norain214:36pm: Quadratic Equation in Geometry

I'm ready to go insane. I have the answers, but nowhere in the book does it tell me how to solve these problems. I've no idea where to begin, and when I try to guess, I get sloppy, wrong answers. Help?

whatever_freak3:52pm: I need help with my English work, well it's not really work we've just all been given an extract of Duchess Of Malfi to 'translate' and I'm having trouble with my section.

I need almost a word-for-word 'translation' of these few desctiptions of the madmen from Act IV Scene II:

"an English tailor, craz'd i'th' brain
With the study of new fashion;

"a gentleman usher,
Quite beside himself with care to keep in mind
The number of his lady's salutations,
Or "How do you," she employ'd him in each morning;

"And let one broker that's mad loose to these,
You'd think the devil were among them.

And then the Duchess says:
"Let them loose when you please,
For I am chain'd to endure all your tyranny.

I'm sorry for basically asking you to do my (fairly easy) work, it's just that we're being made to tell it to the class and that makes me nervous enough so I'd just really like to know that what I'm saying is right!

Thank you so much for any help!

I really need help with my homework assignment *^*
You see, In my digital media class, we are working for a client. We have to create a video or a PSA [Public Service Announcement] and present it to a audience. I'm having a hard time coming up with something for a audience of 20 to 40 year old adults. I'm trying to make an interesting story or a PSA but I really need you're help!! It's quite difficult for me T^T

My topic is "Rise Above Plastics". its an organization that fights to get rid of plastic pollution in the ocean. (you know such as bottles,plastic bags etc) these are bad because animals eat these plastics believing that it is food causing the death of millions of animals.

I really want to convince them that we need to do something about this problem. I've been trying to come up with something for a week, but nothing works...I'm so lost :[...
Can you guys PLEASE HELP?

Hey everyone!
This is my first post here, so I hope I do everything right.

I'm desperate on this one!

Does anyone know anything about the nearest insertion algorithm?   Not how to do it, but who developed it?  When it was developed? Anything? I have to write a report on its history and I'm googled out.  Any links would be greatly appreciated!

xgosniffglue10:13pm: French
Hey guys, this is my first French composition for my 130 class, due on Friday. If you could simply proofread it for grammatical and spelling errors, I would really appreciate it. Also, I would like to use le subjonctif in the places where it is possible, so if you could point out some sentences where I could do that (I've always had trouble figuring out where it can and cannot be used), that would be great too.

areopagit_com6:52pm: MindReader and learning

The specialists of the International center for education "Areopagit" (www.areopagit.com) develop the "convincing" to learn program. This program is designed on the base of the research of Dr. Igor Smirnov “Semantic Stimuli Response Measurements Technology”, or SSRM Tek, a software-based mind reader that supposedly tests a subject's involuntary response to subliminal messages.

The program inspires to recipient an idea about need to learn, think and develop their own abilities. If to unite this program with a network self spreading module (like a virus) then during several months it would install on hundreds of thousands of personal computers around the world. Besides, program can define the language of the user and use suitable - an English, French, Chinese, Spanish, German, Russian or Arabic.

okami_lup_wolf8:20pm: Factors/Multiples
Hi. I'm a new member, pleased to meet you.

Alright. I have worksheets on getting the GCF/LCM of a set of three numbers.

Does anybody know of someplace that has a printable guide to these, like a listing of all factors or multiples up to, say, 100?

I know this is kind of simple math, but still. It would be so much less time-consuming to find a guide to it.

chiibiusa7:18pm: two quick questions about the eye:
hello everyone, i've tried looking everywhere for answers to these questions and haven't found anything :(

1. How many green cones are in typical eye?
It said in my notes that there are 7 million cones in a regular eye, and somewhere online I found that green cones take up about 32%, so mathematically there should be 2,240,000 in the typical eye but I couldn't find a direct source that said green cones are x amount.

2. A red cone sensitivity at shorter than usual wavelengths is called ___________________________?
Protanomaly? I'm not 100% sure on this - there was nothing in my notes about it and this sounds like the answer given from the wikipedia article on color blindness.

Thank you for any and all help!

againstsex9:08pm: algebra
Hello, I have an algebra question involving three equations with three variables (well six actually, but they are two different sets). I have solved them, but I don't think the answers are right and I was pretty much winging it, so an idea of how to properly solve one would help. The two sets of equations are behind the cut.

I was wondering if I could get any ideas on the Totalitarianism Russia (1917) when Vladimir Lenin came into power?? Where should I go with this? Economically it helped the prolarairats and the working class? I'm at my wits end for this...any help please??
Current Mood: hopeful
emotionsaside1:55pm: I'm working on a history project, but I have no ideas for it.
The subject is imperialism. I have to come up with two similes describing an imperial power and one of its territories. One simile is from the perspective of the imperial power and the other from the territory. The similes need to be connected somehow.
Ex: From the perspective of a student, school is like a factory.
I also have to supply reasons why the simile is appropriate and include historical facts.

Any ideas would be greatly appreciated!

calcifer1311:39pm: English question

Please help.  I am non-native English speaker. .  So I've been struggling in understanding the following sentence.

>The prominence and acceptance of biometric technologies such as fingerprinting, facial recognition, hand geometry, and iris recognition may leave little demand for other modalities.

It is about Biometrics recognition - vein pattern recognition.

err....what I don't understand is this modalities.  does it means. -->the classification of logical proposition according to their asserting or denying the possibilities??
or something like MRI, CT the medical equipment? 

So in short it means    this excellent technology is about to launch since all the procedures are almost done.
this excellent technology does not need medical equipment to proceed?
or neither of the above...

Sorry, somebody please explain to me.
