Question 175312: I need help really bad..What is a Remainder Theorem?
Ihave been working on these problems for over two hours help
1. Use the Remainder Theorem to find the reaminder when f(x) is divided by g(x)
1. f(x)=x^4+8x^3+12x^2;g(x)=x+1
2. f(x)=5x^6-3x^3+8;g(x)=x+1
Someone please help m,e on these.....It is important....Thank you

Question 175618: Could you please help me! Iam not sure if I done it right with this problem. A cellular phone company offers a contract for which the cost C, in dollars of t mintues of telephoning is given by C=0.25 (t-500) + 70.85, where it is assumed that + great than 500 mintues. What time will keep cost between $122.95 and $145.70? For the cost to be between $112.95 and $145.70, the telephoning time must be between __ mintues and __mintues.

Question 175772: Well I am pretty sure this is the topic we are doing. The one i selected above.
Well anyways, this is the problem I have just been stuck on for EVER. it has 3 part, A, B, and C. and you cant get B or C if you dont get A. and ive been stuck on A. but even if i get past A, Im stil not quite sure if i know what to do with B and C.
Let p(x)=x(x-3)^2(x+1)
A) Sketch this graph of p(x). Label all intercepts. <-- I'm not even sure i know how to graph this at all. could you walk me through it?
b)Find another polynomial funtcion, q(x), that has the same zeroes as p(x) and goes throught the point (-1,16). <--- once i get the first graph I'm not sure How i would MAKE it go through (-1,16), How would i go upon doing that?
c) Explain how to determine the end behavior of a polynomial function. <--- what does it mean by determine if we already solved it above?

3. In 1933, the life expectancy of males in a certain country was 62.3 years. In 1998, it was 65.9 years let E represent the life expectancy in year t and let t represent the number of years since 1993.
The linear function E (t) that fits the data is E (t) =__t +__
Round to the nearest tenth
Use the function to predict the life expectancy of males in 2005 E (12) =
(Round to the nearest tenth)
