a piece of wire 60 inches long is cut into six sections, two of one length and four of another length. Each of the two sections having the same length is bent into the form of a circle and the two circles are then joined by the four remaining sections to make a frame for a model of a right circular cylinder of, as shown in the accompanying figure.

-find the lengths of the sections that will make the cylinder of maximum volume

- justify your answer

Humans oxidize glucose in the presence of O2. For each mole of glucose oxidized about 686 kcal of energy is release. this is true whether the mole of glucose is oxidized in human cells or burned in the air. A calorie is the amount of energy required to raise the temp of 1 g of water by 1'C ; 686 kcal=686,000cal. the average human requires about 2,000 kcal of energy per day, which is equivalent to about 3 mol of glucose per day.

I suddenly ran into a problem I've never seen before...a variation I suppose? I have no idea how to work this one out, but some other guys say they found a solution, but right now, I'm thinking no solution...here's the question:

BTW: ~ is the integration sign (sorry I don't know how to do it on comp) so 1~2 would mean integrating from 1 to 2.

Let:
1~2 f(x) dx = -3,
1~5 f(x) dx = 5, and
1~5 g(x) dx = 9.

Find: 1~2 (3 f(x) +1) dx.

I've done tons of just integration with these kinds of problems, but I've never seen one where there is a constant inside...how can you solve this? Others say the answer is -8.

I thought it was 50%. Half the Moon would be lit and it would be "full". A program I have that shows the current stage of the Moon has gone past 50%.

Alright, basically I want to know if alternating current applied to an electromagnetic coil near a magnetic field pulsing at the same frequency will boost the magnetic field more than the electromagnet alone would. Also, would an alternating magnetic field, when spun fast enough, create a slight repelling force?

According to www.wikipedia.com the term supersaturation refers to a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. It can also refer to a vapor of a compound that has a higher (partial) pressure than the vapor pressure of that compound.
