1) Calcula la diagonales de un poligono n lados. Heptágono: 2 puntos

ahrayia [7]

Answer:

El número de diagonales de un polígono de n lados se calcula mediante la siguiente fórmula:

$d = \frac{n\cdot (n-3)}{2}$ (1)

Donde:

$d$ - Cantidad de diagonales del polígono.

$n$ - Cantidad de lados del polígono.

Bajo esta fórmula, tenemos los siguientes resultados:

a) El heptágono tiene 14 diagonales.

b) El octágono tiene 20 diagonales.

c) El eneágono tiene 27 diagonales.

d) El decágono tiene 35 diagonales.

e) El pentadecágono tiene 90 diagonales.

Explanation:

La cantidad de diagonales de un polígono se puede determinar mediante la siguiente ecuación:

$d = \frac{n\cdot (n-3)}{2}$ (1)

Donde:

$d$ - Cantidad de diagonales del polígono.

$n$ - Cantidad de lados del polígono.

A continuación, calculamos la cantidad de diagonales de los siguientes polígonos:

Heptágono ( $n = 7$ )

$d = \frac{7\cdot (7-3)}{2}$

$d = 14$

El heptágono tiene 14 diagonales.

Octágono ( $n = 8$ )

$d = \frac{8\cdot (8-3)}{2}$

$d = 20$

El octágono tiene 20 diagonales.

Eneágono ( $n = 9$ )

$d = \frac{9\cdot (9-3)}{2}$

$d = 27$

El eneágono tiene 27 diagonales.

Decágono ( $n = 10$ )

$d = \frac{10\cdot (10-3)}{2}$

$d = 35$

El decágono tiene 35 diagonales.

Pentadecágono ( $n = 15$ )

$d = \frac{15\cdot (15-3)}{2}$

$d = 90$

El pentadecágono tiene 90 diagonales.

It was the first civil war. Additionally, after the Civil War, 3 amendments were added to the Constitution that made it legal for the freedmen to vote. This allowed for new issues and a new movement to allow women to vote. After the civil war, segregation was implemented and that created the Civil Rights Movement to get rid of segregation. Hope this helps.

What impact does globalization have on society?

AURORKA [14]

The correct answer is - Native cultures adopt some foreign customs.

The globalization is a process that spreads and promotes lot of things around the world, one of which is the culture. The native cultures often tend to adopt foreign customs through the globalization. The reasons for this can be seen in the fact that they can be useful, they seem more ''cool'', the people want to keep pace with the developed world, but also because of the media and propaganda. While this may be nice in a sense of uniting the world, it is also very harmful toward the native cultures, as the younger generations tend to be focused on the foreign one and neglect their own one, so many cultures are on the verge of dying out.
