Science & Mathematics - 26 November 2007

I have no clue where to start here.

if we know that (3.5,-30.25) is the vertex of the parabola below, figure out 3 more points that would also be on the parabola. Explain how you know that your 3 points are on this parabola even though we don't know it's quadratic equation.

Other points already given on parabola besides the (3.5,-30.25) are (4,-30) (6,-24) (10,12)

I'm stressing out trying to solve this.

I saw this 2 years ago on christmas eve. The thin ring of light was not anywhere near the moon, because the circumference was so large it went took up the whole sky that was visible to us. However the moon was directly in the center of it. Basically the scene looked like if you drew a very large circle for the ring and then in the center drew a very small dot for the moon. What could this be????

Personally i don't believe in evolution because i believe that the awesome and almighty God created the world. i have reason to believe that because of a lot of stuff that i'm learning abt evolution and its counter arguements. here's some:

irreducable complexity - says that substances and particles couldn't have evolved because they need all their parts to work. If one of the parts is missing, then it cannot work, so mutations cannot support this theory. example: flagellum motor - research michael behe (darwin's black box)

mutations - almost all mutations are bad. if evolution is true then almost all the things that we see today, would have had to come from billions and billions of mutations. yeah, evolution says that it took billions and billions of yeas for these to occur, but why are we not seeing mutations and evolution today?

More: how do u explain entropy, DNA (which is crazy!), cambrian explosion - when fossils of different animals appeared at same time, teleology etc ?
