Use the REMAINDER THEOREM to explain whether or not (x-2) is a factor of F(x)=x^4-2x^3+3x^2-10x+3

Answers

$(P(x))/(R(x))|(D(x))/(Q(x))$

$\frac{x^4-2x^3+3x^2-10x+3}{}|\frac{x-2}{}$

$(x^4-2x^3+3x^2-10x+3)/(-x^4+2x^3)|(x-2)/(x^3)$

$(3x^2-10x+3)/(-3x^2+6x)|(x-2)/(x^3+3x)$

$(-4x+3)/(4x-8)|(x-2)/(x^3+3x-4)$

$\frac{-5}{}|(x-2)/(x^3+3x-4)$

$\boxed{\boxed{(x^4-2x^3+3x^2-10x+3)/(-5)|(x-2)/(x^3+3x-4)}}$

| n + 2 | ≥ 1 please explain it if you can thank you

Answers

Answer:

(n ≤ -3) ∪ (-1 ≤ n)

Step-by-step explanation:

I like to "unfold" the absolute value expression by copying the right-side expression to the left side (with the same comparison symbol) and negating its value. I do it this way because I find it easier to work the problem "all at once".

-1 ≥ n +2 ≥ 1

Obviously, -1 ≥ 1 is not true, which means the solution to this inequality will be disjoint sections of the number line. A compound inequality of this nature is generally interpreted to mean the AND of the two inequalities. So, technically, this is an incorrect step. I choose to overlook that, and consider the expression to represent the two inequalities ...

-1 ≥ n +2 . . . OR

n +2 ≥ 1

Subtracting 2 from the above compound inequality gives ...

-3 ≥ n ≥ -1

So, the solution is ...

(n ≤ -3) ∪ (-1 ≤ n)

_____

Further explanation

The inequality symbol negates its content if that content is negative. So, the expression ...

|n+2| ≥ 1

means ...

±(n +2) ≥ 1

This resolves to two cases:

n +2 ≥ 1

and

-(n +2) ≥ 1

The latter case is equivalent to ...

n +2 ≤ -1

which can also be written as ...

-1 ≥ n +2

A more technically correct solution process would identify the two cases and work them separately.

In the graph, the red shading (with the solid edge) shows the solution with respect to the numbers on the x-axis. If you were to graph this on a number line, you would put solid dots at -3 and -1, and shade the line to their left and right, respectively. The blue curve shows the absolute value, and the green line shows y=1, so you can see that the shaded areas correspond to the absolute value being greater than or equal to 1.

A dance floor is made from square wooden tiles with a side length of 1 foot. the floor can be laid out as a square or as a rectangle. Yeasmin chooses a rectangular dance floor for her party. The width of the rectangular dance floor is 10 feet less than the width of the square dance floor, and its length is 15 greater than the length of the square floor.how much greater is the length of the rectangular dance floor than its width?
The perimeter of the rectangular dance floor is 130 feet. What are the length and width of the dance floor?
If the unit rate is $0.50 per tile, how much would it cost Yeasmin to buy the number of tiles needed to make up the dance floor

Answers

legnth/width for square = x
width of rectangle= x-10
legnth of rectangle=x+15
so (x-10)+25=x+15 which is the first part

part two
the perimiter of rectangle floor =130
perimiter= 2width+2legnth so 130/2=width+height
width=x-10 and legnth=x+15 so
x-10+x+15=130/2
2x+5=75
minus 5 from both sides
2x=70
divide by two
x=35 which is legnth/width of the square, but we want the legnth and width of the rectangle so
x-10=width=25
x+15=legnth=50
so the cost of the floor is (50 times 25)times $0.50 or
(50 times 25)/2 so
$525
