Answer:
The equation of ellipse is [tex]\frac{x^2}{9}+\frac{y^2}{16}=1[/tex].
Step-by-step explanation:
Consider the provided information.
The rectangular piece of property measures 8 mi by 6 mi.
It is a vertical ellipse.
So, use the equation: [tex]\frac{x^2}{b^2}+\frac{y^2}{a^2}=1[/tex]
Where the value of a and b are:
[tex]a=\frac{8}{2}=4\\b=\frac{6}{2}=3[/tex]
The major axis is along y-axis with the vertices (0,4) and (0,-4).
The minor axis is along the x-axis, with the vertices (-3,0) and (3,0).
Now substitute the value of a and b in [tex]\frac{x^2}{b^2}+\frac{y^2}{a^2}=1[/tex]
[tex]\frac{x^2}{3^2}+\frac{y^2}{4^2}=1[/tex]
[tex]\frac{x^2}{9}+\frac{y^2}{16}=1[/tex]
Hence, the equation of ellipse is [tex]\frac{x^2}{9}+\frac{y^2}{16}=1[/tex].
