According to Boyle's Law, when a sample of gas is compressed at a constant temperature, the pressure and volumn satisfy the equation P V = C, where C is a constant. Assume that, at a certain instant, a sample has a volume of 950 cm3, is a pressure of 120 kPa, and the pressure is increasing at a rate of 19 kPa/min. At what rate is the volume decreasing at this instant?

let matrix A=[ 1 1 ; 4 1]. (A 2x2 matrix with (1 1) in first row and (4 1) in the 2nd).
Diagonalize A by finding P and D such that A=PDP^-1.

Hence compute A^50.

Is it true that A^-1=(P)(D^-1)(P^-1)

please try to send me the final answers as well as the workings... thanks :)

It is possible to open a 3rd eye through meditation, right. But how are you going to close the 3rd eye if you don't want to experience parapsychological phenomena with spiritual encounters? Once, the 3rd eye is open can't you close it?

Just the other day I found a note that my husband wrote. It reads as follows: "The bearer of this note is trying to tell you where a booby trap or a mine is located, if he does you should reward him kindly." There is a picture of an explosion on the note. I know he knows what he`s talking about because he blew up an owls nest a few years back which was near the place he was working--he`s Native American and they just don`t like owls.

rich and poor,young or old everyone needs numbers.mathematices,the queen of science,in its practical application is a part and parcel of our lif.mathematics also help in to devolop their aptitude,imaginaton and logical reasoning.often children study maths just to scour marks and pass in the examintion without enjoying the subject.to do away with this unhealthy practice we should present mathematice in an attractive and interesting way.this contents would benefit childrens as will as elders.

Hello. In my chemistry class we were talking about boiling points and pressure. My instructor brought up this question: why does it take longer for an egg to cook in Colorado than in NY? I understand that Colorado is at a higher elevation, but I do not understand how that relates to cooking time. I think this is a simple concept to grasp, I just don't understand why I can't seem to grasp it. Please, with not a bunch of confusing chemistry jargon or equations, SOMEONE BREAK IT DOWN FOR ME!!!
