Determine the Two Equations Necessary to Graph the Ellipse with a Graphing

Question 74

Multiple Choice

Determine the two equations necessary to graph the ellipse with a graphing calculator.
- x216+(y5) 225=1\frac { x ^ { 2 } } { 16 } + \frac { ( y - 5 ) ^ { 2 } } { 25 } = 1


A) y=20516x24y = \frac { 20 - 5 \sqrt { 16 - x ^ { 2 } } } { 4 } and y=516x2+204y = \frac { 5 \sqrt { 16 - x ^ { 2 } } + 20 } { 4 }
B) y=540025x220y = \frac { 5 \sqrt { 400 - 25 x ^ { 2 } } } { 20 } and y=540025x220y = - \frac { 5 \sqrt { 400 - 25 x ^ { 2 } } } { 20 }
C) y=40025x24y = \frac { \sqrt { 400 - 25 x ^ { 2 } } } { 4 } and y=40025x24y = - \frac { \sqrt { 400 - 25 x ^ { 2 } } } { 4 }
D) y=80025x24y = \frac { \sqrt { 800 - 25 x ^ { 2 } } } { 4 } and y=80025x24y = - \frac { \sqrt { 800 - 25 x ^ { 2 } } } { 4 }
