Um poliedro convexo tem 8 vertices e 10 a resta.quantas faces ele tem ?
Maurinko [17]

Answer:

la respuesta es 15. Esto proviene de una de las ecuaciones de Euler. En 1750, señaló en una carta a Christian Goldbach que en un poliedro convexo

V - E + F = 2

donde V es el número de vértices, E es el número de aristas y F es el número de caras. En su pregunta, V = 10 y F = 8, por lo que la ecuación se convierte en

10 - E + 7 = 2

17 - E = 2

E = 16

The relationship between the distance run and the time for Amy can be represented by the equation Y equals 17.45X, where she ran
Kipish [7]

Question;

Assumption:

Let us assume Brandon's running speed is = 18.30 and

Ruben's running speed is = 16.50 and

Answer:

The two equations that can represent the relationship between the meters and second for Brandon and Ruben are;

Brandon → Y₁ = 18.3·X₁ and

Ruben → Y₂ = 16.5·X₂

Step-by-step explanation:

The equation is of the form

Y = 17.45·X

That is Amy ran Y meters in X seconds

Therefore we have

17.45 = \frac{Y}{X} or the value 17.45 is the running speed of Amy

Therefore, where the running speed of Brandon is 18.30  and the running speed of Ruben is 16.50  we have

Y meters ran by Brandon in X seconds given by

Y₁ = 18.3·X₁ and

For Ruben we have Y meters ran in X seconds given by

Y₂ = 16.5·X₂.
