LORAN, long distance radio navigation for aircraft and ships, uses synchronized pulses transmitted by widely separated transmitting stations. These pulses travel at the speed of light (186,000 miles per second). The difference in the times of arrival of these pulses at an aircraft or ship is constant on a hyperbola which has transmitting stations located at the foci. Assume that the two stations, 300 miles apart, are positioned on a rectangular coordinate system at points (-150,0) and (150,0) and that a ship is traveling on a path with coordinates (x, 75).

a. Find the x-coordinate of the position of the ship if the time difference between the pulses from the transmitting station is .0001 second.

b. Write the equation of the hyperbola on which the ship is located

Pharmacology, all drugs have two names, a trade name and generic name.For example, the trade name of Tylenol also has a generic name of Acetaminophen. Aleve is also called Naproxen. Amoxil is also call Amoxicillin and Advil is also called Ibuprofen.


The FDA has been looking for a generic name for Viagra. After careful consideration by a team of government experts, it recently announced that it has settled on the generic name of Mycoxafloppin. Also considered were Mycoxafailin, Mydixadrupin, Mydixarizin, Dixafix, and of course, Ibepokin.


Pfizer Corp. announced today that Viagra will soon be available in liquid form, and will be marketed by Pepsi Cola as a power beverage suitable for use as a mixer. It will now be possible for a man to literally pour himself a stiff one.


Thought for the day: There is more money being spent on breast implants and Viagra today than on Alzheimer's research. This means that by 2040, there should be a large elderly population with perky boobs and huge erections and absolutely no recollection of what to do with them.

1. A computer is infected with the Sasser virus. Assume that it infects 20 other computers within 5 minutes; and that these PCs and servers each infect 20 more machines within another five minutes, etc. How long until 100 million computers are infected?

2. Evaluate each of the functions below at x = 1, 2, 4, 8, and 16. Plot the graph of each function. Classify each as linear, quadratic, polynomial, exponential, or logarithmic, and explain the reasons for your classifications. Compare how quickly each function increases, based on the evaluations and graphs, and rank the functions from fastest to slowest growing.
- f(x) = x3 - 3x^2 - 2x + 1
- f(x) = ex
- f(x) = 3x - 2
- f(x) = log x
- f(x) = x2 - 5x + 6

The thickness of a soap bubble is only a few molecules. Also bubbles must be > 99% water. (say a cup of water with a few drops of washing up liquid)
However they can last for a couple of minutes. Water just a few molecules thick would eveporate in a just a few seconds. How come bubbles last that long?

So if Michael Jordan's mom had him wherever he was born, and his genes said that he was going to be as tall as he is, but then he was shipped to a place in Africa with meager amnts of food, if he grows up malnutritioned, will he still be as tall as he is today because "genes" decided it for him when he was born?
