I have a computer which had vista in it. I want to downgrade it to xp. I have the key, but after I set up the xp, the computer shut down by itself before I can get into windows. So now I think I should buy the vista key because even if I am able to install xp on my computer, it would not work properly anyway. I have a cd which called UPGRADE YOUR WINDOWS VISTA EXPERIENCE.which goes in the package when i bought my vista laptop. the question is if I want to upgrade it to vista ultimate, can I just put this cd in and install it normally or I have to buy the vista basic cd and then buy the key for that Upgrade cd? Thanks a lot for your help

A 0.2417g sample of a compound composed of C,H,O,Cl only, is burned in oxygwn yielding 0.4964g of CO2 and 0.0846g of H2O. A separate 0.1696g sample of the compound is fused with sodium metal, the products dissolved in water and the chloride quantitatively precipitated with AgNO3 to yield 0.1891g of AgCl. What is the simplest empirical formula for the compound.

For all real numbers x and y, let f be a function that f(x+y) =f(x)+f(y)+2xy and such that lim [ f(h)/ h ] = 7 (h-->0)

a) find f(0). Justify your answer

b) use the definition of the derivative to find f ' (x)

c) find f(x)

The graph of y = - 5/ (x-2) is concave down for all values of x such that

x<0 or x<2 or x< 5 or x>0 x> 2
