The equation 4x^2+9y^2-36y = 0 defines a shifted ellipse. Write this equation in the standard form, find the center, focus, vertices of this ellipse, the lengths of major and minor axes and sketch...

What is the standard form equation of a hyperbola with vertices at (0, 2) and (-10, 2) and foci at (8, 2) and (-18, 2)? standard form equation of a hyperbola.

identify the vertex and axis of symmetry of each then sketch the graph.

Write equation in standard form. Cirles, identify the center and radius. Identify ellipses and hyperbole identify the center.

Y2-8x+10y+9=0

Identify this equation without completing the square. x2 + y2 - 8x + 4y = 0 The equation defines a circle. The equation defines an ellipse. The equation defines a hyperbola...

a math question from my math homework

I how do I write the vertex form of a parabola given the vertex and the focus. Example: Vertex (-3,4) Focus (-23/8,4)

such as hyperbola, ellipse, or parabolas?

Select the x-coordinate of the vertex of the parabola defined by the function f(x) = -3x2 + 7x + 9.

Tricky Question: Find an equation that models the path of a satellite if its path is a hyperbola, a= 55,000 km, and c= 81,000 km. Assume that the center of the hyperbola is the origin...

I messed up typing it in last time this should work but im not sure.
