Question

Plot the points A(-5, -2), B(1, -2), C(6, 4) and D(0,4). Join the points to get AB, BC, CD & DA. Name the
figure so obtained

Answer 1

Answer:

Slope is the change in elevation over a certain distance: Slope is defined as the change in elevation over a horizontal distance. That is: slope elevation-change/ distance Ignore the sign (+/-) of the slope and just use the slope's absolute value. Both the elevation-change and distance MUST be in units of feet. At the top of the map is a east-west trending blue dotted line with text labels A,B,C,D.E to be used to answer the following questions. Note that there are 50 feet between the bold brown contour lines. Question 5 1 pts Measure the distance and elevation change between points A and B. Then, calculate the slope along line segment A-B and enter the value. 0.011 Question 6 1 pts Measure the distance and elevation change between points B and C. Then, calculate the slope along line segment B-C and enter the value. 0.059 Question 7 1 pts Measure the distance and elevation change between points C and D. Then, calculate the slope along line segment C-D and enter the value. 0.013 Question 8 1 pts Measure the distance and elevation change between points D and E. Then, calculate the slope along line segment D-E and enter the value. 0.18 Question 9 1 pts For line A-E, plot the elevation and distance between each point A, B, C, D, and E on this graph paper here and then uploaded a legible camera show of your graph to answer this question. This will create a "topographic profile of the hill along line A-E, also known as a cross-sectional view. Notice that the scale for elevation is not the same as the scale for distance on this graph. The graph has "vertical exaggeration" so you can more easily see the changes in slope.
