The beach is x kilometers away . You drove to the beach at a rate of 60km/hr. How fast would you have to drive back to have gone the whole round trip at an average speed of 120km/hr?

I'm posting this in reference to another question I answered as a demonstration.

Last night I was walking out from my friend's cottage on the beach and I was looking up when what appeared to be a shooting star flashed across the sky. The weird thing is it did not travel across the sky, but more like from up to down. It didnt travel very far either, it was a quick flash but it was amazing none the less, I've never seen a shooting star before. I know there was supposed to be a meteor shower this week so I'm wondering if it was part of that or a shooting star. Can anyone help me?

BARCELONA (Reuters) - "Galactic Suite," the first hotel planned in space, expects to open for business in 2012 and would allow guests to travel around the world in 80 minutes. Its Barcelona-based architects say the space hotel will be the most expensive in the galaxy, costing $4 million for a three-day stay. During that time guests would see the sun rise 15 times a day and use Velcro suits to crawl around their pod rooms by sticking themselves to the walls like Spiderman. Company director Xavier Claramunt says the three-bedroom boutique hotel's joined up pod structure, which makes it look like a model of molecules, was dictated by the fact that each pod room had to fit inside a rocket to be taken into space.

If one is given, sin^2x one can change that into (1-cos^2x). If one is given sin^4x one can change that into (1-cos^2x)^2. So if one was given sin^5x, would one change that into (1-cos^2x)^5/2...if not plz explain what one must do to change sin^5x into the (1-cos^2x) form. Therefore, what would be the general rule?

I know I can graph circles using the standard equation when the circle equation is simple like x²+y²=1,where the center is at (0,0), and I put √(1-x²) and -√(1-x²) into the calculator,

but once the equation gets complicated with the center somewhere else besides the origin, I don't know how to write it into the equation.

For example: (x-2)²+(y+1)²=1, I know how to graph manually with center at (2,1), but how do I graph this on a scientific calculator?

I know I have to get "y" by itself by subtracting (x-2)², but do I take the square root then subtract the one or vice versa?

I know this is a bit long, but any help is appreciated. Thanks.
