Answer:

$\dfrac{4 \cdot x^4 - 5\cdot x^3 + 2 \cdot x^2 - x + 5}{x^2 + x + 1} = 2 \cdot x^2 - 9 \cdot x + 7 \ Remainder \ (x - 2)$

Step-by-step explanation:

Part I

The problem can be expressed as follows;

The dividend is 4·x⁴ - 5·x³ + 2·x² - x + 5

The divisor is x² + x + 1

$\dfrac{4 \cdot x^4 - 5\cdot x^3 + 2 \cdot x^2 - x + 5}{x^2 + x + 1}$

Part II

The number of times x² goes into the larest term, 4·x⁴ = 4·x² times

2·x² - 9·x + 7

$\dfrac{4 \cdot x^4 - 5\cdot x^3 + 2 \cdot x^2 - x + 5}{x^2 + x + 1}$

4·x⁴ + 4·x³ + 4·x²

-9·x³ - 2·x² - x + 5

-9·x³ - 9·x² - 9·x

7·x² + 8·x + 5

7·x² + 7·x + 7

x - 2

Therefore, we have;

$\dfrac{4 \cdot x^4 - 5\cdot x^3 + 2 \cdot x^2 - x + 5}{x^2 + x + 1} = 2 \cdot x^2 - 9 \cdot x + 7 \ Remainder \ (x - 2)$

zepelin [54]

Answer:

A)equation=A=318-27.9·T

b)A=318-27.9·6= A=150.6 students per counselor

C)200=318-27.9·T= 4.2 Years

Step-by-step explanation:

A) A=318 students per guidance counselor, that number decreases

T= time that passed from 2009

Then the equation would be like==

A(students per counselour)= 318(Number in 2009)-27.9(Less every year)·T

b)Resolve thje equation changing T by 6---->Thats because 2015-2009=6

A=318-27.9·6= 150.6 students per counselor.

C) Resolve the equation changing A by 200

200=318-27.9·T= (200-318)÷(-27.9)== 4.2 years(T)
