Can anyone give me the solution (code ) for this problem.:
In a circuit , if the resistor R4 changes from 0Ω to 40Ω in 0.2Ω steps and Vs changes from 4v to 24V in 0.1V steps, write a program to plot 3D graphics of the voltage on R2 against both the resistance of R4 and the voltage Vs using Matlab.(Here R1,R2,R3 are series and R4,R5 ,R6 are parallel to them)

Thanks

Bill and Wilma start from the same point and travel along straight roads that are at right angles to each other. Wilma travels 3 miles an hour faster than Bill. At the end of the 2 hours, they are 30 miles apart. How fast is each traveling?

I know this represents a right triangle but I can't figure out how to set up the equation and solve it. Can someone please show me step by step on how to solve this? Thanks.

As the fraction-stein monster attacks. Ms.Mathlete spots this multiplication problem on an poerating table: 4/7 x 28/1. Follow these directions to figure out which channel number they should hit: A) Write 28 as a fraction with 1 as its denomnator. B) Multiply numerator times numerator and denominator times denominator. C) Divide numerator and denominator by their greatest common factor. D) Your final answer is the product in its simplest form. If its denominator is one, rewrite the numerator as a whole number.

OK, I have a UTI (Urinary Tract Infection) and am supposed to be drinking LARGE amounts of water throughout the day. Some women advise to drink enough that you're peeing every 15-20 minutes. But I just heard about this horrible story: http://www.nbc11.com/news/10746017/detail.html?rss=bay&psp=news Scary stuff! Do you think she ran into problems because she was trying NOT to urinate?

Anyway, right now I'm chugging it out of these 1.5-liter bottles... How much can I drink safely?
