A series of transformations maps EFGH onto its image. Determine the series of transformations involving a reflection, translatio

Annette [7]

Answer:

See below

Step-by-step explanation:

Firstly, we'll dilate EFGH by any scale factor.

<u><em>Let's find the scale factor first.</em></u>

=> Scale Factor = $\frac{Side \ of \ dilated \ figure}{Side \ of \ original \ figure}$

=> Scale Factor = $\frac{6}{4}$

=> Scale Factor = 1.5

1) Dilate the figure by a scale factor of 1.5

2) Reflect it across the origin

3) Translate (Move) 5 units down and then 10 units left.

These transformations will map EFGH onto its image.

A piece of cloth is required to completely cover a solid object. The solid object is composed of a hemisphere and a cone surmoun

Otrada [13]

Answer:

▶(B) 463.39 m²

<h3>Step-by-step explanation:</h3>

$\space$

Surface area of hemisphere = 2πr²

=> 2×22/7× (7)² = 308 m²

☯<u>For calculating the surface area of a cone we need to calculate its slant height,</u>

$\sf{ \leadsto \: 1 = \sqrt{49 + 1} = \sqrt{50 \: } m}$

$\space$

$\sf{ \leadsto \: \pi \ r1 = \frac{22}{7} \times 7 \times \sqrt{50} = 463.39 \: {m}^{2} }$

$\: \:$

Hope it helps!

Have a great day! :)

A line is drawn through (–7, 11) and (8, –9). The equation y – 11 = (x + 7) is written to represent the line. Which equations al

IRISSAK [1]

Answer:

3y+4x=5

Step-by-step explanation:

step 1

Find the slope

we have

(–7, 11) and (8, –9)

m=(-9-11)/(8+7)

m=-20/15

m=-4/3

step 2

Find the equation of the line into point slope form

we have

m=-4/3

point (-7,11)

substitute

y-11=-(4/3)(x+7) ----> equation of the line into point slope form

Multiply by 3 both sides

3y-33=-4(x+7)

3y-33=-4x-28

3y+4x=33-28

3y+4x=5 -----> equation of the line into standard form
