    Sorry forgot to post There are two fruit trees located at (3,0) and (–3, 0) in the backyard plan. Maurice wants to use these two fruit trees as the focal points for an elliptical flowerbed. Johanna wants to use these two fruit trees as the focal points for some hyperbolic flowerbeds. Create the location of two vertices on the y-axis. Show your work creating the equations for both the horizontal ellipse and the horizontal hyperbola. Include the graph of both equations and the focal points on the same coordinate plane. Maurice wants to use elliptical flower beds, so here is the equation: He has to use the equation --> a^2-b^2=c^2. C= 3 and I made a equal to 6. 6^2 - b^2 = 3^2. 36-b^2 = 9. b^2 = 27 b=5.196 --> x^2/a^2 + y^2/b^2 --> x^2/36 + y^2/27 = 1 Johanna wants to use hyperbolic flower bed, this is her equation: A will = 2 2^2+b^2=3^2 --> 4 + b^2 = 9 --> b^2 = 5 --> b = 2.236 x^2/a^2-y^2/b^2 = 1 --> x^2/2^2 - y^2 / 2.236^2 = 1
