I always end up with 5 which of course does not make sense. Are there flaws with my algebra?

Find the volume of the solid obtained by rotating the region in the first quadrant bounded by the curves

is inflated at a rate of 14cm/s
(a) Express the radius r of the balloon as a function of the time t (in seconds). r(t)=t/14cm/s

(b) If V is the volume of the balloon as a function of the radius, find V r.

4/3pi(t/14cm/s)

not sure if that is right? do I divide t by the inflation rate?

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

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

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?

This is driving me nuts. Any math wizz answer this for me please:

Why am I getting different deviation values when I work it out on paper than when I use excel. Heres the problem:

Average: 50.08
5 tests: 50.11, 50.08, 50.10, 50.07, 50.05

By hand I get: .0239791576
With excel I get .023874673

Am I working this out right? What did you get when you did both? Thanks in advance.
