I'm not sure of which language u are using but I'll give you an alogorithm(that is logic in simple lang) hopefully u can convert it to ur need.\n\n1: U r on the right track. Taking 55 as speed limit\n\nFunction Radar(takes userinput)\n{\n   if(userinput< 55)\n     print "under limit"\n   else if(userinput=55)\n     print "at limit"\n   else if(userinput>55)\n     print "over limit"\n}\n\ndont user AND ... it is wrong in the logic.\n\n\n2:\n\nFunction Tax(grosspay=User's Input)\n{\n   if(grosspay<=240)\n     tax=0\n   else if(grosspay>240 and grosspay<=480)\n     tax=grosspay * 0.15\n   else if(grosspay>480)\n     tax=grosspay * 0.28\n\n   print tax\n\n}\n\nHopefully u'll be able to convert it to ur required language\n}

Well, you have to do one for each case.\n3 pos. and 2 neg. would leave 0 imaginary\n3 pos. and 0 neg. would leave 2 imaginary.\n1 pos. and 2 neg. -- 2 imaginary\n1 pos. and 0 neg. -- 4 imaginary\nAll the possible case have been covered.

The first one is (-5, 3). I don't remember how to do the others.

T1=m1*a, no matter are there m2 & m3 or not.\nT2=(m1+m2)*a, no matter whether m1 & m2 are connected with a string or are in one lump, the presence of m3 being unimportant too.

Problem 1: in 2005, t=2005-1998=7\nin 2008, t=2008-1998=10\namt property appreciates by between 2005 and 2008\n= f(10) -f(7)\n=75,000(1.06^10) - 75,000(1.06^7)\nfind the answer by typing the above into a calculator\n\nI don't really understand problem 2. What are you trying to find?\n\nI'm thinking it could be either P or r:\nTo find P: A=Pe^rt\ne^rt=A/P\nIn(e^rt)=In(A/P)\nrt = In(A/P)\nr = [In(A/P)]/t\n\nTo find P:\nP = A / [e^rt]\n\nI hope these were helpful.

Directions how to do this can be found in the text book.\n\nDo your own homework!

Its tricky work, i need digrams to explain to you so your better just following this link, I think it will help you out.

By the def\n\nlim f(x + h ) - f(x)\n              /h\nPlug in (x+h) into f\nlim (x+h)^2 + 5(x +h) - (x^2 + 5x)\n                        /h\nFoil\nlim x^2 + 2xh + h^2 + 5x + 5h - x^2 - 5x\n                          /h\n\nCancel like terms\nlim 2xh + h^2 + 5h\n           /h\n\n\nReduce everything by h\nlim 2x + h + 5\n\nTake the limit and\nPlug in 0 for h\n2x + 5

(3/51) * (48/50 * 3/49) * (44/48 * 3/47) * 40/46 * 7!\n\nNote: As I read it, #2-#4 exclude the possibility of #1.  If you think #1 is a special case of the others, then add the value of #1 to the other three.  Likewise, as I read it, #5 excludes #2.
