Question 78

Multiple Choice

Which set of parametric equations represents the following line or conic?
Use x=h+asecθx = h + a \sec \theta and y=k+btanθy = k + b \tan \theta .
 Hyperbola:  vertices (10,1) ,(2,1)  foci (11,1) ,(3,1) \begin{array} { l l l } \text { Hyperbola: } & \text { vertices } & ( - 10 , - 1 ) , ( 2 , - 1 ) \\ & \text { foci } & ( - 11 , - 1 ) , ( 3 , - 1 ) \end{array}


A) x=4+13secθx = 4 + \sqrt { 13 } \sec \theta
y=1+6tanθy = 1 + 6 \tan \theta
B) x=4+13secθx = - 4 + \sqrt { 13 } \sec \theta
y=1+6tanθy = - 1 + 6 \tan \theta
C) x=1+13secθx = - 1 + \sqrt { 13 } \sec \theta
y=4+6tanθy = - 4 + 6 \tan \theta
x=4+6secθx = - 4 + 6 \sec \theta
D)
y=1+13tanθy = - 1 + \sqrt { 13 } \tan \theta
x=1+6secθx = - 1 + 6 \sec \theta
E) y=4+13tanθy = - 4 + \sqrt { 13 } \tan \theta
