Answer:

8 times

Step-by-step explanation:

An octagon has eight sides of equal length and eight angles of same measure. So, If it is rotated 360 degrees about its center. It would coincide with all of its 8 sides. So, it will coincide with it's pre-image 8 times.

Answer:

Step-by-step explanation:

because A regular octagon is a closed figure with sides of the same length and internal angles of the same size. so if it is rotated 360 degrees it should coincide with its preimage after every 45 degrees.

so 360/45= 8 times

Suppose f(x)=x^2 and g(x)=5x^2. Which steamy best compares the graph of g(x) with the graph of f(x)?
ankoles [38]

By understanding and applying the concepts of dilation and <em>quadratic</em> functions, the function g(x) is a <em>vertically dilated</em> version of f(x) by a factor of 5.

<h3>How to compare the graphs of two functions</h3>

In this questions we know two <em>quadratic</em> equations of the form y = a · x². f(x) is known as the <em>canonical</em> function as a = 1 and g(x) is the consequence of <em>dilating</em> f(x) <em>vertically</em> by a factor of 5. Now we proceed to present graphically between the two functions.

In a nutshell, the function g(x) is a <em>vertically dilated</em> version of f(x) by a factor of 5.

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g –
Sveta_85 [38]
F(x) = 4 - x^2
g(x) = 6x
(g - f)(x) = g(x) - f(x) = 6x - (4 - x^2) = 6x - 4 + x^2
(g - f)(3) = 6(3) - 4 + 3^2

Name the quadrant that point A lies inA) Quadrant IB) Quadrant IIC) Quadrant IIID) Quadrant IV
Blizzard [7]

Given the figure, we can deduce the following information:

1. Point A lies in the upper left side of the Cartesian Plane.

Based on the given figure, we must note that if the point lies in the upper left side of the Cartesian Plane or the x-coordinate is negative but the y-coordinate is positive, it should be in the Quadrant II.

Therefore, the answer is B. Quadrant II.

the area of a rectangle is 4,320 ft2. the ratio of the length to the width is 6:5. find the length of the rectangle. a. 12 ft b.
xeze [42]
Let the length of the rectangle = 6x and the width = 5x
Area = 6x(5x) = 30x^2 = 4,320
x^2 = 4,320/30 = 144
x = 12 ft

Therefore, length = 6x = 6(12) = 84 ft

Help would be much appreciated! :)​
Tju [1.3M]

Answer:

\displaystyle \frac{x^4 + 10x^3 + 25x^2 + 3x - 24}{x^2 + 5x - 4} = x^2 + 5x - 4 + \frac{3x - 8}{x^2 + 5x - 4}

General Formulas and Concepts:

<u>Algebra I</u>

Terms/Coefficients

  • Expanding

<u>Algebra II</u>

Polynomial Division

  • Long Division
  • Synthetic Division

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

<em />\displaystyle \frac{x^4 + 10x^3 + 25x^2 + 3x - 24}{x^2 + 5x - 4}<em />

<em />

<u>Step 2: Long Division</u>

<em>See attachment.</em>

  1. Multiply quotient <em>a</em> and divisor, then subtract from dividend:                      \displaystyle x^2(x^2 + 5x - 4) = x^4 + 5x^3 - 4x^2 \leftarrow \text{red 1}
  2. Multiply quotient <em>b</em> and divisor, then subtract from new dividend:              \displaystyle 5x(x^2 + 5x - 4) = 5x^3 + 25x^2 - 20x \leftarrow \text{red 2}
  3. Multiply quotient <em>c</em> and divisor, then subtract from new dividend:              \displaystyle 4(x^2 + 5x - 4) = 4x^2 + 20x - 16 \leftarrow \text{red 3}
  4. Write remainder:                                                                                               \displaystyle \frac{r(x)}{b(x)} = \frac{3x - 8}{x^2 + 5x - 4}
