Suppose that (gºf)(x) = 3x+7. Find g(x) if f(x) = 4- 11x. Find f(x) of g(x) =4 -11x. I know that the answers are g(x) = (-3/11)x+ (89/11) and f(x)=(-3/11)x - (3/11) but I don't know how to solve this problem or what to look up on the internet to find information.

Why do they always show glaciers calving as evidence of global warming? It suddenly occurred to me that glaciers can only calve if they have reached the sea and are moving downward; which means that they must be growing! What's the deal? When glaciers melt don't the "retreat"? I'm confused.

I've heard a lot of talk of the World ending in 2012. Apparently the Mayan calender ends in 2012 plus concerns over an upcoming reversal of the Earth's and maybe the Sun's magnetic fields in 2012. Any truth to all this talk?

I am an amat gold prospector and found that a mix of regular table salt and venegar makes a good cleaning solution for small (tiny) amounts of ore.

I have placed a small amount of ground ore into a solution of salt and vinegar and then added a very small amount of mercury to help retrieve the gold particles.

What I am seeing is that over time, gas bubbles appear on top of the blob of mercury.

Anyone have an idea of just what kind of reaction is going on here? Is this something I should be concerned with?

BTW, the solution, ore, and mercury are in a well sealed vial.
