P(1/2) = 2(1/2)^3 - 9(1/2) - 10 P(1/2) = -57/4 P(0) = -10
anonymous
  • anonymous
is that good enough?
anonymous
  • anonymous
2(1/2)^3=1/4 9(1/2)=9/2 1/4-9/2-10 this is where i am stuck what do i do to get the correct answer
anonymous
  • anonymous
okay so \[\frac{1}{4}-\frac{18}{4}- \frac{40}{4}= -\frac{1-18-40}{4} = \frac{57}{4}\]

How do you do fractions chiarocuro?
anonymous
  • anonymous
what do you mean?
anonymous
  • anonymous
to add and subtract, you have to find a common denominator (preferably a LEAST common denominator) and change the fraction accordingly. Then add and subtract. to multiply, you just multiply numerator by numerator and denominator by denominator to divide, flip (the reciprocal) the fraction right after the dividing sign and then multiply
anonymous
  • anonymous
lol you're silly. I mean how make fractions come out in equations? like you did there.
anonymous
  • anonymous
lololols oops sorry in the equation editor type \frac{numer}{deno} replacing numer and deno for numbers cheers
anonymous
  • anonymous
ok thanks. So is equations like latex? That's what I use in latex to do fractions.
anonymous
  • anonymous
I'm never touched latex, so i couldn't tell you :x

i need fractions for dummies p(1/4)=4(1/4)^3+9(1/4)-3 please explain this problem step by step i can not do fractions even the basic it nvr made sense to me
anonymous
  • anonymous
\[4*\frac{1}{4}*\frac{1}{4}*\frac{1}{4} + \frac{9}{4} - 3\] \[\frac{1}{4}*\frac{1}{4} + \frac{9}{4} - 3\] \[\frac{1 * 1}{4 * 4} + \frac{9}{4} - 3\] \[\frac{1}{16} + \frac{9}{4} - 3\] \[\frac{1}{16} + \frac{9 * 4}{4 * 4} - 3\] \[\frac{1}{16} +\frac{36}{16} - 3\] \[\frac{37}{16} - \frac{3}{1}\] \[\frac{37}{16} - \frac{3 * 16}{1 * 16}\] \[\frac{37}{16} - \frac{48}{16}\] \[\frac{-11}{16}\] sorry that took so long...but that was a lot of equations :P

mathlab says thats wrong its -83/16
anonymous
  • anonymous
nope i used my calculator to check, i'm right. you can use matlab, but you don't know how to do fractions? please don't take offense! i'm just curious
anonymous
  • anonymous
we do our homework in mathlab and i know how to do fractions just forgot exactly how its been so long
anonymous
  • anonymous
copy this into matlab 4(1/4)^3+9(1/4)-3 ^-- thats the line you gave me it should give you -.6875, which is -11/16
anonymous
  • anonymous
we might be talking about different things then nvm i'm talking about matlab you're talking about mathlab so nvm :P but i'm sure i'm right, as long as you gave me the right question but since you're trying to understand how to do fraction, just see if you can follow along the steps. because you want to know how to do it, not the answer
anonymous
  • anonymous
right
anonymous
  • anonymous
its a polynomial function given values of the variables p(-4) & p(1/4) P(r)=4rᶟ-9r-3 P(-4) and P(1/4)
anonymous
  • anonymous
?

whoa...you still on this question? did you sleep?!?! O_O
