Question:I'm tutoring a child in 5th grade and want to make my lesson fun for her, but I can't seem to find some of the really cool graphs that were used when I was young.

Answers:These can be created in Excel or even in Open Office (If you do not have Microsoft Office with excel, you can get Open Office Suite for free at openoffice.org

Question:Hello, can someone tell me how to work out the answer to this question. http://img48.imageshack.us/img48/4369/51659233tn8.jpg I have done the first part, but the last part it is hard for me. Thank you =]

Answers:Hi. I think that the length of OM is just by calculating the magnitude of how far M is from O. In 2-dimensional space, it's just like finding the distance between two points, by taking the square root of the sum of co-ordinates, that is: sqrt (x^2 + y^2) In 3-dimensional space, we do this: sqrt (x^2 + y^2 + z^2) = sqrt (4.5 ^2 + 1.5 ^2 + 4.5 ^2) = sqrt (42.75) = 6.5, to 1 decimal place. Hope that helps!

Question:I have looked every where and can't find it...

Answers:First you have to make sure that you have a supply of good quality, three-dimensional paper. Ask at your local university bookstore. Just kidding. Since you can't REALLY graph in 3 dimensions, you have to make an "artist representation" of 3D. First graph it on the X/Y plane for your reference... then imagine turning it so that you are looking at from over the side. Draw in a Z axis that is perpindicular to BOTH the X and Y axis. Use a dotted line for the z axis so as not to confuse those looking at it. I am including a link to a quick drawing I made to give you an idea. http://www.WeDoTV.com/3d.jpg

Question:1.Graph the function . Find the range of the function given that the domain of the function is all real numbers x, except x /=/ 0. Draw a chart to show at least four ordered pairs that are on the graph. y = 2/x y equals 2 divided by x. now I want you to graph but I have no idea how to find the coordinates. Can someone help me or give me a few coordinates, I bearly understand this so if u explain as well, please don't be vague and brief. I repeat, dont! lolz

Answers:This is not Linear or an Inverse just y = f(x) = 2*(1/x) Four points : "plug in" a 1,2,3, and 4 everywhere you see an (x) and "simplify" the fractions f(1) = (2/1) = 2 f(2) = (2/2) =1 f(3) = (2/3) = 2/3 f(4) = (2/4) = 1/2 Your picture is here http://tinypic.com/r/fl8q5j/7 find 1 on x axis draw a vertical line "up" until it reaches the graph. then draw a horizontal line from the same point on the graph to the y axis. this is the y value (or f(1) value) point is read (x=1,y=2) find 2 on x axis draw a vertical line "up" until it reaches the graph. then draw a horizontal line from the same point on the graph to the y axis. this is the y value (or f(2) value) points are read (x=2,y=1) find 3 on x axis draw a vertical line "up" until it reaches the graph. then draw a horizontal line from the same point on the graph to the y axis. this is the y value (or f(3) value) points are read (x=3,y=2/3) find 4 on x axis draw a vertical line "up" until it reaches the graph. then draw a horizontal line from the same point on the graph to the y axis. this is the y value (or f(?) value) points are read (x=4,y=1/?)
