Answer:

  • x = 3.58

Step-by-step explanation:

  • e^{4x - 5} - 7 = 11243
  • e^{4x - 5} = 11250
  • ln e^{4x - 5} = ln 11250
  • 4x - 5 = ln 11250
  • 4x - 5 = 9.33 (rounded)
  • 4x = 14.33
  • x = 14.33 / 4
  • x = 3.58 (rounded)

kirill [66]

Part A:

x - total number of liters ( milk + water )

0.2 x + 1 = x

Part B :

0.2 x + 1 = x

0.8 x = 1

x = 1 : 0.8 = 1.25 lit.

Milk:

1.25  x  0.2 = 0.25 lit.

The average cost per unit for the production of a certain brand of DVD is given by C=\frac{500+60c+0.01x^2}{x} , where x is the
Ganezh [65]

Answer:

  A: for 500: 66; for 60: 68.9; for 100: 66

  B: no

Step-by-step explanation:

We assume your average cost function is ...

  \overline{C}=\dfrac{0.01x^2+60x+500}{x}

A. The overline over the C indicates it is an average value.

Evaluating the cost function at the different production levels, we find the average cost per unit to be ...

<u>500 units</u>

  c = ((0.01·500)+60)500 +500)/500 = 65 +1 = 66

<u>60 units</u>

  c = ((0.01·60 +60)·60 +500)/60 = 60.6 +500/60 ≈ 68.93

<u>100 units</u>

  c = ((0.01·100 +60)·100 +500)/100 = 61 +5 = 66

__

B. Dividing out the fraction, we find that the cost per unit is ...

  0.01x +60 +500/x

As x gets large, this approaches the linear function c = 0.01x +60. This <em>increases</em> as the number of units produced rises. (The minimum average cost is at a production level of about 224 units.)
