There are positive integers a, b, and c that solve this system of two equations:
c^2 - a^2 - b^2 = 101
a*b=72
What is the value of a + b+ c?

Something, I'm assuming a rat or mouse, has apparently died in the insulation under my house. I think its on top of the heating ducts, stuck under the floor in the insulation. I can't locate it and the smell is really bad. Fortunately it's not affecting the entire house. Very unfortunately, the room affected is my bedroom! We have incense and glade plug ins all over the place but I'm wondering how long we're going to have to wait it out before its not so funky in there anymore.

The scientific name for the clap, in which you hit your hands together to produce a sound? I've looked online everywhere, and it refers to different plants, but not the right answer I'm looking for.

Are there any web sites that have full episodes of Fashion House or Desire? I've already ruled out YouTube and Dailymotion. I would be interested in web sites that offer written reviews on these shows as well but prefer a video. Thanks.

Thanks to everyone on the last one. We got through about five more problems after that.

prove that the function x*sinx is not uniformly continuous on the real numbers

do you just negate the definition and prove it from that or use a proof by contradiction...?

I'm serious. A friend asked me and I didn't know the answer. If, on an evolutionary scale, a man's testicles are the most important organ in his body, then why are they not protected within it? They may not be important to an individual life, but they are essential to the continuation of the species.

Even if it's a profound void, wouldn't that void require an area to occupy?
And if there IS such a thing as extra-Universal space, wouldn't that open up the possibility of multiple Universes existing in that extra-Universal space?

A solution is prepared by dissolving 0.050 mol of HCN and 0.025 mol NaCN in 100 ml of water, what is the pH?

Okay, I know to redo molarities so HCN--> .5 and NaCN--> .25
pH=-log (H)^(1/2)

but NaCN is a salt right.. a neutral salt so pH= 7.0

The answer is 8.91 but I cant seem to get the process help!!!

I'm having trouble with this one...I don't understand why f(x) isn't 3 - (x/4) - sqrt(x+9)? That's the right answer, right?

Consider the area between the graphs x + 4y = 12 and x + 9 = y^2.

integral from 0 to -9 of f(x)dx + integral from 40 to 0 of g(x)dx


f(x) = ?
g(x) = ?
