k guys im kinda doing my second portfolio right now n im kinda stuck on one part of the question
height 1.7 2.0 2.9 4.1 5.6 6.3 7.0 8.0 10.0 13.9
number of drops 42.0 21.0 10.3 6.8 5.1 4.8 4.4 4.1 3.7 3.2
they given us information on crows dropping nut.. with the height and the number of drops.i managed to plot this graph n i get an Hyperbole graph. the question asks
what type of function models the behavior of the graph? explain why you chose this function.create an equation (a model)that fits the graph.
i dont get how to get the equation they asking for. please could someone help me urgently..or explain to me.thanx
What does 'cows dropping nut mean?'. Only then will I help you.
yea i went thru it and it is a decreasing exponential graphso wat u mean by this equation Ae^kx + divide by -Be^mx
aite so i jus concentrate on the y = Ae^kx?
Just concentrate on y = Ae^kx.
oh ok thanks a lot... will see how i progress. gotta give it in on Wednesday.will let you know about any other problems..thank you so much
By "Define all Variables", it should mean simply stating the variables and factors that can affect the dropping of the nut. If you have done physics, chemistry, bio or whatever, reports, it will be similar to "Control of Variables".
This includes stating the dependent and independent variables and what you are assuming, eg. No wind when the nut is dropped.
I'm still doing this so yeah xD Progressive learning.
I'm doing the same problem and we were told to do it on the TI-84 calc, but I can't find any stat things that fit the graph. In y = Ae^kx, is that on the calc? And is k just b?
Hey I'm doing the same portfolio however im having some problems of my own. does anyone know how were supposed to explain the question: what type of function models the behaviour of the graph? Explain why you chose this function. Create an equation (a model) that fits this graph. ? I have figured out what type of graph it could be based on my knowledge in math but im not sure how were supposed to explain it especially since it was all trial and error on my GDC that gave me the equation. I just kept plugging in numbers and translationing the graph a bit and streching it some. But i dont know how were supposed to explain it. I dont have to show graphs for every step i did do i? please if anyone can help that would be awesome.
im so confused..what would the equation b?
You really need to use the STAT function on your GDC, its really easy to do
Press STAT and then edit on the first menu(edit)
read about corellation coefficients( r and rsquared values)
turn on diagnostic on your calculator 2nd function, catalo, scroll, enter on diagnostic on, enter again
Use STAT again but this time go to Tests, it gives you a variety of functions
if you read about corellation coefficiecient you'll know which one to pick
Feel free to rep me please!!
oh no i understood that part. i was just wondering how to derive the equation..
