You can use the Pythagorean theorem for this problem.
a^2 + b^2 = c^2
a^2 + 5^2 = 10^2
a^2 + 25 = 100
a^2 = 75
a = 8.66

h = 8.7

Hope this helps =)

A plot of land in the shape of a vertical ellipse has a pole at each focus. The foci are 8 feet from the center. If the plot of
PtichkaEL [24]

Answer:

1. B

2.C

Step-by-step explanation:

A plot of land in the shape of a vertical ellipse. The equation of the ellipse is

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1.

If the foci are 8 feet from the center, then c=8.

If the plot of land is 34 feet across the vertical axis, then 2b=34\Rightarrow b=17.

Use formula c=\sqrt{b^2-a^2} (because ellipse is vertical, then b>a) to find a:

8=\sqrt{17^2-a^2}\Rightarrow a^2=289-64=225,\ a=15.

Then  the plot of land is 2a=30 ft across the other axis.

If b>a, the eccentricity of the ellipse is

e=\dfrac{c}{b}=\dfrac{8}{17}\approx 0.471.
