1296 = 6^4\n\nThe first digit can be chosen in 6 ways. the second digit can be chosen in 6 ways. similarly for the third and fourth digits. that makes it 6 * 6 * 6 * 6 = 1296.

Well, number one would be:\n\nCost=0.03X^2 +1.15X + 1.37\n\n(An approximation)

0, unless this is another one of those trick questions.

If it were plus, instead of times, the answer would be 1.\nAs it is, I don't recognize it.  Perhaps my math is a bit rusty...

if \na=(v-u)/t\nthen\na*t=v-u\nthen\nt=(v-u)/a\nor\nt=(15-0)/0.75 \n\nSo as the previous poster says the answer really is 20

1\n\njust do a little bit of trial you will see that the smaller number you use it nears 1.

[ (50000 x 2.4)+(25000 x .8) ] / (50000+250000)=1.8\n\nThe remainder of the info in the problem is not necessary.

half it then times it by 2! that will give u the answer

Use the binomial.  I've already shown you how in a previous question.  And you already know that you need to use it.

Let x be one number\nother number=100+x\nproduct\n=x[100+x]\n=100x+x^2\ndifferentiating\nf'x=100+2x\nthis is a minimum \nwe put this=0\n100+2x=0\nx=-50\nthe numbers are\n50,-50

Just one if its long enough!! thx.

At most shouldn't it take only 13 minutes?  If 1 & 2 cross together, then they will take 3 minutes, and if 3 & 4 cross together, they will need 10 minutes.  10 + 3 = 13.\n\nMaybe I don't really understand the question??

120\nx.25\n------\n3000\n\n~~move decemal point over two places so the answer is 30.00 or can be written 30~~

2x+3<6x-1\n2x-6x<-1-3 \n-4x<-4\nx>1

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

its simple ... 80*70*60 ... 10*0 = 0 !!\n\nright isnt it ??? :D
