We just learned that PERMUTATIONS are just an application of fundamental counting priciple. We also learned that COMBINATIONS are just an application of PERMUTATIONS and the counting principle. Question: Can you say that COMBINATIONS are also just an application of the counting principle?

obviously the parenthesis are not in this problem. but i know of no other way to represent a with the n in lower case slightly below the n and the 1 over 2 with the lower case n to the upper right of the 2.

Consider the equation v=1/3zxt^2. The dimensions of the variables x, v, and t are [L], [L]/[T], and [T], respectively. What must be the dimensions of the variable z, such that both sides of the equation have the same dimensions?

Can someone work through the problem so I can understand the process?

I can't seem to figure this one out! I am sure I'm making it more complicated than it is.

A motorboat can maintain a constant speed of 16 miles per hour relative to the water, and make a trip upstream in 20minutes; the return trip takes 15 minutes. What is the speed of the current?

After much hesitation, I have decided to buy the Texas Instrument TI-84 Plus SE Graphing Calculator. Where should I purchase it from? (cheaply and reliably) Do these things break down easily and need to be fixed/returned sometimes? Should I buy online (which might be cheaper) or at a 'local electronics store'? If online, which website?

Thanks!

A highway is being built between two towns, one of which lies 35.0 km south and 72 km west of the other. What is the shortest length of highway that can be built between the two towns, and at what angle would this highway be directed with respect to due west?

The answers are 80.1 km and 25.9 degrees south of west, but I need to understand the process.

A spider bite...please read...........


And you thought the brown recluse was bad!!!

Three women in North Florida , turned up at hospitals over a 5-day period, all with the same symptoms. Fever, chills, and vomiting, followed by muscular collapse, paralysis, and finally, death. There were no outward signs of trauma.
Autopsy results showed toxicity in the blood. These women did not know each other, and seemed to have
nothing in common. It was discovered, however, that they had all visited the same Restaurant (Olive Garden) within days of their deaths. The health department descended on the restaurant, shutting it down. The food, water, and
air conditioning were all inspected and tested, to no avail.

The big break came when a waitress at the restaurant was rushed to the hospital with similar symptoms. She told doctors that she had been on vacation, and had only went to the restaurant to pick up her check. She did not eat or drink while she was there, but had used the restroom. That is when one toxicologist, remembering an article he had read, drove out to the restaurant, went into the restroom, and lifted the toilet seat.

Under the seat, out of normal view, was a small spider. The spider was captured and brought back to the lab, where it was determined to be the Two-Striped Telamonia (Telamonia dimidiata), so named because
of its reddened flesh color. This spider's venom is extremely toxic, but can take several days to take effect. They live in cold, dark, damp climates, and toilet rims provide just the right atmosphere.

Several days later a lawyer from Jacksonville showed up at a hospital emergency room. Before his death, he told the doctor, that he had been away on business, had takena flight from Indonesia, changing planes in Singapore , before returning home. He did not visit (Olive Garden), while there. He did, as did all of the other victims, have what was determined to be a puncture wound, on his right buttock.

Investigators discovered that the flight he was on had originated in India The Civilian Aeronautics Board (CAB) ordered an immediate inspection of the toilets of all flights from India , and discovered the Two-Striped Telamonia
(Telamonia dimidiata) spider's nests on 4 different planes!

It is now believed that these spiders can be anywhere in the country.

So please, before you use a public toilet, lift the seat to check for spiders.
It can save your life!
And please pass this on to everyone you care about.
