Triangle ABC is translated 3 units to the left and downward 10 units to form triangle A'B'C', then dilated by a factor of 2 to f
11Alexandr11 [23.1K]

Triangle A"B"C" are similar triangles to triangle ABC and all corresponding angles are congruent. Also, triangle A"B"C" is twice the size of triangle ABC.

<h3>What is transformation?</h3>

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

Translation is the movement of a point either <em>up, left, right or down</em> in the coordinate plane.

Triangle ABC is translated 3 units to the left and downward 10 units to form triangle A'B'C', then dilated by a factor of 2 to form triangle A''B''C''.

Hence:

Triangle A"B"C" are similar triangles to triangle ABC and all corresponding angles are congruent. Also, triangle A"B"C" is twice the size of triangle ABC.

Can anyone math experts help and guide me through these questions❓
Lubov Fominskaja [6]

Step-by-step explanation:

The volume of a cube is

a {}^{3}

where a is the side length,

Note: If you want to remember this formula, know that a cube is basically a bunch of squares stacked on one another vertically and horizontally

The area of a square with side length a, is

{a}^{2}

If we multiply that by the height of the cube, which is a.

{a}^{2}  \times a =  {a}^{3}

That is the easy way to derive the formula of the volume of a cube.

Back on track, we know the volume so we must solve for a.

1.

125 =  {a}^{3}

Assuming you took algebra, to isolate the variable a, we must undo it being raised to the third power.

To do this, we take the cube root of both sides

\sqrt[3]{125}  =  \sqrt[3]{a {}^{3} }

The cube root of 125 is 5 so

5 = a

5 cm

2.

8 =   {a}^{3}

\sqrt[3]{8}  =  \sqrt[3]{ {a}^{3} }

2 = a

2 ft

3.

343 =  {a}^{3}

a = 7

7 yd

4.

1000 = a {}^{3}

10 = a

10 mm

5.

1728 =  {a}^{3}

a = 12

12 in. or 1 ft

6.

1 =  {a}^{3}

a = 1

1 m
