Which of the following statements about an ellipse is NOT true?
jeyben [28]

Answer: (b) The focus of an ellipse is always located precisely at the center of the ellipse.

Step-by-step explanation:

An ellipse is defined as <em>"a closed curve with two axes of symmetry (major axis and minor axis) that results in cutting the surface of a cone by an oblique plane to the axis of symmetry with an angle greater than that of the generatrix with respect to the axis of revolution"</em>. That is why the ellipse is considered a conic figure.

To understand it better: an ellipse has two points on its major axis that are equidistant from the center , which are called foci,  being this distance constant. In addition, the eccentricity allows to know how far the foci are from the center of the ellipse.

Therefore, the statement that indicates an ellipse has only one focus located  precisely at the center is incorrect.

Vinil7 [7]

Answer:

2.4 miles

Step-by-step explanation:

This is a simple ratio problem.

Penguins go 4/5 mile in 1/3rd hour. <em>So how many miles will they go in 1 hour? Let that be x:</em>

<em>\frac{\frac{4}{5}}{\frac{1}{3}}=\frac{x}{1}\\\frac{1}{3}x=\frac{4}{5}\\x=\frac{4}{5}*3=\frac{12}{5}</em>

<em />

<em>That is 12/5 miles or 2  2/5 miles</em>

<em>In decimal, that's </em><em>2.4 miles</em>
