ANSWER

$y = 3 \cos(2x + 2) + 2$

or
$y= -3\cos(2x + 2) + 2$

Any of these two are correct

EXPLANATION

The general cosine function is

$y = a \cos(bx + c) + d$

where

$|a|=3$

$a=\pm3$

is the amplitude.

$\frac{2\pi}{b}= \pi$

is the period.

This implies that

$b=2$

$\frac{b}{c} = 1$

is the phase shift.

This implies that;

$c = 2$

$d = 2$

is the vertical shift.

The possible equations are:

$y = \pm \: 3 \cos(2x \pm2)+2$

Find (x³+x²-20x+24) divided by (x-3)

Rus_ich [418]

Answer:

$\frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8$

Step-by-step explanation:

Given;

p(x) = x³ + x²- 20x + 24

factor of p(x) = x-3

Apply long division method;

x² + 4x - 8

------------------------------

x - 3 √ x³ + x²- 20x + 24

-( x³ - 3x²)

-------------------------------

4x² - 20x + 24

-(4x² -12x )

-------------------------------

-8x + 24

- (-8x + 24)

-----------------------------------------

0

$thus, \ \frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8$
