The answers is -36 because you only have to add all the numbers (you only add a negative number when is the same sing y is not negative you don’t have to add you have to subtract the number) hope it helps

Find the missing factor 6s^2-7s-5=(3s-5)()
victus00 [196]
Answer: 2s + 1


Explanation:

1) Given expression: 6s² - 7s- 5 = (3s - 5) (        )

2) The missing factor (     ) is such that when it is multiplied by (3s - 5) the product is 6s² - 7s- 5.

3) Since the first term of the first factor starts with 3s, the first term of the second factor shall be 2s (since they have to yield 6s²). Then, you can write:

6s² - 7s- 5 = (3s - 5) (2s +    )

4) The second term of the missing factor is positive because the product (+)(-) = (-) which is the sign of the third term of the polynomial.

5) The second term is such that when multiplied by - 5 is equal to the last term of the polynomial (also - 5), so this second terms is +1.

And you get: 6s² - 7s- 5 = (3s - 5) (2s +  1)

6) You can expand, using distributive property to confirm the result:

(3s - 5) (2s +  1 ) =  (3s)(2s)  + (3s)(1) - (5)(2s) -(5)(1) =  6s² - 7s- 5, which confirms the result.

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.)
