i got a math question that i couldnt get":

the textbook asks me to write the following as a single fraction:

... 1 + 1
./`5 ./`3 =


the answer is ./`3 + ./`5
............................../`15


i need to know how to get the answer.

Use the LCD. Multiply (1/5)^.5 by (1/3)^.5 and (1/3)^.5 by (1/5)^.5 then add. ^.5 means square root

thanks so much
cant believe i didnt see tat

i tried rationalizin the questions then went "huh?" with the answer i got

Thank You Very Much

Hey everyone, I'm having trouble with my math work and the equation of a straight line. Just so you know I'm only a 12 year old so please don't tell me any stuff I won't understand.

My teacher told us stuff and I didn't understand a bit of it and she wouldn't explain it to me again.

I have a horizontal line along these axis, running on x axis from -4 to -2.5 (3 centimeter boxes across) it is at 2 on the y axis. What I don't get is what to figure out. My teacher said something about triangles but I don't understand. Also, we have to use the equation y=mx+b as a basis.

I need help quickly please.

Hey everyone, I'm having trouble with my math work and the equation of a straight line. Just so you know I'm only a 12 year old so please don't tell me any stuff I won't understand.

My teacher told us stuff and I didn't understand a bit of it and she wouldn't explain it to me again.

I have a horizontal line along these axis, running on x axis from -4 to -2.5 (3 centimeter boxes across) it is at 2 on the y axis. What I don't get is what to figure out. My teacher said something about triangles but I don't understand. Also, we have to use the equation y=mx+b as a basis.

I need help quickly please.

I'll try to explain it as simply as I can:

Have you ever heard of rise over run? The idea is, you build a right triangle out of your line, with the height being perfectly vertical and the base being perfectly horizontal. The actual line segment you use is the hypotenuse. It doesn't matter what segment of the line you use, but it's usually easiest to make it so that all of the numbers are whole. If possible, that is.

The next step is determining the slope from that. You go rise/run, or vertical length over horizontal length. remember, if you have a line that goes downwards, the slope is negative. The slope becomes the m in y=mx+b. NOTE: A vertical line has undefined slope. A horizontal line has a slope of 0.

If you don't have a line, but instead have two points that the line passes through, use the following formula: (y2-y1)/(x2-x1). In other words, you take the y value of the second point, subtract the y value of the first point, do the same with x (make sure you keep them in order!), and then divide your new y by x. That will get you your m value.

The second step: determining b. Take one of the points you used to determine the slope. (If you started with the line, just use any point on the line). Multiply the x value from the point by m, and then subtract it from the y value of the same point. For example: If you know the slope of a line is 3, and it passes through (4,17), you go 4*3=12, then 17-12=5. Your b value would be 4. NOTE: You can get a negative value here too. Be careful.

Third step: determine the equation. Take your y=mx+b, and replace the m with your slope or m value, and the b with your b value from above. Remember, if you get a negative value for either of these, you have to designate that. So, from the problem above, you have a slope of 3, and a b value of 5. Your equation is: y=3x+5.

It may look complicated, but it's easy once you practice it.

Can anyone help me write an amazing thesis? Great, I knew you would.

I have to write a thesis about the Shakespearean play Othello and my essay topic is "Iago manipulating Othello throughout the play and how it affects Othello,". My three points within my thesis would be the three paragraphs speaking about the beginning, middle and end of the play. But I can't come up with a proper thesis.

This is really important as the teacher determines the mark of the essay (Or the majority of it) from that thesis alone.

---

This is what I have so far,

Throughout the course of the play, Shakespeare effectively shows a meaningful transition of Othello from a respectable general to a ruthless tyrant due to Iago’s manipulation from the beginning, through the middle and the ending of the play.

I hate it!

Edit:

Version 2

Throughout the course of the play, Shakespeare effectively shows the devastation of Iago’s manipulation upon Othello based on his actions and decisions from the beginning, middle and ending of the play.

[shapu]

You can probably leave the part out about the beginning, middle, and end. After all, the "throughout" covers that.

Well, I need to include what my three following paragraphs will talk about which is the events in the beginning, middle and end.

But, I did manage to fix it and I appreciate your help Shapu!

As homework, I was told to interview an entrepreneur, online or real life. Since I don't really know any entrepreneur in real life, if anyone here is an entrepreneur, or can think like one, please help me answer these questions. (as professionally as possible, truth or fake)

Q: How do you define an entrepreneur?
Q: What qualities do you think are needed to be an entrepreneur?
Q: How much can an entrepreneur earn?
Q: Why did you become an entrepreneur?
Q: Is there any entrepreneur you admire? If yes, who and why?
Q: How experienced were you when you first started?
Q: What are the obstacles commonly faced by entrepreneurs?
Q: Is the path to be an entrepreneur a difficult one?
Q: Are you happy with your work as an entrepreneur?
Q: Do you think anyone can be an entrepreneur?

[shapu]

You don't necessarily need to know an entrepreneur right now. Just find any new business near where you live - and there you go. Has anything that isn't a chain opened up in the last 6 months to five years in your neighborhood?

I don't really know since I'm not the type of person who hangs out often. Anyway, why go through all the troubles when you can make the answers up?

My lecturer told me that I'm free to create an imaginary one, but of course I still wouldn't know how to answer most of these questions.

EDIT: Today I asked the teacher and it turned out that I misunderstood her question. I only needed to write the 10 questions, no answer required

Hence I finished the question before I knew it

People, I need your help!

I'm doing an essay on the October Revolution of 1917 and I need to form some sort of thesis. I'm going talk about the revolution before it began, during and after its reign. I just don't know how to form a thesis which would really end of the first paragraph I have. So far, I have,

The October Revolution has marked a historical turning point for Russia and to this day, it’s affect on the world has been apparent.

I mean, I like the first part of the sentence (The bolded part) but I mean, it's missing something. Can anyone help?

[Hunter Lupe]

Surely you mean effect?

Ignoring the typo, the effect of the October revolution isn't really apparent today (1924 and 1991 are the relatively more interesting years), so the second part of the thesis sets you up to argue for a rather questionable viewpoint.

What's missing in your concept of an essay is the Why? (inability to construct a thesis sentence is usually a sign of that, as a thesis sentence sums up the main purpose of the essay): you want to "talk about the revolution before it began, during and after its reign", a fairly boring way to approach things (you'll end up stating "and then this and that happened because of this and that caused by that guy").
Your prime objective should be to provide and argue for a particular viewpoint, not to restate the facts as written in your history book. Pick a point that you'd be arguying for: whether the October revolution did more good than harm, whether some nasty events could have been avoided if something happened, the October Revolution was unnescersary and undemocratic... anything flies, as long as its an opinion you can argue for.

An essay's thesis is the point the essay is trying to advocate (and perhaps a brief explanation of how you're going to pursue the topic). An example would be:
Subject (unspecific): Pets in Denmark
Topic (narrowed down Subject): The predominance of cats over dogs in modern Danish households
Thesis Sentence: Despite stereotypes of the faithful dog and the faithless feline, a majority of the Danish population now prefer cats because of the living patterns prevalent in modern households.




Alternatively, if it's any inspiration, here's an introduction paragraph to a late-night essay I wrote recently (thesis sentence is last, essay is for my English Lit class):

When the First World War ended on November 11th, 1918, Europeans could breathe a sigh of a relief and welcome the established peace. This peace was not devoid of sacrifices and consequences, though: over 14 million people died, and an entire generation lost the previous century’s optimism. Both texts discussed in this essay are set in a post World War I world – and deal with different aspects of its impact. Through the analysis and comparison of their main theme and inherent message, this essay attempts to establish the psychological impact of the First World War on the people involved.

(Afterthought: I should have specified what sort of psychological impact I was trying to interpret into the works in the thesis sentence as well as the introduction paragraph.)

Yes, it's effect. My bad.

As for the approach to this essay, it's a narrative essay meaning I simply retell what happened before, during and after the October Revolution. I could've taken a more interesting approach to the essay but I found this easier and the fact that I find history dull doesn't help either.
