a.
Represent annual sales with the slopes of lines.
a.
Answer to Problem 88E
Explanation of Solution
Given information:
The graph shows the sales (in billions of dollars) for Apple Inc. in the years
Use the slopes of the line segments to determine the years in which the sales showed the greatest increase and the least increase.
Calculation:
Consider The graph shows the sales (in billions of dollars) for Apple Inc. in the years
The slope
Now consider each point given in the graph,
Slope between points
Slope between points
Slope between points
Slope between points
Slope between points
Slope between points
Hence for years
sales has greatest increase
b.
Represent annual sales with the slopes of lines.
b.
Answer to Problem 88E
Slope of line connecting the points for year
Explanation of Solution
Given information:
The graph shows the sales (in billions of dollars) for Apple Inc. in the years
Find the slope of the line segment connecting the points for the years
Calculation:
Consider The graph shows the sales (in billions of dollars) for Apple Inc. in the years
The slope
Slope of line connecting the points
Hence Slope of line connecting the points for year
c.
Represent annual sales with the slopes of lines.
c.
