Science & Mathematics - 3 November 2007

This is what I did:

1. x'=(4)x^(1/3)-(1/16)x^(-1/3)
2. integral of (sqrt(1+(x')^2)
3. integral of (sqrt(1+(4097/256)y^(1/9)-(1/2)y^(-1/9) )
4. integral of ((sqrt(1+(4097/256)y^(1/9)-(1/2)y^(-1/9) ) from 5 to 10

can anyone tell me what am I doing wron here???

I have been having trouble with these two sections of Algebra II, so if you could please explain the following problems it would help me understand what I am suppose to be doing:

IF YOU CAN PLEASE TRY TO ANSWER ALL THREE, BUT IF NOT AT LEAST ONE

1) The top of a 15-foot ladder is 3ft farther up a wall than the foot of the ladder is from the bottom of the wall. How far is the foot of the ladder from the bottom of the wall?


2) The side of a large tent is the shape of an isosceles triangle whose area is 54 ft^2 and whose base is 6 ft shorter than twice its height. Find the height and the base of the side of the tent.

3) A farmer plans to use 21 m of fencing to enclose a rectangular pen having area 55 m^2. Only three sides of the pen need fencing because part of an existing wall will from the fourth side. Find the dimensions of the pen.


NOTE: Section is called "Problem Solving Using Polynomial Equations"

Thanks.

I'm sure many of you have been following the news about the International Space Station. About a week ago, I think it was, while they were unfurling one of the solar panels, they found one of them had a tear. But just recently, Scott Parazynski successfully repared it.

But I was wondering, is that a perminent repair? Or will the ISS need to get a new solar panel to replace that one at its earliest convenience? I understand it's fully operational now, but doesn't that repared section have a greater chance of being damaged in the future than pieces of solar panel that never broke?

a) y = sin X tan X
b) y = sin^3 x + sec x
c) y = cos (x^2 + x + 2)
d) y = sex (1/squareroot x)

Please explain to me how I could approach this? I've read my text book and it is not helpful at all.

Also, could you possibly explain

e) Find the equation of the tangent line to the graph of y = sec(3x) at the point with x = pie/12

Thank you.
