Provide an Appropriate Response $F ^ { \prime } ( - c , 0 )$

question 114

Multiple Choice

Provide an appropriate response.
-It can be shown that a hyperbola with center at the origin, foci at $F ^ { \prime } ( - c , 0 )$ and $F ( c , 0 )$ , and equation $d \left( P , F ^ { \prime } \right) - d ( P , F ) = 2 a$ has equation $\frac { x ^ { 2 } } { a ^ { 2 } } - \frac { y ^ { 2 } } { b ^ { 2 } } = 1$ . Use this result to find an equation of a hyperbola with center at the origin, foci at $( - 8,0 )$ and $( 8,0 )$ , and absolute value of the distances from any point of the hyperbola to the two foci equal to 8 .

• A) \(\frac { x ^ { 2 } } { 64 } - \frac { y ^ { 2 } } { 80 } = 1\)
• B) \(\frac { x ^ { 2 } } { 64 } - \frac { y ^ { 2 } } { 8 } = 1\)
• C) \(x ^ { 2 } - y ^ { 2 } = 8\)
• D) \(\frac { x ^ { 2 } } { 16 } - \frac { y ^ { 2 } } { 48 } = 1\)
