I have the region enclosed by y=x^3 and y = √x rotated about the line x=1.

I'm supposed to find the volume using integration.
The answer in the book is 13pi/30.

However, I keep getting 2pi/5 with respect to y and 5pi/14 with respect to x.

Which, of course, doesn't make sense, because if I was doing this correctly, the answer with respect to either x and y should be the same..right?? uhh..

I don't see what i'm doing wrong.


This is how I started out. A(y)=[ pi(y^2)^2 ] - [ pi(y^(1/3))^2 ]

I didn't think I needed to add or subtract distance because the two functions meet at x=1.

Help please! Ack!

A teacher at a christian school where I also teach was talking to the class about the first and second days of the creation. She asked the question, "Does anyone know what time the day began?" Students ages eight through eleven thought the day began at 12:00 a.m. I guess I am not smarter than a fifth grader, because I thought so too, but she stated in fact the day begins at sunset because of the verse in Genesis, chapter 1:5, "And the evening and the morning were the first day."

I am deciding to place my daughter in an alternative high school for next year after the recommendation of the school district. My daughter has special needs and is failing regular classes as of now. I'm not sure if this is the right thing to do. According to federal special ed laws IDEA, all children who are in special ed and have an IEP plan are FIRST suppose to be in a regular classroom to get the help they need that is listed on their IEP plan. THEN if child is not improving, they put the child in the self-contained classes. Do alternative high schools offer self-contained classes for students with special needs?

A 700 N man stands in the middle of a frozen pond of radius 6.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 1.2 kg physics textbook horizontally toward the north shore at a speed of 6.0 m/s. How long does it take him to reach the south shore?

(im 23 hes 29 weve been engaged for 2 months)i knew he watched it before we moved in together. hes obviously ok with it but im not so much. call me old fashioned, high maintenance, whatever, im a just chick who gets turned off by it. anyways, he volunteered giving it up, even gave away the dvds. but now he just trys to hide it. now its not just about respect and the whole is it or isnt it cheating, now its about honesty too.
we have great sex, he will totally admit to this. he might say i cant really keep up with him but he would also say he wants it all the freakin time.
anyways, its driving me crazy because i know hell never stop, i also know i will never be ok with it.
if he cant change for me should i change for him?? and if so, how do i do it w/o feeling like sh!t?

im 13, this is a poem i wrote about a boy getting drunk. constructive critisim please.

Sitting in a room,
third beer within my klutch.
Feeling guilty now,
promised mom,
"Won't drink to much."
Want to get back to the party,
be with all my friends.
Maybe we can be together when the party ends.
Drinking with the football team,
having quite a ball.
Beginning to fell dizzy,
and then I start to fall.
At first the pain is deep,
for my head had hit the floor.
But the boys begin to laugh,
so I think I need some more.
Going on my eighth and I'm feeling pretty good.
Though I know I've drinken more then I really
ever should.
Then I take the keys,
and being to pull away.
The brutal ending to my life,
on that night in
May.

Do you think that when Bush baby speaks of respect for life he is referring to his political life, which is for more important to him than all of those who's life will be shortened because of the lack of a cure for diabetes. or those who live in pain and suffering because of spinal injury, or those who are disabled because of Parkensen's disease? The overwhelming consensus of the scientific community, not the loony birds who read goat droppings for their so called knowledge, agree that the veto will delay scientific progress for years. Do you think the term "disgusting obscenity' is strong enough?

You can have the same first name if you want, but what would your last name be (or, just make up a whole new name).

Mine would be Graydon Gottrocks.
