To find: The vertices, foci and the length of the major and minor axis of the ellipse

Answer to Problem 2T
The focus of the ellipse
The vertices of the ellipse
The length of major axis in the ellipse
The length of minor axis in the ellipse
Explanation of Solution
Definition used:
“The equation of the ellipse center at the origin with vertices
The given equation is in standard form of the ellipse
Therefore, compare the equation Use online graphing calculator and obtain the graph of
with the equation of ellipse
So , clearly the value of
Compute the value of
Therefore, the value of
Compute the value of
Therefore, the value of
Compute the value of
Therefore, the value of
From by the definition stated above, the focus and vertices of the ellipse are
Therefore, the focus and vertices of the ellipse
The length of major axis in the ellipse
The length of minor axis in the ellipse
Use online graphing calculator and obtain the graph of
From figure 1, observed that the focus and vertices of the ellipse

- 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?
