If a cord is plugged into a receptical (outlet) there is electricity inherent ... I know that breaking the circuit stops the flow but I also know that current doesn't run back into the outlet, so what happens to it? does it just disappear?

Find the slope and y-intercept of the line represented by each of the following equations

2x+5y=10

2007-08-29 15:20:14 · 11 answers · asked by Anonymous in Mathematics

Directions: Write an equation in slope intercept form for the line that satisfies each set of conditions.

1.) slope 0.25 passes through (0,4)
2.) passes through (-3, -1) parallel to the line that passes through (3,3) (0,6)

I don't have the first clue where to start with these, if you could work it and show me steps on how to get the answers. Thanks

Integrate; indefinite: (x^4)(sqrt(x^5 + 1))dx

definite: 0(lower limit) to 1(upper limit): (x^2)/(x^3 + 5)dx

definite: e to 9: ((ln(x))/x)dx

indef: tan(x)dx "no formula"

indef: sqrt(x)e^(x(sqrt(x)))dx

indef: x(2x + 3)^3 dx

please list all steps

i have some practice questions on dimensionally correct equations that i just can't understand.

1. v^2 = v0^2 + 2ax

and

2. x = v0t + 1/2 * a^2 * t^2

i know x =length (L)
and a = acceleration (L/T^2)
and v & v0 = velocity (L/T)
and t = time (T)

i just don't understand how to put everything together.work would be appreciated due to the fact that i'm trying to figure out how to do this problem, i don't want just the answer. THANKS! :)

There is a log cabin, somewhere in the woods filled with republicans and democrats. One day, one of the democrats decides to become a republican. at that point there were equal numbers of republicans and democrats. the very next dy he decides to become a democrat again. then another republican becomes a democrat. at that point there were twice as many democrats as there were republicans. The democrat became a republican, and everything was back to normal. how many republicans, and democrats were in that log cabin?

Hi,

I have read so many articles about plants being emotional and conscious.
But they don't have a nervous system or a brain.
How can this be?

PLEASE DO NOT ANSWER WITH LINKS.

Thanks
