My sister has to make a presentation about Pedology, appearantly her worksheet provides a list of different studies ("ologies") and a list of descriptions that were meant to match up with those studies. Through use of process of elimination the end result of Pedology according to this worksheet was the study of feet, after about an hour of research I haven't found any hard evidence of this truth, instead I find that its the study of Soil and Child Behavior, somebody please explain what Pedology has to do with feet.

Suppose you represent time on a straight line. Like in geometry when finding the absolute value between 2 points. OK so lets say R equals the rate of time, and its set at 0 on the line. R is in constant motion. Never slowing or speeding up. And the constant motion of R is equal to U, the rate at which the universe expands. So F is the positive number line and P is the negative number line. F representing time to come, and P representing time passed. If you wanted to relive a point on the line, how would you? In my theory, to go back in time or to go into the future is to move forward at a speed to which the universe's expansion is the same at which you started to travel. You move so fast that when you reach the point it's like going there the same time twice. Time creates a dimension with every little bit of expansion of the universe. The smallest amount possible. Which also could be infinite, saying that something is nothing. Coming back to where you started would be hard.

Do you think Pluto should have stayed a planet, or not? why? I think it is reasonable; if they kept it a planet they would have had to add the other small planets like Sedna.

Thanks 4 ev1's help on my last Question! They helped A LOT! *Paul W*

this problem is like the last one but its in a differnt form that i cant figure out....



Write the equation of the line, in slope intercept form, that contains the point (-9,9) and is perpendicular to the line 4x + 2y = -7.



It would really help if you could show all of your work... so i can figure out how to do the problem (like i did the last one)

Thanks again 4 ur help!
