Question
Chapter SH, Problem 7.18EP
a.
To determine
To find the annual percentage decrease of the population.
a.
Expert Solution
Answer to Problem 7.18EP
5% .
Explanation of Solution
Given:
The given table is
Calculation:
The decrease in the population of wolf from 2005 to 2006 is,
=420−399=21
So, the percentage decrease will be,
=21420×100=5%
Hence, the annual percentage decrease is 5% .
b.
To determine
To write the logarithmic function for the time in years.
b.
Expert Solution
Answer to Problem 7.18EP
y=425.527−47.548lnx .
Explanation of Solution
Given:
The function that models the yearly sales of cell phones,
s(t)=0.45t4+5.4t3−15t2−300t+1000
Calculation:
Use Ti-82 to solve find logarithmic function,
Press STAT
Now, press 1 and enter the data in the following window,
Now, go to CALC and choose LNREG
Press ENTER
So, the logarithmic function that defines the population will be
y=a+blnxa=425.527b=−47.548
c.
To determine
To find the number of wolves in 2020 .
c.
Expert Solution
Answer to Problem 7.18EP
293.69 .
Explanation of Solution
Given:
The function that models the yearly sales of cell phones,
s(t)=0.45t4+5.4t3−15t2−300t+1000
Calculation:
Number of wolves in 2020 will be,
Consider the following expression,
y=a+blnxa=425.527b=−47.548
Substitute the value of x=16 as in the above expression,
y=425.527−47.548lnxy=425.527−47.548ln16y=293.69
Hence, the population of wolf in the year will be 293.69
