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.

13. The processes of extracting and separating gold in remote regions often results in
Amiraneli [1.4K]

The processes of extracting and separating gold in remote regions often result in environmental contamination with Cyanide (Option B).

<h3>What is cyanide?</h3>

Cyanide is a substance that contains a group formed by Carbon and Nitrogen forming a strong chemical bond (C≡N).

Cyanide can be very toxic when forms soluble salts (e.g., sodium and/or potassium cyanide).

Cyanide was used as a chemical compound during gold extraction, thereby generating environmental contamination.

Can someone please help me with this?<br> Let f(x) = x^3 + x + 1. Which expression
Tatiana [17]

Answer:

Last Option

Explanation:

I'm not sure about this one so I had to google the equation real quick.

The equation for the derivative of an inverse is:

[f^{-1}(x)]'=\frac{1}{f'(f^{-1}(x))}

From my understanding of the format, it might look like a hard equation to understand but its pretty simple.

The inverse derivative is 1 divided by the derivative of f(x), except you plug in f⁻¹(x) into that derivative.
