Best ResponseYou've already chosen the best response.1the table is linear because the equation for it is \(y=2x\)

Best ResponseYou've already chosen the best response.1if you have the same ordered pairs as from the table

Best ResponseYou've already chosen the best response.1so then yes the table matches the graph

Best ResponseYou've already chosen the best response.1and to find the 10th, just look at the y when x = 10

Best ResponseYou've already chosen the best response.0so wait this would be linear or exponential? I'm all confused again :/

Best ResponseYou've already chosen the best response.0okay wait the table when graphed is linear and then the equation I get using exponential regression, has to be  exponential?

anonymous

Best ResponseYou've already chosen the best response.0Okay I found a website that does exponential regression using a table. & I think I have to do y=ab^x my numbers are a= 2.550657097 and b=1.259112119 are these right?

Best ResponseYou've already chosen the best response.0you don't need to do exponential regression for this because it's linear. The line of best fit is exactly \[y=2x\]

anonymous

Best ResponseYou've already chosen the best response.0I think I just thought it was expo because that's what the whole lessons about but yeah I mean it looks linear, but I still have to use expo regression (or constant ratio) to get an equation for this table and my rate of changes.

Best ResponseYou've already chosen the best response.0oh wait did you fill out that table or did they give it to you?

anonymous

Best ResponseYou've already chosen the best response.0no I had to fill it in.

Best ResponseYou've already chosen the best response.0they gave me the first two and i did the rest

Best ResponseYou've already chosen the best response.0ok so each round DOUBLES # of rounds  ppl receiving forward 1 2 2 4 3 8 4 16

anonymous

Best ResponseYou've already chosen the best response.0That would make it exponential

Best ResponseYou've already chosen the best response.0oh dang really? I knew my table was wrong, but I didn't know exactly how.

anonymous

Best ResponseYou've already chosen the best response.0okay well at least that is cleared up.

Best ResponseYou've already chosen the best response.0i'm going to redo this graph in google to see how it looks

anonymous

Best ResponseYou've already chosen the best response.0ok. I think it should go smoothly from there

anonymous

Best ResponseYou've already chosen the best response.0okay yeah it looks exponential now

anonymous

Best ResponseYou've already chosen the best response.0those rates of changes aren't going to be correct because the points changed

anonymous

Best ResponseYou've already chosen the best response.0oh yeah sorry sorry I realized that as I posted them.

Best ResponseYou've already chosen the best response.0We did exponential earlier. Once you have the graph you can add the trendline

anonymous

Best ResponseYou've already chosen the best response.0How did we get exponential? I remember just the equation being on the side there.

anonymous

Best ResponseYou've already chosen the best response.0yeah you have to add the equation from the advanced options where you go to edit the chart

anonymous

Best ResponseYou've already chosen the best response.0something like advanced edit I think

anonymous

Best ResponseYou've already chosen the best response.0okay so I have y=1e^(0.693x) how do I graph this over my original graph?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0I think it graphs automatically

anonymous

Best ResponseYou've already chosen the best response.0or I guess the line is just the same because I'm not seeing a new line just the one I had

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0yeah they'll be very close together for this one because you made up the points to match the function. y = e^(0.693x) is basically the same as y = 2^x

anonymous

Best ResponseYou've already chosen the best response.0okay yeah when I did advanced edit and all that stuff, the dot graph I had just changed to the plots being connected with a line, so I guess that they overlay eachother?

anonymous

Best ResponseYou've already chosen the best response.0yeah that sounds right

anonymous

Best ResponseYou've already chosen the best response.0how do I figure that out? Something with the 10th round?

anonymous

Best ResponseYou've already chosen the best response.0my connection is so bad rn I don't know if I'm seeing replies

anonymous

Best ResponseYou've already chosen the best response.0your equation is y = 2^x 50000 = 2^x Solve for x
