To graph: The points

Explanation of Solution
Given information:
The points,
Graph:
The plot the points
Construct a Cartesian plane with vertical axis as y-axis and horizontal axis as x-axis.
Marks the numbers on both the axes.
Plot the points
Interpretation:
The Cartesian plane is divided into four quadrant. Numbers on right of zero are positive, on left of zero are negative. Numbers above zero on vertical line are positive and numbers below 0 are negative. Each pair of point in the coordinate plane is represented as an ordered pair
To calculate: The distance between the pair of points

Answer to Problem 15E
The distance between the pair of points
Explanation of Solution
Given information:
The points
Formula used:
Distance
Calculation:
Consider the points
Recall that the distance
Evaluate the distance between
Thus, the distance between the pair of points is
To calculate: The midpoint of the segment that joins the pair of points

Answer to Problem 15E
The midpoint of the segment that joins the pair of points
Explanation of Solution
Given information:
The points are
Formula used:
Midpoint of the segment that joins two points
Calculation:
Consider the points
Recall that the midpoint of the segment that joins two points
Evaluate the midpoint of the segment that joins
Thus, the midpoint of the segment that joins the pair of points is

- Thumbi Irrigation Scheme in Mzimba district is under threat of flooding. In order to mitigate against the problem, authorities have decided to construct a flood protection bund (Dyke). Figure 1 is a cross section of a 300m long proposed dyke; together with its foundation (key). Survey data for the proposed site of the dyke are presented in Table 1. Table 2 provides swelling and shrinkage factors for the fill material that has been proposed. The dyke dimensions that are given are for a compacted fill. (1) Assume you are in the design office, use both the Simpson Rule and Trapezoidal Rule to compute the total volume of earthworks required. (Assume both the dyke and the key will use the same material). (2) If you are a Contractor, how many days will it take to finish hauling the computed earthworks using 3 tippers of 12m³ each? Make appropriate assumptions.
