The ratio of the sides EF/LM after the transformation is 1/8

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>rotation, translation, reflection and dilation.</em>

Dilation is the increase or decrease in size of a figure by a factor while translation is the movement of a point up, down, left or right.

Given the tansformation:

(x,y) → (8x, 8y) → (x - 4, y - 4).
This means a dilation of CDEF by 8 and translated 4 units down and 4 units left.

Hence:

LM = 8 * EF

EF/LM = 1/8

The ratio of the sides EF/LM after the transformation is 1/8

Question 3(Multiple Choice Worth 2 points)

zysi [14]

The solution to the equation are 5 or -1 after applying the quadratic formula.

<h3>What is a quadratic equation?</h3>

Any equation of the form $\rm ax^2+bx+c=0$ where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

It is given that:

x² - 4x² - 5 = 0

The above equation is a quadratic equation:

Using the quadratic formula:

$\rm $x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$$

Plug the values in the formula:

$\rm $x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(-5)}}{2(1)}$$

After solving:

x = 5 or -1

Thus, the solution to the equation is 5 or -1 after applying the quadratic formula.

How to solve 3x-4(8x-6)=20

11Alexandr11 [23.1K]

3x -4(8x - 6) = 20

3x -32x + 24 = 20

-29x = -4

29x = 4

x = $\frac{29}{4}$ = 7.25

What is the volume of the following triangular pyramid?

Readme [11.4K]

Answer:

The volume of the triangular pyramid

V = 566.66 in³

Step-by-step explanation:

<u><em>Step(i):-</em></u>

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

Base area = Area of the triangle

$A= \frac{1}{2} X base X height$

Given the base of the triangle (b) = 17in

Given Height of the triangle (h ) =10 in

$A= \frac{1}{2}( 17 ) (10) = 85$

The base area of the pyramid ( A) = 85 in²

<u><em>Step(ii):-</em></u>

<u><em>Given the height of the pyramid (h) = 20in</em></u>

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

The volume of the triangular pyramid

= $= \frac{1}{3}( 85)(20) = 566.66$

<u><em>Final answer:-</em></u>

The volume of the triangular pyramid

V = 566.66 in³

In the figure, angle ABC and angle ADB are each right angles. Additionally, AC = 17.8 units and AD = 5 units. What is the length

Marizza181 [45]

Answer:

DB = 8

Step-by-step explanation:

Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is

$\frac{DB}{DC}$ = $\frac{AD}{BD}$ , substitute values

$\frac{DB}{17.8-5}$ = $\frac{5}{BD}$

$\frac{DB}{12.8}$ = $\frac{5}{BD}$ ( cross- multiply )

DB² = 64 ( take the square root of both sides )

DB = $\sqrt{64}$ = 8
