I know Diesel is not as flammable as gasoline, but what would it take to start a fire with diesel? If I threw a match into some Diesel fuel would it ignite?

Is it because of president Bush being the president the last couple of years that has given the U.S. such a bad profile around the world, or they plain and simply don't like americans?

and how can you re elect such a guy for another 4 yrs. i think it's plain and simple America was afraid of CHANGE.

Grigory Perelman solved one of the great unsolved problems in mathematics, and his work has been backed up by many other experts around the world. He recently was awards a Fields medal and $1 million but turned them down and has yet to come forward.

light light and light dark working together to make 2 universes equal in almost every way. Or how about shadows and light working together to build things? like this (-) and (+) moving like this --> <-- but never actualy connecting because of the fact that there is always emptyness of some amount in between them. Just a random thought maybe someones already had this im 2 lazy to do my research sorry lol. thanks for answers and stuff.

Say you are looking at a stage and see the scene clearly. Next imagine a curtain made of photons falls down. Would you still be able to see the scene clearly? Or would the light from the stage have interference from the light falling down? Imagine you are in space so that reflection off of air molecules is eliminated.

a suspension bridge w/ weight uniformly distributed along its length has twin towers that extend 75 m above the road surface and are 400 meters apart. the cables are parabolic in shape and are suspended from the tops of the towers. the cables touch the road surface at the center of the bridge. what is the height of the cables at a point 100 m from the center? (assuming that the road is level)

thanks for the help.

the u.s.s. independence maintains a constant speed of 10 knots heading due north. at 4 pm the ship's radar detects a destroyer 100 nautical mi due east of the carrier. if the destroyer is heading due west at 20 knots, when will the 2 ships be the closest?
(1 knot = 1 nautical mi/hr)

thanks for the help.

Ok, use Distance formula to find out if pq and qr are congruent. (PQ and QR being line segments.)

P = (4, -4)
Q = (1, -6)
R = (-1, -3)

I got PQ = sqrt 5 and QR = sqrt 1 or 1.

I have the distance formula, but I can't figure out why it's not working. I graphed these, and it's clearly not the correct answers that I have. Help with this and I promise to ask my Geometry teacher. I think I copied the formula wrong.
