Science & Mathematics - 3 December 2007

I saw this on a website. What does everyone feels about it? I believe in the theory of evolution, but reading this has raised some questions in my mind.

“Many evolutionists have tried to argue that humans are 99% similar chemically to apes and blood precipitation tests do indicate that the chimpanzee is people’s closest relative. Yet regarding this we must observe the following: ‘Milk chemistry indicates that the donkey is man’s closest relative.’ ‘Cholesterol level tests indicate that the garter snake is man’s closest relative.’ ‘Tear enzyme chemistry indicates that the chicken is man’s closest relative.’ ‘On the basis of another type of blood chemistry test, the butter bean is man’s closest relative

Would the 7 become 49 in this equation?

5x^3(7x)^2

I have a test tomorrow and I was just wondering... would the ^2 distribute to the 7 and the X or just the X?

Thanks so much!

Right now I'm pursuing a bachelors in math, and plan on getting a masters afterward.
What kind of salary can I expect to make teaching at a junior college?
Am I going to end up a hobo-mathematician?

n parallels lines between themselves are set among m parallels lines between themselves but not with the n lines.
a) How many points are made with the intersections of the lines? (Drawing the situation, I think it's easy to see that it's n.m)
b) How many parallelograms are determinated by the intersections of the lines? (Couldn't do it).
Please tell me if I was right for a), and please explain me the answer of part b. Thanks a lot.

If you have the Square Root of 2 and you multiply it by the Square Root of 2, what do you get?

I'm stuck between 2 x Square Root of 2, Square Root of 4, and Square Root of 2.

The book doesn't tell me how to multiply these very clearly. :(

Does T (the distance between ADJACENT peaks) = P (the period- (timebase x divisions in a cycle))?

So wouldn't that make P = P x time base?
I'm soooooooooooooooooooooo confused :(.
