I've already figured out how to find the current through resistor a, but I can't figure it out for resistor b, and I really need that part to finish the rest of the problem. please explain!! thank you!
The aluminum wire in a high-voltage transmission line is 2.7 cm in diameter. It is designed to carry a current of 1100 A.?
The aluminum wire in a high-voltage transmission line is 2.7 cm in diameter. It is designed to carry a current of 1100 A.
What is the voltage drop across a 12-km-long segment of this power line? Please explain.

can someone please check my answers and make sure I got these right, because I'm pretty sure they're right but I really don't want to get any wrong.
1. What is the value of d/dx [f^-1(x)] when x= 2, given that f(x)=x^3+x and f^-1(2)=1?
my answer: 1/4
2.What is the value of d/dx [f^-1(x)] when x= -2, given that f(x)= ³√(1-x) and f^-1(-2)=9?
my answer: -12
3. What is the value of d/dx [f^-1(x)] when x= 0, given that f(x)=x/(1-x) and f^-1(0)=0?
my answer: 1
4. What is the value of d/dx [f^-1(x)] when x= π, given that f(x)=2x+sin x cos x and f^-1(π)=π/2?
my answer: 1
5. What is the value of d/dx [f^-1(x)] when x= 2, given that f(x)=(2-x^2)/(1+x) and f^-1(2)=0?
my answer: -1/2
A cylindrical tank shown is half full of a certain fluid that weighs 12 pounds per cubic foot. Find the work done in pumping the fluid out of the tank from the top outlet
I know the equation you would use would be this: http://i41.tinypic.com/2dqkgus.jpg but what goes in the equation for (a) and (b) and f(x)?
What is the volume of the solid whose cross-sections are equilateral triangles perpendicular to the x-axis and with a base on the region bounded by curves y= x, y= -x, and x= 1.
Please explain, because I really need to know how to do this for the rest of my homework.
How do you know when to use dx or dy when doing a problem like this...
Find the volume of the solid of revolution obtained by rotating the region bounded by x = 1, x = 2, y = x^3, and y = 5x + 2 about the y-axis.
should the problem be set up like this
because I've tried doing the problem both ways and I'm not getting any of the answers on my homework so I think I might just be setting it up wrong.
the answers are:
What is the volume of the solid of revolution obtained by rotating the region bounded by y=√x and y=x^2 around the y-axis?
Every time I try this problem I get something like π(x-x^4) and that is not one of the choices on my homework, so can someone please help? :)1 AnswerHomework Help9 years ago
I'm looking at buying a Seagate FreeAgent GoFlex 1 TB USB 3.0 Ultra-Portable External Hard Drive and I was wondering if this would work since my USB ports are 2.0. If it does work would the 3.0 cord even make a difference, like would it be faster than if it was a 2.0 cord?2 AnswersOther - Hardware9 years ago
can anyone please help with any of these problems?
1. simplify cot^2x(sin^2x)
2. simplify tan^2x csc^2x-tan^2x
3. simplify (sec x-tan x)^2
4. verify 1/tan x csc x sin x=cot x
5. verify cos^3xsin^2x=(sin^2x-sin^4x)cos x
6. solve 4 cos x=1+2 cos x
7. solve 1/2sec x-1=0
8. find all solutions in the interval (0, 2π). 2 sin^2x-3 sin x=-1
9. find the exact values of the sin, cos, and tan of the angle by using sum or difference formula. 345degrees=300degrees=45degrees

Okay so for biology I have to do a project on a endangered animal and mine is the asian leopard cat. here's a picture if you want to see it: http://www.dicapriobengals.com/Asian_Lleopard_cat_...
Anyways so I have to make a pamphlet the uses as much factual evidence and information as possible and suggestions as to what one could do to help the animal. So my question is does anybody know how to create a pamphlet for that. Like what should I have on each side of the pamphlet. Also what kind of information should I use. If anybody answers this question and gives me any information with it, can you please send me a link to the website you used, because I have to make a Works Cited page with it.3 AnswersHomework Help1 decade ago
