it seems you are either missing some info here or im a bit more rusty on geometry than i thought, how exactly did you find C?
anonymous
  • anonymous
I came up with t^2=A(4+3t)^2+B(4+3t)+C
anonymous
  • anonymous
but i'm still kind of confused as to how I even got it ha

  • anonymous
it's the correct problem i checked
anonymous
  • anonymous
yeah, you have 3 variables there and no way to eliminate any of them, so unless your proff gave you some format to put it into and then from that you know the points your trying to find?
anonymous
  • anonymous
i mean the way to eliminate them is to use the t value and then deal with that bottom equation
anonymous
  • anonymous
so lik eeither put everything in terms of x or y
anonymous
  • anonymous
right but you can only ever solve the variables in terms of the other variables, meaning you can find A as a function of B and C, B(A,C) and C(A,B)
anonymous
  • anonymous
yes i know that's why i need to find a way out by plugging in constants on both sides of the equation that make A or B go to zero in order to solve for the variables
anonymous
  • anonymous
ahh, right. and then you just do the same thing to find A and B i think, set the ones your not finding to 0
anonymous
  • anonymous
see i don't know how to do the rest i'm really cracked out and can't thinka nymore ha
anonymous
  • anonymous
honestly you should confinr that with someone else too though, its been a while since iv done a problem like this
anonymous
  • anonymous
if your finding A you just set B and C to 0 because they are intercepts, right?
anonymous
  • anonymous
well i'll know if it's right because i have to type my answers into a computer system that will tell me if it's correct or not

here we go: http://www.personal.kent.edu/~rmuhamma/Algorithms/MyAlgorithms/parabola.htm
anonymous
  • anonymous
so you have a polynomial function of the 2nd degree which is a quadradic
anonymous
  • anonymous
ok
anonymous
  • anonymous
question where do u go to school?
anonymous
  • anonymous
this is a trickey little bastard, you have to change the form of the original equation. see If b = 0, the quadratic function has the form f(x) = ax2 + c. so what i think you have to do, is noting those derived equations and plugging in 0 to the other variables you get some new equations which then allow you to solve for the others by plugging them into eachother. lemme keep reading

ughhh it sucks!! i haven't slept in two days fml
anonymous
  • anonymous
lol its been too long, i dont understand what that website is saying...
anonymous
  • anonymous

anonymous
  • anonymous
nah im just a student
anonymous
  • anonymous

i go to u of r
anonymous
  • anonymous
no way hahaha thats crazy. i was about to say dont even lie to me that you go to rit, your sn has "girl" in it
anonymous

anonymous
  • anonymous
bosston, i lived there this summer ha, well i lived in watertown
anonymous
  • anonymous
literallrally everyone from u of r is from boston
anonymous
  • anonymous
i say boston its really the southern NH border but i'v driven through watertown more than once. and yeah it seems like that here too, i know tons of people from the boston area
anonymous
  • anonymous
im still in awe that at 2am out of 23 online people i found someone thats currently within a 10 mile radius of me
anonymous
  • anonymous
i am too, it's just too weird
anonymous
  • anonymous
what do you major in ?
anonymous
  • anonymous
computer engineering technology, you?
anonymous
  • anonymous
ha sounds intense, i'm doing business econ and psych
anonymous
  • anonymous
haha im concentrating in psych, too weird
anonymous
  • anonymous
haha oh the weird realms of the internet
anonymous
  • anonymous
its got to be less coincidental than were making it out to be. were in a pretty tech-savvy part of the english speaking world. but still thats the whole northern east coast...
anonymous
  • anonymous
how did you find this site?
anonymous
  • anonymous
haha idk i was just wearching for help things and it came up
anonymous
  • anonymous
why do you help random people with math?
anonymous
  • anonymous
honestly i dont really know
anonymous
  • anonymous
i kinda stumbled here like 2 days ago and got a kick out of helping people out with their math, most of the stuff on here is low level calc or easier so its not so bad
anonymous
  • anonymous
guess i got sick of facebook and this was another way to procrastinate?
anonymous
  • anonymous
i guess that's not a bad way to procrastinate, bettering the world's math skills
anonymous
  • anonymous
haha, yeah doing other people's homework is fun but doing my own is agonizing, go figure
anonymous
  • anonymous
ha
anonymous
  • anonymous
what class is your parabola thinger from? i dont remember having to do this stuff
anonymous
  • anonymous
third semester of calc
anonymous
  • anonymous
shows how much i learned in calc...
anonymous
  • anonymous
but it's something i learned a long time ago, i just don't remember it
anonymous
  • anonymous
don't worry though, i have the rochester minions working on it
anonymous
  • anonymous
the rochester minions eigh?
anonymous
  • anonymous
yes
anonymous
  • anonymous
you should prolly let me know how to go about contacting these minions. could be helpful for diff eq
anonymous
  • anonymous
haha, you literally just walk around u of r campus, they're around, sometimes you have to look in the stacks or the depths of the librar but there's always a guarantee you'll find one
anonymous
  • anonymous
haha, even at 2 am. that seems sketchy, especially the library part, whats a library?
anonymous
  • anonymous
the minions are having trouble with it too, darn
anonymous
  • anonymous
tell your professor that its impossible. ill see if my roomate knows how to do it
anonymous
  • anonymous
ok it's just it's due tomorrow morning at 6am ick
anonymous
  • anonymous
haha people keep looking at this question and then leaving
anonymous
  • anonymous
theres 3 rit kids in here working on your silly parabola
anonymous
  • anonymous
you said you have infinite number of trys?
anonymous
  • anonymous
\[y=4+3\sqrt{x}\]
anonymous
  • anonymous
give that a go
anonymous
  • anonymous
i'll try it
anonymous
  • anonymous
idk how long this website will wokrk though, its slowing my comp down a lot
anonymous
  • anonymous
i got A it's 1/9, idk if that will help find B
anonymous
  • anonymous
lol i have no idea how you got that or what it means. anyways im going to go sleep or eat or something, facebook me (Tim Heebs) you should come to some parties and bring friends. god knows RIT needs help with the ratio at parties haha
anonymous
  • anonymous
haha yea, your name already showed up when i was worried about the problem, and yea us girls here sometimes want to go to some RIT parties, that would be cool
anonymous
  • anonymous
sounds good, ttyl then. good luck with your calc
