Calculus Solids of Revolution?
Find the volume of the solid obtained when the specified region is rotated about the given axis.
1. Bounded by y=x^2+1, y=9-x^2; about x=2.
2. Bounded by x=(y-3)^2, x=4; about x=-1, then about y=1.
I know the answers to the problems, but what trips me up is if I should use the washer method or the shells method. How do I go about finding what method to use for which question? Thanks!
1 AnswerMathematics7 years agoCalculus Pump Problem Finding Work?
An upright cylindrical oil tank is buried so that it's circular top is 10'. The tank has a radius of 5' and a height of 15'. The oil level is at 6' in the tank. Given that the density of oil is 50 lb/ft^3, calculate the work required to pump all the oil to the surface.
I know you create an xi value, have it grow infinitely smaller, and integrate. How do I do that in this scenario to find the work? Thanks!
1 AnswerMathematics7 years agoWhat exactly is up with my pinky?
Some strange thing is happening to my left hand's pinky.
When you look at the hand inside facing you, you notice that each finger is divided into "three parts", the top, middle, and bottom. My pinky has this weird, red bulge sticking out on the side on the top of the middle portion. Now it feels like its swelling.
When I curl my pinky, it feels like there is a band-aid on it, but there isn't. O_O
What is up with it?

7 AnswersOther - Society & Culture1 decade agoSo... what about jury duty?
I know that jury duty is like... you get called in to a court trial and you decide the verdict and whatnot...
Is there more to that?
For instance, say, the person is not found guilty, but the trial, somehow gets called back into court. Does it call for an entire new set of jurors or the same ones?
Thanks in advance. :D

5 AnswersNewborn & Baby1 decade agoPokemon: Is there a way to EV train at level 100?
I just received a shiny, Hardy Gliscor over wi-fi. I looked at the stats and compared it with charts from Smogon and Serebii and I see that it has not been EV trained.
I've done some researching and some say you get the 4 points, deposit it into a box, then it will get the stat. Is this true? Is there an alternative way?

2 AnswersVideo & Online Games1 decade agoSomething is wrong with my DS Lite...?
My DS Lite was bought in April of 2007. And now, I was just playing, then all of the sudden, my touch screen started twitching. Up and down, up and down continuously and quickly too. It was like it was having a seizure.
Does anyone know what's wrong with it?
My touch screen isn't in bad condition. It just started to move up and down, and as mentioned before, like twitching.
Thanks in advance.
PDAs & Handhelds1 decade agoPokemon related: A question about Psych Up...?
I know that Psych Up copies foe's stat changes. Like when a pokemon uses Swords Dance, you can copy the change. I have a few questions.
Say Umbreon was intimidated by Gyarados. Would Psych Up revert Umbreon back to regular attack?
Also
Say Slowbro used Amnesia. Then a Ninjask used Agility. If Slowbro used Psych Up on Ninjask, would the Amnesia bonus drop, or stay?

2 AnswersInfectious Diseases1 decade agoNasal passage problems...?
This morning I've woken up at 3:10 because my very dry nasal passage(deep back, like near the throat) woke me. I snore when I sleep and sometimes I wake up due to a dry mouth, tongue and deep within the nose. I don't understand this. And when I am awake, my nose, once again talking about the far back of the nose, get's really, really clogged, and I have to switch sides I lean on to be able to breathe through my nose. I'm not sure if this is allergies or something. And now throughout the day, my neck has been hurting. Does this tie together at all?
How can I prevent/cure this? And would a jala neti be effective here?
Thanks in advance.

1 AnswerRespiratory Diseases1 decade agoPOKEMON! Why do people say Spiritomb has no weakness?
I don't understand this... Spiritomb has but ONE weakness. That is FIGHTING. All you need to do is use Foresight/Odor Sleuth. I've tested this and guess what? Super-effective! Now you know, just wanted to clear this up. Kind of annoying when people type, "Spritom has no wekness".
Oh yeah... first person replying gets free 10 points... xD
Unless I forget about this question and someone else selects their's.
