Find the center and the foci of the ellipse given by the equation -y^2+10y-4=9x^2+12x. At what points, if any, does this ellipse intersect the line
This equation may be rewritten as:
9x2 + Y2+ 12X -10Y +4=0
to find the center we have
h= 12/2*9 = (2/3) = Coefficient...
520.2 x 25
13005 if the 520 are millions we will have that the answer will be
First we need to define the center that in this case is located at (6-4)/2 = 5=k the center will be at
(3,5). The major axis is parallel to the y axis as we may see for the development of the vertices which move only parallel to the y axis.
Then we have to calculate a, b, c
a is the...
