5 0

What it means is you add them all together then you divide by how many numbers are there. The answer is 6 because 8+6+4=18 then you divide 18 by 3 and get 6.

Mean = Sum / number

Mean = (8 + 6 +4) / 3

= 18 / 3

= 6

Mean = 6

Graph the image of this triangle after a dilation with a scale factor of 2 centered at the origin. Use the polygon tool to graph

Olenka [21]

The triangle is illustrated below.

<h3>How to explain the triangle?</h3>

The first thing you should find are the new vertices:

(x, y) ---> (2x, 2y) ---> (x', y')

(0, 0) ---> (2 (0), 2 (0)) ---> (0, 0)

(-4, 4) ---> (2 (-4), 2 (4)) ---> (-8, 8)

(-4, -2) ---> (2 (-4), 2 (-2)) ---> (-8, -4)

Then, you must join the ordered pairs and graph the new triangle.

See the attached graph.

Which of the following expressions is equivalent to (8x)^2/3 ?

miv72 [106K]

Answer:

Step-by-step explanation:

Given the expression (8x)^2/3

This can also be expressed as;

(8x)^2/3

= (2^3x)^2/3

= (2³)^2/3 * x^2/3

= 2^2 * x^2/3

= 4x^2/3

Hence the equivalent expression is 4x^2/3

Answer:

$1.5

Step-by-step explanation:

12 x 1.75 + 6c = 30

21 + 6c = 30

6c = 30 - 21

6c = 9

c = 9/6

c = 1.5

A kite flying in the air has a 12 - ft line attached to it. its line is pulled taut and casts a 10 - ft shadow. find the height

tekilochka [14]

The height of the kite will be 6.6 ft rounded to the nearest tenth.

<u><em>Explanation</em></u>

According to the below diagram, AB is the height of the kite and AC is the 12 ft line attached to it.

The line is pulled taut and casts a 10 ft shadow. That means BC = 10 ft

Now, in right angle triangle ABC, using <u>Pythagorean theorem</u>....

$(AB)^2 +(BC)^2 = (AC)^2 \\ \\ (AB)^2 +(10)^2 = (12)^2 \\ \\ (AB)^2 +100 = 144\\ \\ (AB)^2 = 144-100 =44\\ \\ AB=\sqrt{44}= 6.6332....$

So, the height of the kite will be 6.6 ft rounded to the nearest tenth.
