a.
To verify survey based data.
a.
Answer to Problem 90E
The graph shows the
Explanation of Solution
Given information:
From the top of a mountain road, a surveyor takes several horizontal measurements
Sketch a scatter plot of the data.
Calculation:
Scatter plot of the data given in table,
Hence the graph shows the scatter plot of data.
b.
To verify survey based data.
b.
Answer to Problem 90E
The graph shows a straightedge.
Explanation of Solution
Given information:
From the top of a mountain road, a surveyor takes several horizontal measurements
Use a straightedge to sketch the line that you think well fits the data.
Calculation:
Scatter plot of the data given in table,
Hence the graph shows a straightedge.
c.
To verify survey based data.
c.
Answer to Problem 90E
Explanation of Solution
Given information:
From the top of a mountain road, a surveyor takes several horizontal measurements
Find an equation for the line you sketched in part
Calculation:
The slope
Now find slope
Now, with the use of point
Now multiply both side of equation by
Now subtract
Hence equation of line is obtained
d.
To verify survey based data.
d.

Interpret the meaning of the slope of the line in part
Calculation:
According the results in part
e.
To verify survey based data.
e.
Answer to Problem 90E
The sign state for the road with a downhill grade that has a slope of
Explanation of Solution
Given information:
From the top of a mountain road, a surveyor takes several horizontal measurements
The surveyor needs to put up a road sign that indicates the steepness of the road. For instance, a surveyor would put up a sign that states “
Calculation:
The sign state for the road with a downhill grade that has a slope of
