I just used a program, like what the administrator was talking about, that I made myself
ganesh I just used a calculater to figure it out so it is accurate
89376 and 09376???
Umm just to let you konw this problem was already posted a few days ago under the name of "I have a conundrum", the answer is there.
What I meant is 4 and 6\7 as a mixed fraction simplyfied from the improper fraction of 34\7 where the 34 is divided by 7, 4 equal times with 6\7 left over, so it 4 and 6\7
for the first part to find the mean just add all the numbers together like this:
8 + 7 + 7 + 5 + 3 + 2 + 2 = 34 then you divide that answer by the amount of terms or the amount of numbers, which is 7. so then it would look like this: 34/7 which simplifys down to 4 6/7.
For the second problem think of f(x) to be just another way to put down a variable, "y"
so f(x) would just be y. so then for f (4) = 0 means that some function gives out the value of 0 when y = 4 and the second part f (6) = 6 means that the same function gives out a 6 when y = 6. so then you know that the function has to give out a 0 when y = 4, so then you can just put in 4 for all the x's untill one of them gives out the value of 0, in this case it is 3x - 12 where
3*4 - 12, 12 - 12, 0 , so that equation works for the value of 4. then you check it with the other part where y = 6 so 3*6 - 12, 18 - 12, which turns out a 6. so the equations works for both the values so it is the right answer.
These are all good ideas and yes I do agree with you mathsyperson. The reason im interested in this topic is just for my own knowledge and curiosity. Right now I am reading something called flatland to try to help me understand more about other dimensions, When im done I will tell about anything interesting I learned. Oh and sorry if I started this in the wrong forum my mistake.
Im looking for any ideas on how to explain the fourth dimesion to someone in a non mathmatical way
Yes it is a 3 divided by a 2. Now after following some of their advice I combined both terms to make one term which is: (3x - 3) + (sqrt(2x^2 - 7x - 4)) All divided by 2. But I can't get any further at the moment
well anyways back to my original question, I got some help from a friend and they said to start by making the (3/2)(x-1) into one term, and then multiply the sqrt by something that will allow you to combine it with the expanded fraction, then go from there. And they said that the final solution will end up with a square root inside of a square root, and that there wasnt a way that they knew to get around it.
Thanks, I was having some mental issues at the time...
factor completely: 128x^6 - 2y^6
I can expand it to: 2(8x^3 + y^3)(8x^3 - y^3)
I know it can be expanded more but how would that go?
So does anyone have any idea on how to do this problem?
Im not having any better luck with this problem
Find the square root of (3/2)(x-1) + (sqrt(2x^2 - 7x - 4))
its not equal to anything so its all about manipulation, thats about all I can help lol.
thanks a bunch I hate logarithm stuff
The special property is i think just the property for logarithms with the same base:
where for positive mumbers b,x, and y where b != 1, log(b/x) = log(b/y) if and only if x = y.
I think...
and so x = -5, 10 I got that to
now I just need help on the second problem
I have another problem too, a logarithm problem
solve 2^(x +1) = 7^(x + 2)
wait never mind I got it
solve, sqrt(11 - x) - sqrt(x + 6) = 3
Preform the indicated operations. Simplify the answer in simplest form.
1 + _____1______
1 + ____1____
1 - x
so far ive gotten here 1 + ______1_______
1 - x + 1
_____________
1 - x
if x = (c - ab) / (a - b) , find the value of the expression a(x + b) in simplified form
So far I have gotten this far
substitute : a ( (c - ab) / (a - b) + b )
simplify: ( a(c - ab) / a - b ) + ( ab/ 1 )
( a(c - ab) + ab(a - b) ) / (a - b)
( ca - a^2(b) + a^2(b) - ab^2 ) / (a - b)
( ca - ab^2 ) / (a - b)
Is this all I could simplify it, or am I missing something?
I know, but i can handle that. It was just my approach that was getting me. I was trying to go at it in a more complicated way
Wow it makes alot more sense putting it that way, I was tying to aproach it from some other way, which turned out horrible.Thanks for the help I understand it now
