umm when x=0 y is .17, and when x=1 y is .1989 but I fail to see how that explains what A and B represents in context (stock markets and investments atleast I think) These numbers pose no solution to me at all. Could you give me some more help?

Umm its tough to see so I'll write the question too... The standard deviation of the annual growth rates of a mutual fund is an indicator of how volitile or risky the fund is. Determine the upper and lower limits of the annual growth rate for each fund, such that there is a 0.75 probability...

Hi I'm doing some homework and I have the main question answered but this added one is hurting me. Let me give you the entirity of it... - For each company ABC and XYZ write an exponetial regression equation in the form of a X b^x (Thats A times B to the x), where x = number of yeats and why =...

okay... I kind of get it... I did this... log(y/x) = 2a + 2z so that's logx = (2(a+z))/y I'm still stuck

uhh not really, you could elaborate on that idea though? Would it be like... logx = xlog then xlog^2(a+z) Sorry I'm really confused/

I've been looking through my textbook for a question even remotly similar and no luck, if you could get me started witht this question I'd love to do it and then I'll write what I got and write it here. If y=x^2(a+z) determine an expression equal to log x. (Hint: you will need to take the...

wow thanks jimmy so i go... f=ma... 6.67x10^-11/10kg... then times that by 2... and I get... 1.334.10^-11. and then i use that as my acceleration... so a=v/t somehow i got 7.488 x10^-11 as my final answer does this look right?

so would i do... fg=Gm1m2/r^2 fg=6.67x10^-11 then take that... and do f=ma? so 6.67x10^-11/10kg, or would I do 20kg, or am I way off track?

I was given a few questions from my teacher to practice for my final exam which is coming up soon, here are the ones I am having troubles with, if anyone can show me how to do em that would be great. 1. Astronauts release two 10.0 kg objects from a space shuttle and place them 10.0m apart, at...

I don't understand that at all... I would have thought I'd try and figure out what m was = to then, maybe do that... because from what I know I don't think I can figure out the net gravititional force from just what I was given... A little more help? heh

I'm having troubles with one of my homework questions, and I was wondering if someone could help me with it. okay here it is... Q: Two masses, object A and object B are located 2m apart from each other, the mass of object a is m and the mass of object b is 4m. Showing your...

just to double check the first question is 43.2 J, and the second 33 m/s? please confirm or if if I'm wrong tell me.

wow thanks a lot, I'm doing the two questions as we speak and having no problems at all. :smile:

I have been absent from my physics class for the past week due to an illness, and now am having troubles with some of my workbook questions. There are two in particular which my teacher had told me to know how to do as they would be on my test in the next few days. the ones he wrote out...
