The Homework Thread

We've all got that (crappy) feeling when you have a pile of homework staring at you waiting to be done, so on this thread, post your H/W, and then ask others to help out. And NO, this ISN'T cheating, it's asking for help:p
 
History questions are a pain. I might post a hard one that's due in a couple weeks for help.
 
Any help on this question?

"Describe in what way, EACH of the factors changed Canada between 1867 and 1914: Immigration, Technology, Politics, and Globalization. "
 
I would LOVE to have some help for the last 1-2 reasons I posted.

Describe in what way, EACH of the factors changed Canada between 1867 and 1914:politics, and Globalization.

A gr. 8-9 level answer please. Doesn't have to be stunning!
 
I need help with my Social Studies homework. Apparently, Over The Hedge has a lot to do with US history, so I need some help with this question. It is:

The film provides a critique of one way we choose to live today. Is the critique valid? Explain.

I have no clue how to answer this, considering I was taking a little nap when we watched this movie in school. :p All help is appreciated. Thanks.
 
Forgot that I'm one of the only ones from Canada here.

In math, would anyone mind explaining "i" to me and how to solve things like this... -3^(1/2)
 
JacobeTheElf, this would be my answer:
The critique is absolutely valid, as the film shows us humans as being an artificial and invasive society, and that although we know we're killing animals and destroying their habitats, we ignore our destruction by having other humans kill them for us. In the movie, the animals begin to eat human food. It ultimately results in them gaining a ton of weight and becoming extremely lazy. They also give up their standard way of living for the simpler and tastier human food. This, again, shows our destruction, as we know this happens. We know we're destroying the lives of these animals, yet we ignore it and continue to live how we want.

pokemon99, wow, dude, we're learning that in Algebra right now. I'm still learning how to do it, but I might be able to help you eventually.
 
^Thank you very much. I read that question and I was like 'What?...' but it may be due to my lack of attention span (blame it on the ADD).
 
Imaginary Numbers:

i is an imaginary number. The general formula is a + bi. (Complex number)

i^2 = -1

You could also say: sqrt(-1) = 1

When you are graphing these kinds of equations, you graph it in a special way. The x-axis value is indicated by a, while the y-axis value is indicated by b.

9i + 4i = 13i

You combine them together when doing this. Multiplication looks like this:

9i * 2i = 18i^2

Here's simplifying:

4i + 6i^2

Remember that i^2 is equal to -1, so 6 x -1 = -6

4i + -6 = 4i - 6

Basically you just simplify as much as possible like all other equations. You can also solve things like this:

x^2 + 1 = 0

What's x? Since we know that any positive and negative number square is ALWAYS positive, it HAS to be imaginary. We then do the problem like normal:

x^2 = -1
x = i because i^2 = -1

Here's some info on distribution:

5i(2 + 6i)

5i(2 + 6i) = 10i + 30i^2 =
10i + -30 =
10i - 30 =
-30 + 10i (a + bi form of the answer where a = -30 and bi = 10i)

Powers:

When doing powers, you can do fractions too. These fractions are the same as taking roots from numbers.

x to the power of 1/2 is the same thing as the square root of x
x to the power of 1/3 is the same thing as the cube root of x

Here are some examples off the top of my head:

4^(1/2) = 2
8^(1/3) = 2
32^(1/5) = 2

Basically, you can reverse all of those. The answer to the power of the denominator of the fraction gives the original number.

2^2 = 4
2^3 = 8
2 ^ 5 = 32

I can also get into graphing exponential functions/decay and logarithms if you need since those topics are related. Logarithms take it a step further though. If you want to know if you don't already just post. If you haven't covered Logs then I bet you will soon because that usually comes after messing around with powers and roots. (Although you might do some Synthetic/long polynomial division and find roots of polynomials first)


I didn't give the best explanation in the world on either of these topics, so just let me know if further detail is needed and what you don't understand. (I love math :p)


EDIT: Oh and here's how to solve -3^(1/2):

-3 ^ (1/2) = sqrt(-3)

sqrt(-1) = i
sqrt(-3) = 3i

Why?

Well 3i^2 is the same thing as -3, so take the square root of that and you get sqrt(-3)
 
Welcome. CatreBird are you talking about Vectors/Velocity kind of thing? I need a little more of an explanation.
