<h2><u>El conjunto de parejas ordenadas que no es una función es: </u></h2><h2> </h2><h2><u>Alternativa C: {(-2,1),(-1,0),(0,1),(-1,2),(2,2)} </u></h2>

<h3>Una función se define como un conjunto de parejas ordenadas (x, y) donde no se repite el valor de "x" (corresponde al dominio de la función) </h3><h3> </h3><h3>En el caso específico del ejercicio, la alternativa C no corresponde con una función ya que tienen dos parejas con el mismo valor de "x":  {(-2,1), (-1,0), (0,1), (-1,2), (2,2)} </h3><h3> </h3><h3>Estos pares están en negrita, y el valor repetido subrayado. </h3>

2. \frac{2sin(\alpha)cos(\beta) - sin(\alpha - \beta)}{cos(\alpha - \beta) - 2sin(\alpha)sin(b)} = tan(\alpha + \beta)
    \frac{2sin(\alpha)cos(\beta) - sin(\alpha)cos(\beta) + cos(\alpha)sin(\beta)}{cos(\alpha)cos(\beta) + sin(\alpha)sin(\beta) - sin(\alpha)sin(\beta)} = tan(\alpha + \beta)
    \frac{sin(\alpha)cos(\beta) + cos(\alpha)sin(\beta)}{cos(\alpha)cos(\beta) - sin(\alpha)sin(\beta)} = tan(\alpha + \beta)
    \frac{sin(\alpha + \beta)}{cos(\alpha + \beta)} = tan(\alpha + \beta)
    tan(\alpha + \beta) = tan(\alpha + \beta)

Mandarinka [93]

Answer:

45 different ways to fill the positions.

Step-by-step explanation:

Consider the provided information.

Management selection. A corporation plans to fill 2 different positions for vice-president, V₁ and Upper V₂, from administrative officers in 2 of its manufacturing plants. Plant A has 9 officers and plant B has 5.

We need to find the probability that 2 positions be filled if the Upper V₁ position is to be filled from plant A and the Upper V₂, position from plant B?

To fill the post of V₁ from plant A, which has 9 officers, we have 9 ways.

To fill the post of V₂ from plant B, which has 5 officers, we have 5 ways.

Therefore, the total number of ways are: 9\times 5=45

Hence, 45 different ways to fill the positions.
