Cartesian Vector Question?
So this was a question on my recent vectors test:
Ship is sailing at a heading of 173 degrees at a speed of 35 knots. Wind is blowing from a bearing of 118 degrees at a speed of 16 knots. Determine the resultant speed.
We were asked to use cartesian vectors to solve. (Correct? answer should be 29 knots) Using this method, I get a different answer then if I did cosine law (46 knots).
Can someone show me what is going on with this, and which is truly the correct answer?
-> and yes I know it says FROM a bearing of 118
1 AnswerMathematics1 decade agoCreate a RegExp for me please?
I need to grab the value of this statement:
var transfer= 5.39;
Which would return 5.39. The 5.39 will be any number, greater then 100 is acceptable, and im not sure if it will always be 2 decimal places.
This is the only occurance of a transfer= in the searched text, so it shouldn't be too difficult to grab this number, I just am unable to make these statements aha. So what it should do is:
Value after "transfer=" and before ";" removing all whitespace.
Thanks!

3 AnswersProgramming & Design1 decade agoCreate XP disk?
A while back I ripped all of the files from my XP disk to my hard drive incase I lost my disk; and sure enough I did. So basically now I have all the files - the setup and a few folders with many folders in it. Now, I tried to burn to a CD, but when I start up my computer, it doesn't boot to the XP CD, just goes right to my hard drive, my BIOS is set to boot from CD first, so I have no idea why it's not working. Does anyone have any idea of how to fix it? Thanks.
