Suppose that the foci of the ellipse x^2/9 + y^2/5 =1 are (f1, 0) and (f2, 0) where fi> 0 and f2<0. Let P1 and P2 be two parabolas with a common vertex at (0, 0) and with foci at (fi, 0) and (2f2, 0), respectively. Let T be a tangent to P, which passes through (22, 0) and 7 be a tangent to P, which passes through (fi, 0). The m 1 is the slope of T and m is the slope of T, then the value of +1 m Suppose that the foci of the ellipse x^2/9 + y^2/5 =1 are (f1, 0) and (f2, 0) where fi> 0 and f2<0.
