Mathematics - 5 November 2007

During the college registration, 442 students registered for Computing, 187 registered for Business, and 234 registered for Mathematics. What is the greatest possible total number of different students who could have registered for these courses, if known that only 96 registered for both Computing and Mathematics?

Recently I ran across a math term and now I've forgotten it.

What is the term used for objects that you can fit together perfectly where the edges match up and there are no gaps? For example, rectangles qualify, since you can make an area completely covered using them. Circles do not, since there will be gaps in between them as you can not match up all the edges.

Hi!!! I've tried this 7 times, and I keep getting 439 N as my answer, but I know that it is wrong... The book says that the answer is 929 N.

K, the overall question is that there are two forces, one being 600N and the other being 410N that form a 47 degree angle between them. Find the magnitude of the resultant and the angle that it forms with the larger force.

I can't really copy over my drawings, but I'm pretty sure that they're all right because I keep getting the same answer! Can someone PLEASE explain to me how to get the answer for this?? I know that the reason why I'm getting the ANGLE wrong is because I'm getting the magnitude wrong, so even if you can just help me with the magnitude, I can probably figure out the angle! :)

Thank you so much! I'll pick a best answer TODAY!

The average value of a certain type of automobile was $14,040 in 1994 and depreciated to $4140 in 1999. Let y be the average value of the automobile in the year x, where x = 0 represents 1994. Write a linear equation that models the value of the automobile in terms of the year x.


a. y = -1980x - 5760
b. y = -1980x + 4140
c. y = -1 / 1980x - 4140
d. y = -1980x + 14, 040

Mr. Shah decided to walk down the escalator of a tube station. He found that if he walks down 26 steps, he requires 30 seconds to reach the bottom. However, if he steps down 34 stairs he would only require 18 seconds to get to the bottom. If the time is measured from the moment the top step begins to descend to the time he steps off the last step at the bottom, find out the height of the stair way in steps?
