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

You are looking at the New York ball drop on New Year’s Eve at a distance of 100 m away from the base of the structure. If the b
Fofino [41]

The question is an illustration of related rates.

The rate of change between you and the ball is 0.01 rad per second

I added an attachment to illustrate the given parameters.

The representations on the attachment are:

\mathbf{x = 100\ m}

\mathbf{\frac{dy}{dt} = 2\ ms^{-1}} ---- the rate

\mathbf{\theta = \frac{\pi}{4}}

First, we calculate the vertical distance (y) using tangent ratio

\mathbf{\tan(\theta) = \frac{y}{x}}

Substitute 100 for x

\mathbf{y = 100\tan(\theta) }

\mathbf{\tan(\theta) = \frac{y}{100}}

Differentiate both sides with respect to time (t)

\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}

Substitute values for the rates and \mathbf{\theta }

\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}

This gives

\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}

\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}

Divide both sides by 2

\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }

\mathbf{ \frac{d\theta}{dt} = 0.01 }

Hence, the rate of change between you and the ball is 0.01 rad per second
