a.
Graph of derivative of fruit fly population. What unit should be used for horizontal and vertical axis.
a.
Answer to Problem 7E
The graph derivative is given.
Explanation of Solution
Given:
The given graph of the population is :
Calculation:
Estimate the slope of graph
At point A slope is 10, at point B slope is 14 and at point C slope is 19 . Tracing these points will give the graph of derivative. horizontal axis represents
The graph of derivative is given below:
b.
To find: During what days population seem increasing fastest and slowest.
b.
Answer to Problem 7E
During 15th to 25thdays population increasing fastest and during 30th to 50th day population increases at lowest rate.
Explanation of Solution
Given:
The graph of number of flies and days is given as:
Concept used: Find the slope at different points to find the number of flies per day.
Calculation:
Let’s take the points
Apply the formula
Substitute
12 flies per day increasing between 15 to 25 days.
Let’s take the another points
Apply the formula
Substitute
5 flies per day increasing between 30 to 50 days which is slowest.
