The number of deer after
(a)
Answer to Problem 52PPS
The number of deer after
Explanation of Solution
Given information: The number of Deer
Calculation: From (1) the number of deer after
(b)
Draw a table that shows the population of deer every year for next five years.
(b)
Answer to Problem 52PPS
Time (t) | Number of Deer (D) |
0 | 100*20 = 100 |
1 | 100*20.5 = 141 |
2 | 100*21 = 200 |
3 | 100*21.5 = 282 |
4 | 100*22 = 400 |
5 | 100*22.5 = 565 |
Explanation of Solution
Given information: The number of Deer
Calculation: From (1) the number of deer for the next five years can be evaluated by plugging
Time (t) | Number of Deer (D) |
0 | 100*20 = 100 |
1 | 100*20.5 = 141 |
2 | 100*21 = 200 |
3 | 100*21.5 = 282 |
4 | 100*22 = 400 |
5 | 100*22.5 = 565 |
(c)
Show the graph for number of deer verses time with the help of table obtained.
(c)
Explanation of Solution
Given information: The number of Deer
Graph: The graph for the number of deer verses the time is shown as,
(d)
With the help of graph and table decide whether it is a reasonable trend over the long period. Explain.
(d)
Answer to Problem 52PPS
No, it is not reasonable trend over the long period.
Explanation of Solution
Given information: The number of Deer
Calculation: From the table and graph of the number of deer verses the time it can be said that the number of deer grows rapidly. And as seen from the number of deer graph it can be observed that the deer grows rapidly in small interval of time and the graph line for the population of deer is approaching to y-axis. Therefore, for the long term period it is not reasonable to say anything about the trend because there are many factors like environment conditions, temperature and rate of death etc. which can affect the deer population for long term.
