First you’d separate into 2 inequalities so it would change to t-4/-3>-2 then you’d solve it for inequalities t-4/-3>-2 then you’d find the intersection which would be the answer: T (3,10)

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

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