Sorry for the late response! I’m currently at a camp with terrible reception. I have it all sortrd now, thank you for offering suggestions and help!

As tourism or migration? I'll try to answer migration. A better monthly-gain/salary, better education, better hospitals/health centers etc., better jobs, social construction and culture. Also, being safer plays an important role too.

YOUR QUESTION:What is the area of a right triangle with the given vertices?

(3, 1), (5, 4), (6, −1)
Enter your answer in the box.

Can someone explain how exactly to get the answer to this? I'm having trouble with this subject...

Ok, so, to start off with it would probably be helpful to visualise the triangle. Here are the points plotted and made into a right angled triangle:

I've also labelled the points:
-Point (5,4) is A
-Point (3,1) is B
-Point (6,-1) is C

In order to find the area of a right angled triangle, you need to multiply the height with the width and then divide by two. The height and width are the lines AB and BC.
We can find the lengths of these lines using Pythagoras' theorem (a squared + b squared = c squared). c squared will give us the length of AB.
For the line AB, we find a squared by finding the difference between the x co-ordinates of points A and B, and then squaring it.
So 5 - 3 = 2, and 2 squared is 4, giving us a squared as 4.
Then we find b squared by finding the difference between the y co-ordinates of points A and B, and then squaring it.
So 4 - 1 is 3, and 3 squared is again 9, giving us b squared as 9.
Using Pythagoras' theorem, we can then know that 4 + 9 is c squared. Therefore c is the square root of 13.

We can then repeat this process with the line BC.
a squared will be 6 - 3, giving us 3, which we square to give nine.
b squared will be 1 - - 1, which turns into 1 + 1 giving us 2, which we square to give 4.
Therefore the length of c squared will be 13, so the length of AC will be the square root of 13.

Now we have the lengths of both AB and BC, we can find the area of the right-angled triangle.
The area of right angled triangle is the width (BC) multiplied by the height (AB), which is then divided by 2.
Multiplying the square root of 13 (BC) by the square root of 13 (AB) gives us 13.
13 divided by 2 gives us 6.5 .

Therefore the area of the right angled triangle is 6.5 units squared (which you can probably just give as 6.5 given it looks like you're answering this online).

Hope this helped, and that this is the method you're used to & I haven't just confused you more? :)

I HAVE A QUESTION!
TYPE OF QUESTION:(answer here e.g.. Math, sciences) Geology
YOUR QUESTION:(write here)

Does anyone happen to know about the Pinnacles in Western Australia?
I've noted that there are three theories as to how the limestone pillars formed, but I'm only fond of one of them. I've read sources about the other two but am extremely unsure of what they mean as the explanations are vague. Is someone able to explain them to me, if anyone knows?

If not, that's alright. Thank you so much.

If you let me know what you're confused about specifically, I might be able to help. I've got a couple of degrees in geology. Off the top of my head, I don't think I've ever looked into any Australian formations that much, as that's not where I'm based, but if you could give more information, then I might be able to help sort it out with you.

YOUR QUESTION:The question says to multiply (5x-4)^3 I know you FOIL but I don't know how to apply it to an exponent of three
Thank you for the help

At the beginning, you have (5x - 4)(5x - 4)(5x - 4).

Start by multiplying two of the factors, so (5x - 4)(5x - 4). You can use FOIL for that, and should get (25x^2 - 40x + 16)

You then have (5x - 4)(25x^2 - 40x + 16). You want to distribute the (5x - 4), so multiply each factor of the (25x^2 - 40x + 16) by 5x, then multiply each factor by -4.

That should get you 125x^3 - 200x^2 + 80x - 100x^2 + 160x - 64

Combine like factors, and you have 125x^3 -300x^2 + 240x - 64

Hope that made sense! Feel free to ask more questions if anything confused you c:
