Answer:

Costo fijo= $104.5

Costo unitario=  $0.5 por minuto

Step-by-step explanation:

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

<u>Primero debemos calcular el cost por minuto de llamada:</u>

Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario=  $0.5 por minuto

<u>Ahora, el costo fijo:</u>

Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5

100 POINTS!!!! Create a table of values for a linear function. A drone is in the distance, flying upward in a straight line. It
dangina [55]
Based on the docx you showed me, the equation for the parabola is y = x^2 + 36 and you want a table of values for a linear equation that intersects the parabola at (5, 6) and (-2, 34).

If you use these two points to create a line we get the equation:

y - 6 = \frac{34 - 6}{-2 - 5}(x - 5) (I just used point slope form)

This can be simplified to:

y = \frac{40}{-7}x + \frac{242}{7}

Now we just need to create a table of points on this line. We already have the points you gave and we can also use the y-intercept: (0, \frac{242}{7}) and the x-intercept: (\frac{121}{20}, 0).

So our table of value can be:

x          | y
______|________
-2         | 34
0          | 242 / 7
5          | 6
121/20 | 0

The cost C in dollars of manufacturing x bicycles at a production plant is given by the function shown below.
Andreas93 [3]

Answer:

  • Minimum 100 bicycles
  • Minimum cost is 13500

Step-by-step explanation:

<u>Given function:</u>

  • C(x) = 3x^2- 600x + 43500

a.

Minimum cost is obtained at vertex.

Vertex is determined by formula x = -b/2a, in standard form of

f(x) = ax^2 + bx + c

<u>Vertex of the given function is:</u>

  • x = -(-600)/(2*3) = 100

b.

<u>Cost at vertex is:</u>

  • C(100) = 3*100^2 - 600*100 + 43500 = 13500
