Giveaway of the Day - Equation Wizard 1.2

The program allows you to solve algebraic equations in the automatic mode. You just enter an equation in any form without any preparatory operations. Step by step Equation Wizard reduces it to a canonical form performing all necessary operations. After that it determines the order of the equation, which can be any - linear, square, cubic or, for instance, of the 7-th power. The program finds the roots of the equation - both real and imaginary.

I understand the pharmacology of morphine and fentanyl (structure, binding sites, differences in mu-, delta-, and kappa- opioid occupancy and potency) so I would like the following question to be answered in the *clinical* context (I'm an RN who works in a Neurosurgical ICU with mainly vented patients):

In your clinical experience, which of the two (morphine or fentanyl) have you found to be the better analgesic with the least potent respiratory depressant action?

(Thank you)

Many stars in the Orion constelation have crosses, spheres, with spiral patterns in their visual photos. The crosses appear to be lense flares, but are the circular spheres real or part of the lens flare; as viewed with SkyView Virtual Observatory at http://skyview.gsfc.nasa.gov/

With the fact that charcaricadon megalodon a type of ancient great white shark was about 50 foot long, plus the recent find of an ancient wombat jawbone put the size of the wombat at 5-8 times the size of modern day wombats, given the find of fossilised dragon flies with 50 inch wing spans, and fosislised giant spiders "megarachne servani" with a body index of 1.5 foot, is it fair to say that since the creatures on earth now are dimunitives in comparison, that we and the animals on this planet are quite clearly devolving and not evolving. There are so many examples of larger more powerful creatures, their modern day equivalents are tiny in comparison

Further, if an ancient form of man existed, in comparison to other ancient creatures to their modern day equivalents, is it not fiar to say he would have been a lot bigger than he is now, whatever allowed that wombat, that spider and that shark to be gigantic, why would not that have allowed the so called comman ancestor to be huge too?

Seeing as fossils are not actually dated by carbon dating, but by their position in the geological column, and how the geological column is dated by the fossils that are found in it, can we really cliam the earth is millions of years old?

The geological column was invented by hutton and lyle in the 1850's. They asssigned layers and fossils with ages of 70 million years old and more.Such as the happily seen swimming calelocant. Seeing as they did not possess any scientific techniques in the 1850's to date anything even up to 250,000 years, how can we still rely on this geological column when it's a flawed scientific standard of over 150 years.

The fossil record is not concrete proof of anything evolving, it's concrete proof of fossils. They have found fossilised hats and cowboy boots, indicating that fossilisation and petrification is a process that requires certain conditions and not millions of years

Use unit vectors to express the vector C, where C = 3.00 A - 4.00 B

I figured out some of the problem I found A to equal 1.41i + 3.31 j and I found B to equal -2.08i + -1.2 j

* but I cant figure out how to find C, and once I find Vector C's i and j, I then need to find the magnitude and direction of C.......... Lost, Phsyics is hard,

Hello. This problem is for homework and it's not graded for correctness, but I don't know how to solve it and it's quite bugging me. I've even asked my math tutor and she wasn't sure either... T__T
This is a problem from Calculus AB, in the chapter titled "Logarithmic, Exponential, and Other Transcendental Functions"

Here is the problem:
Air pressure~
Under ideal conditions, air pressure decreases continuously wiht height above sea level at a rate proportional to the pressure at that height. If the barometer reads 30 inches at sea level and 15 inches at 18,000 feet, find the barometric pressure at 35, 000 feet.

*I tried using proportions...but that wasn't the right answer. According to the book, the correct answer is "about 7.79 inches"
Thank you very very much in advance!
