Science & Mathematics - 21 December 2006

Outside of the US e.g. Australia, it is simple incremental numbering from one side of the street to the other.
In the US, the numbers often end up in the thousands. I would like to understand the basis for the system - and despite web searching and asking friends, have never found anyone that understood.

Okay, how many noticed that up north, summers are getting hotter and winters warmer. we are also not gaetting any snow. Them When you watch the weather, Florida is getting colder summers and colder winters. They also get snow. This is gradual yes and most might not notice.

I personally think that the planet is turning upsidedown. You know like if you take a map and flip it.

I would like to know what you think about what is happening.

P is any point on the diameter AB of a circle. CD is any chord of the circle parallel to AB. Prove that (PC^2)+(PD^2) is independent of the position of CD.

My friend and I tried several ways to do this question through cartesian system and analytical method and even with vectors but we couldnt come up with a solid proof.

Advice and help greatly appreciated.

But, if you take two steps north and walk in a circle, would it then be considered that you would be going in an eastern or western direction?

I have tanks at different pressures of CO2 and methane. I want to mix them through flow regulators (not pressure regulators) in various proportions. The flow regulators are simple "calibrated bead in tube" type (called "Flow Raters" manufactured by Dwyer). If flow from both tanks is maintained at some level is it possible for gas from the higher-pressure container to enter (backwards through the other 'flow rater') the lower-pressure container? Pressure in both cylinders is similar, but not identical. I would establish flow from the low pressure cylinder first, then the high-pressure cylinder, and shut off the high pressure cylinder first. Again, I can regulate flow rate (in scfh) well enough for my purposes, but have no way of regulating pressure.

ok...4 easy questions....wanna check my answers to see if theyre right...thanks to anyone who answers meaningfully...

#1-Are earthquakes random or do they have a pattern to their locations?

#2-Are volcanoes random or do they have a pattern to their locations?

#3-How are the locations of Earthquakes and Volcanoes related? Why is this?

#4-How does the evidence ok patterns in crustal activity support the theory of plate tectonics?

their so easy i think i overthought them and got them wrong...hahaha

If f(x)=x^3+1 and if f^-1is the inverse function of f, what is f^-1(4)

So is that correct the inverse is the cube route of (x-1), so therefore the answer is cube route of 3?
