Chapter 10.5, Problem 27PS
Solution

(a)

To calculate: The sinusoidal model for N as a function of t .

The sinusoidal model for the given data is N=3.68sin0.77t−0.703+20.37 .

Given information: The given table shows the number of employees N in thousands and time t measured in years.

    t1234567891011
    N20.822.724.623.22017.516.717.8212224.1

Calculation:

To find the sinusoidal model for the given data, follow the below steps in a graphing calculator.

Press “ON” button on the graphing calculator. Enter the keys STAT1 and enter the given data. Enter the number of adults under L1 and time under L2 .

Figure (4)

From the above figure, the model appears to be a good fit.

Therefore, the sinusoidal model for the given data is N=3.68sin0.77t−0.703+20.37 .

(b)

To calculate: The number of employees in the twelfth year.

The number of employees in the twelfth year will be 23220 .

Given information: The given table shows the number of employees N in thousands and time t measured in years.

    t1234567891011
    N20.822.724.623.22017.516.717.8212224.1

Calculation:

From part (a), the sinusoidal model for the number of employees and time is N=3.68sin0.77t−0.703+20.37 .

Substitute 12 for t in the above model.

  N=3.68sin0.7712−0.703+20.37=3.68sin8.537+20.37=3.680.77+20.37=23.22

Thus, number of employees in the twelfth year will be 23220 .
