Apply Descartes' Rule of Signs to determine the possible numbers of positive roots of:
x^4 - x^3 - 3x^2 - x + 2 = 0
but not sure what i did is right....correct me if i did it wrong
f(x) = +x^4 - x^3 - 3x^2 - x + 2
f(-x) = -x^4 - (-x)^3 - 3(-x)^2 - (-x) + 2
= -x^4 + x^3 + 3x^2 + x + 2

89 * (.47 - .29) = 1.14x
89 * 0.18 = 1.14x
16.02 = 1.14x
x = 14.05263158
x = 14.05 ounces

#13 Re: Help Me ! » solve help please tryed many ways..all came out wrong » 2006-12-22 05:18:15
that wht i had also......
but its wrong
why
if u put in 11...
6 * 11 =66
66 - 2 = 64
sqrt64 = 8
then ohhhhhhhhhhhhhhhhhhhhh myyyyyy god
lol u know hwt i did
i did teh same thing that you all did but at teh end i said sqr8 - sqrt9 lol
ohhhhh my god
thanks guys

Consider the equation, 4x^2 + 9y^2 - 64 + 72y + 364 = 0. Tell what conic section this represents and sketch its graph.
This is what I did:
(4x^2 - 64x. . ..) + (9y^2 + 72. . . .) = -364
4(x^2 - 16x. . ..) + 9(y^2 + 8y. . . .) = -364
4(x^2 - 16x + 1) + 9(y^2 + 8y + 8 ) = -364 + __
4(x^2 - 16x + 1) + 9(y^2 + 8y + 8 ) = -364 + 4(1) + 9(8)
4(x^2 - 16x + 1) + 9(y^2 + 8y + 8 ) = -364 + 4 + 72
4(x - 1)^2 + 9(y + 0.9)^2 = -288
[4(x - 1)^2] / -288 + [9(y + 0.9)^2] / -288 = -288 / -288
or
(x - 1)^2 / (sqrt(-72))^2 + (y + 0.9)^2 / ((sqrt(-32)) = 1
Is this correct?

b(1c + c)+ 2ac 1c + c
--------------- ---------------------
1c + c b(1c + c) + 2ac
Then

and this is my answer

in a group of sinngle mothers, 14% were on welfare while the others were employed . if 4300 were employed, how mmany mothers in this group were on welfare?
i did this..but now i think what i did isn't right. what are your thoughts on what i did :
14/100 = x/4300
100x = 60200
x = 602

#23 Re: Help Me ! » Identity » 2006-12-06 04:59:36
neva mind guys i got it
sin(A + B) = sinA cosB + cos A + B
sin(A + A) = sinA cosA + cosA sinA
sin 2A = 2 sinA cosA

Develop the identity for sin 2A using the identity sin(A + B)
http://www.mathwords.com/t/trig_identities.htm
use this formula
sin 2x = 2sinx cos x
or use this formula
sin(x+y) = sin x cos y + cos x + sin y
#25 Re: Help Me ! » Triangle » 2006-12-05 06:04:14
ok this is what i did:
c^2 = a^2 + b^2 - 2ab cos P
A^ = 11^2 + 15^2 - 2(11)(15)cos 65dg
A^2 = 121 + 225 - 139.4640264
A^2 = 346 - 139.4640264
A^2 = 206.5359736
A = 14.37135949
A = 14.4
NEXT
14.4/sin65 = 15/sinB
sinB = 15sin65/14.4
SinB = 0.945952038
NEXT
14.4/sin65 = 11/sinC
sinC = 11sin65/14.4
sinC = 0.012106812
CORRECT
