olya-2409 [2.1K]

9514 1404 393

Answer:

Step-by-step explanation:

A regular nonagon has vertices that are 360°/9 = 40° apart. Any rotation by a multiple of 40° will make the figure indistinguishable from the original.

Rotational symmetry of 40° applies.

Rotational symmetry of 200° applies.

Step-by-step explanation:

Hey there!

According to the question, you need to find out the distance from your friend's house to school.

Firstly figure out the coordinate of your school and school. Then use formula of distance.

So, we find the coordinates as (7,7) and (5,0).

So, x 1 = 7 y1= 7

x 2 = 5 y2 = 0

~ Use distance formula.

$d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} }$

~ Put all values.

$d = \sqrt{ {(5 - 7)}^{2} + ( {0 - 7)}^{2} }$

~ Simplify it.

$d = \sqrt{ {( - 2)}^{2} + {( - 7)}^{2} }$

$d = \sqrt{4 + 49}$

$d = \sqrt{53}$

D= 7.280

Therefore, the distance between your friend's house and your school is 7.3 units.

Hope it helps....

A circle has a 10 centimeter radius. Find the area of the circle to the nearest tenth. (Use 3.14 for ?)

pickupchik [31]

Answer:

314.2 cm^2

Step-by-step explanation:

The formula for the area of a circle of radius r is A = 3.14r^2.

With r = 10 cm, r^2 = 100 cm^2, and so the area of this circle is 314.2 cm^2, to the nearest tenth.

What is the area of the trapezoid?

tensa zangetsu [6.8K]

Answer:

24 square units

Step-by-step explanation:

For Trapezoid

a = 8

b = 4

h = 4

Area of Trapezoid

A = a + b/2 * h

= 8 + 4/2 * 4

= 12/2 *4

= 6 * 4

= 24

Thus, the area of the trapezoid is 24 square units
