Answer:

v = 2

Explanation:

8(2 − 6v) + 19 = −61

[ Simplify both sides of the equation ]

8(2 − 6v) + 19 = −61

(8)(2) + (8)(−6v) + 19 = −61 (Distribute)

16 + −48v + 19 = −61

(−48v) + (16 + 19) = −61 (Combine Like Terms)

−48v + 35 = −61

[ Subtract 35 from both sides ]

−48v + 35 − 35 = −61 − 35

−48v = −96

[ Divide both sides by -48 ]

−48v / -48 = −96 / -48

v = 2

A mountain climber's change in elevation over an 8-hour period is −248 feet . What is the mountain climber's average change in e

Amiraneli [1.4K]

It is given that the mountain climber's change in elevation over an 8-hour period is −248 feet. Therefore, to find the average change in elevation per hour for that time period all that we need to do is divide the total change in elevation by the the time taken.

Therefore, average change= $\frac{-248}{8}=-31$ feet

Therefore, the first option is the correct option.

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 ...

500 units

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

60 units

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

100 units

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 increases as the number of units produced rises. (The minimum average cost is at a production level of about 224 units.)
