Mathematics - 17 September 2007

Hi. I am currently taking my GED and I have major problems with math, particularly with basic word problems and algebra word problems. I do not understand how to solve them. I would greatly appreciate any advise on how to solve these word problems. Thanks.

I have proved 4 1 n got 1/3 for both

now it wants me to prove for k

which i got n's as k's

its when k+1 that i just cant seem to get and answer at all and the examples i have got to help me with are all basics where the r's are straights powers ie ^2 not fractions as I have and I am really confussed

Please help!!!
Identify the parent function for g(x)=(x+3)^3 and describe what transformation of the parent function it represents.

I know the parent function is the cubic function, f(x)=x^3 but I need help with the type of translation.

Thanks everyone for your help!

identify the plane curve given by the vector-valued function: r(t) = 3t^(2)i + (1 - t)j

is it a parabola, a hyperbola, a line, a circle ... or none of those???

y' = sqrt(x+y+1)

We've normally been substituting vx for y, and vdx + xdv for dy, but i'm so lost from the start :(

THANK YOU VERY VERY MUCH IN ADVANCE!!!

a. Consider f(x), g(x) E Z(subscript 7)[x], where f(x)=x^7, g(x)=x
Prove that f(c)=g(c) for all c E Z(subscript 7)?

b. Now let f(x), g(x) E Z(subscript 7)[x], where f(x) does not equal g(x) and deg f <7, deg g<7.
Prove that there exists c E Z(subscript 7) such that f(c) does not equal g(c)?

Help would be much appreciated!

Can someone please determine q(x) and r(x) as described by the division algorithm such that f(x)=g(x)q(x) + r(x) so that i can check my answers for the following:

a. f(x)= x^6+3x^5+4x^2-3x+2 and g(x)= x^2+2x-3

and

b. f(x0=x^6+3x^5+4x^2-3x+2 and g(x)= 3x^2+2x-3

Cheers

Hey! My name is Jessica and i have a project due tomarrow. I really don't know what I am doing so if someone could help me out, that would be great. Also, if I don't make an A or B on this project I will not make an passing grade and I will be kicked the the pom pom squard at my high school(Whitehaven High yea yea). So please, please, help a sista out.

If you really don't understand what I am asking then here is an example: Pizza is in the shape of a triangle and or circle. The hands on a watch are angles.... This is what I need...Please!!! And Thank You!!

The problem asks you to use the Intermediate Value Theorem to prove that a polynomial f(x)=1+2x+9x^2...3^101x^101 has a real zero.

How would you do this, especially with such a large number? Thanks for any help!

okay, I'm not sure how to say it but Z5 is Z(mod 5) I think.
there are four parts to this question and if I know the first two or three I think I might be able to get this so I appreciate the help.

A) In Z5 compute (a + b)^5.
B)In Z3 compute (a + b) ^3.
C) In Z2 compute (a + b) ^2.
D) Based on the results of parts (a) - (c), what do you think (a + b)^7 is equal to in Z7?
Thanks!
