Answer: (16) B       (17) C       (18) A       (19) C        (20) B

<u>Step-by-step explanation:</u>

16.\quad \bigg|\dfrac{m}{6}\bigg|>3\\\\\\.\quad \quad \dfrac{m}{6}>3\qquad or \qquad \dfrac{m}{6}

        m > 18      or        m < -18

17.  -5 | 2b - 8| > -90

          | 2b - 8| < 18

     2b - 8 < 18        or     2b - 8 > -18

           2b < 26                    2b > -10

             b <  13       or            b > -5

18.\quad \dfrac{|-2+6b|}{6}

        | -2 + 6b| < 30

         -2 + 6b < 30      or     -2 + 6b > -30

                6b < 32                      6b > -28

                 b < 32/6                       b > -28/6

                 b < 16/3      or              b > -14/3

19)    |9 - 2x| - 4 ≤ -1

            |9 - 2x|  ≤ 3

               9 - 2x ≤ 3     or      9 - 2x ≥ -3

                   -2x ≤ -6                 -2x ≥ -12

                      x ≥  3     or             x ≤  6

20)   | 5 - 6x | - 2 < 53

            | 5 - 6x |  < 55

                5 - 6x < 55     or    5 - 6x > -55

                    -6x < 50                 -6x > -60

                       x > -50/6                x < 10

                      x > -25/3

For accounting purposes, the value of assets (land, buildings, equipment) in a business depreciates at a set rate per year. The
sladkih [1.3K]
For this case we have an equation of the form:
 
V (t) = V0 * (b) ^ t&#10; 
 Where,
 v0: initial value in assets
 b: depreciation rate
 t: time in years.
 Substituting values we have:
V (t) = 408000 * (0.82) ^ t&#10;
 For year 8 we have:
V (t) = 408000 * (0.82) ^ 8&#10; V (t) = 83400.94703
 Rounding off we have:
 V (t) = 83401
 Answer:
 
the value of V0 and b are:
 
V0 = $ 408,000
 
b = 0.82
 
the value of the assets after 8 years is:V (t) = 83401 $
