Which list shows the in greatest to least?<br><br>(NEED ASAP)
NeX [460]

The answer is B.

\frac{14}{5} = \frac{28}{10}

\frac{5}{2} = \frac{25}{10}

1\frac{3}{10} = \frac{13}{10}

\frac{3}{5} = \frac{6}{10}

If you find a common denominator, the process becomes much easier. I hope this was helpful.

Which lines are the directrices of the ellipse?
algol [13]

The lines that are the directrices of the ellipse is B. x = −3.25 and x = 9.25.

<h3>How to calculate the ellipse? </h3>

From the information given, the equation of parabola will be:

= (x - 3)²/5² + (y - 2)²/3² = 1

Hence, h = 3, k = 2, a = 5, b = 3

e = ✓1 - ✓3²/5²

E = 4/5 = 0.8

The directix will be:

x = 3 + 5/0.8

x = 9.25

x = 3 - 5/0.8

x = -3.25

Therefore, lines that are the directrices of the ellipse is x = −3.25 and x = 9.25.
