Now what did she do? She tempted a Negro. She was white, and she tempted a Negro. She did something that in our society is unspeakable. She kissed a black man. Not an old uncle, but a strong, young Negro man. No code mattered to her before she broke it, but it came crashing down on her afterwards...Now gentlemen, in this country, our courts are the great levelers. In our courts, all men are created equal. I'm no idealist to believe firmly in the integrity of our courts and of our jury system. That's no ideal to me. That is a living, working reality. Now I am confident that you gentlemen will review - without passion - the evidence that you have heard, come to a decision, and restore this man to his family. In the name of God, do your duty. In the name of God, believe Tom Robinson."
Lawyer Atticus Finch's (Gregory Peck) closing argument to the jury In to Kill a Mocking Bird
__________________
OK, background. Its a while since I read this book and I didn't think it was worth all the hype. Anyway...
The basic time setting is in the South of America during the early twentieth century (1930s). Due to the Great Depression,poverty is a subject that affects many. Instead of using this as a binding theme, the people in the town use it as an element of separation. Prejudice of every sort runs rampant throughout the town, and even though things are simply "not fair", the time frame has to be remembered. Many stories have already occurred before the course of the novel begins but they're irrelevant if you're concentrating on the trial.
Atticus is another prominent character throughout the novel. As a white single parent, he faces the world, raising his two children with his maid, Calpurnia, (who experiences better conditions and responsibilities than other African Americans of her time, due to Atticus' beliefs). He has a reputation for being an open-minded, fair man, overflowing with integrity. It is also learned that he is self-educated, and tries to indoctrinate his children to love education and literature as much as he does. The relationship he holds with his children should also be noted. Even though he is incredibly busy Atticus always seems to find time for Scout and Jem, his children.
Tom Robinson, the accused, has a reputation within his own black community as an upright, honest, church-going family man. The Ewells, as a contrast to Robinson, aren't exactly noted for being model citizens. Bob Ewell, the father of Mayella, has a reputation for being the town drunk, allowing his children to miss out on valuable education.
The major event that has started to unravel, prior to the novel is the case between Tom Robinson and the Ewells. Robinson, who was a hired hand, is accused of raping, Mayella. The case falls into Atticus'lap, not because he believes that Robinson is innocent, but because it is his job to prove the latter so.
As Tom Robinson's trial approaches, Atticus worries about the safety of his client. This fear that proves to be justified. A group of townspeople, including Walter Cunningham, appear at the courthouse one night, with the intention of lynching Tom Robinson. The only person who stands in their waymis Atticus. At first, the mob intends to plow right through him, but with the unexpected arrival of Scout, they realize the error of their actions.
When Tom Robinson's trial finally begins, evidence begins to show that Robinson is obviously innocent. Heck Tate and Mr. Ewell take the stand in Tom Robinson's trial, giving further evidence to prove Robinson's innocence. Atticus points out that a left-handed man must have beaten Mayella Ewell. He goes on to show that while Mr. Ewell is left-handed, Tom Robinson's left arm is crippled due to a farming accident. When Mayella Ewell takes the stand, it becomes obvious that her story has many holes in it. However, she starts crying hysterically before Atticus may point many of them out.
When Tom Robinson takes the stand, the obviously true story comes out. It becomes evident that Mayella Ewell was a very lonely person who's only crime was to kiss a black man. Her father, Bob Ewell, beat and raped her for this crime. Mr. Ewell also forced her to say that Tom Robinson did it, so that he wouldn't get in trouble.
hey :) Stuck on the Myth of the given in my philosophy essay-
Is there anyway to put this so it makes sense? Or even an explanation of what the myth of the given is? :p thanks.
The myth of the given. one's particular beliefs about one's immediate sensory states presuppose possession of general beliefs or concepts - so the so-called basic beliefs are not basic. Our concepts cannot be derived or developed from 'raw', basic beliefs given in experience.
Hmm, tricky. I found this by Sellers on the Myth of the Given
One of the forms taken by the Myth of the Given is the idea that there is, indeed must be, a structure of particular matter of such fact that (a) each fact can not only be noninferentially known to be the case, but presupposes no other knowledge either of particular matters of fact, or of general truths; and (b) such that the noninferential knowledge of facts belonging to this structure constitutes the ultimate court of appeal for all factual claims, particular and general, about the world.
I've got an idea what that means but can't think of the right way to simplify it. What context is it in? Do you know what noninferentially means?
I've got it: There are two parts to Sellars' argument: first, he claims that knowledge is part of the "logical space of reasons;" and second, he provides an alternative account of "looks talk," or an alternative reading of such claims as "that looks red to me," claims that traditionally have been seen as infallible and as foundations for our perceptual knowledge.
So basically, we presume that because somebody has told us that something looks red or white then it must be red or white. The colour red is what everybody believes it to be, we don't conceive it to be blue.
Probably doesn't make sense.
No idea :p I've put
Sellers argues that your belief about your sensory state could be a false assumption of your general beliefs or concepts, but then this means that the so-called basic beliefs are not basic. Our concepts cannot be derived or developed from ‘raw’ basic beliefs given in experience.
but i guess I'll just ask the teacher tommorow. I wasn't in last lesson so he should give me until Monday I hope. Thanks anyways :D
HEELP :p Ok I think I'm being stupid here but I've got a total brain block on this :p
This ‘Measurement in Sport’ leaflet should include the units, devices and techniques used for making measurements of five different quantities in specific sports of your choice.
So any ideas on five different quantities? :p My teacher used the example of speed :searchme:
Thanks in advance :D
could weight be one, or distance.
Oooh it could be, thanks :D I'll do some googling :p
Solved the problem :p Luckily my mate was on msn..it was the way my teacher had written it he wasn't very clear :rolleyes:
Help! :p
I'm doing coursework on grapes. I need to find out an alternative method for finding the concentration of sugar in the grape juice.
I know there is an experiment involving testing the amount of carbon dioxide given off...by the grape juice. I think that's the one I should do..
But I can't seem to find any information on the internet..
Anyone done or researched this before?
Thanks in advance :)
Third paragraph under Must Weight http://www.thewinedoctor.com/author/sweetscience.shtmlQuote:
http://img516.imageshack.us/img516/4...efhydrojq5.jpg
The refractometer is precision laboratory equipment; or, more conveniently, it is a small hand-held device which can be used by the winemaker in the vineyard. The juice of a ripening grape is squeezed onto the device, which provides a sugar reading by the process of refraction. This process depends on how light changes direction when it passes between two media, in this case air and grape juice. The concentration of the solids in the juice affects the angle of change; measure the angle, and you have an indication of the concentration of the solids, which are mostly sugars.
A quite different method, however, is the hydrometer; this device is more likely (although certainly not exclusively) to be employed in the winery. The hydrometer is simply a hollow glass tube, bulbous and weighted at the bottom, so that it floats upright. As the concentration of solids in the grape juice affects its density, it will also affect how the hydrometer floats in the juice. The denser the juice, the higher the hydrometer floats; on the side of the stem is a scale, which allows the winemaker to make a reading. Just what the scale shows, however, depends on where he or she is working; there are many different scales for must weight.
This talks about making wine but apparently all wine makers need to know the concentration of sugars in the grapes before they start.
Thanks that was a big help :thumbsup: :D
I was wondering if anyone could help me with my maths revision.
I was looking through my quadratics revision notes and then I found that there was, what looked like a cubic equation; I’m guessing because one of the ‘n’s is to the power of 3.
I’m not sure how to solve it, would I factorise, because I’m assuming there’s 3 solutions since it’s cubic (I think).
Here’s the equation:
2n³ = 5n² + 3n
The problem I have is that I can’t factorise it into three binomials.
Well... at the risk of sounding wrong I'd do:
2n^3 = 5n^2 + 3n
Always add the powers.
2n^3 = 5n^3 + 3
Add the numbers (I think)
2n^3 = 8n^3
Not sure where to go from there. I'd suggest 2/8, which would be 0.25. I think you subtract powers so it would just be 0.25n.
Its a long time since I did GCSE (I did higher but only did one year of it) so its a bit rusty. Does the question ask to solve the formula?
What exam board and course are you doing?
wow its been a while since ive done this! yep youre right, cos its cubic there will be 3 values of n. start by making the equation equal 0 and then factorise it and in the bracket you should get a square equation (cant remember what thats called) and then work it out like normal. hope that makes sense, if you want any more help just ask :)
WJEC (CBAC in Welsh) and thanks for the help.Quote:

Thanks a LOT for that!Quote:

So, I think I've got it:
2n³ = 5n² + 3n
2n³ - 5n² - 3n = 0
n(2n² - 5n – 3) = 0
n(2n + 1) (n – 3) = 0
n = 0
2n + 1 = 0,
2n = -1
n = -½
n – 3 = 0
n = 3
n = {-½, 0, 3}
Could you check that please di marco? I would really appreciate it! :) This maths is really driving me round the bend.
Heya, okay so heres the thing I need to do my key skills for college and Im stuck on one of the parts, I have collected details on 12 houses for one town and then I have to work out the range, median mean and mode for the prices. But how to you work out the mode when all the house prices are different ? :confused:
There isn't always a mode.
Good, Thanks. Anyway I looked at the next section where I have to do grouped frequecny tables for the prices, so now it makes sense :lol: Silly me :p :o
Okies. So i'm kinda like really struggling with my RE coursework at the mo. ;[
We got it today and has to be in tomorrow. But i'm not giving it tomorrow as I have no time to do it. I've done most of it but I have to go dancing in like, a half hour!
Anyways, it's a section C question (evaluation question) about euthanasia.
'If a murdere wants euthanasia rather than life imprisonment, he should be helped to die.'
Do you agree?
Show more than one point of view and include chrisitan views.
We also have to pee. (PointEvidenceExplanation)
I've done the for and against but now stuck on personal opinion. Which I know may sound stupid as it's my opinion but I can't repeat anything that i've already put.
If anyone has any ideas of what I can put it would be soooo greatly appreciated. It doesn't matter whether it's for or against, we can lie thankfully!
So really just ideas - doesn't matter if it's not a full explained point :D
Thanks in advance guys x
Just so we can help you more.. what sort of things did you put for the for and against arguement (so that we don't repeat what you've written).
Or maybe... how many points have you written for each? Maybe you could take one out and use it as your own opinion..
