Question 307008: I cannot figure this out it's stressing me out.....I hope u can help me. PLEASE
16y^2-9x^2+36x-32y-164=0 I need to know the coordinates, and if its hyperbolic(center and focci) circular (center and vertex) elliptical(center and focci) parabolic(vertex and focus). Please please explain. Thank you

Question 308473: identify the conic defined by each equation. If it is a parabola, give its vertex, focus, and directrix; if an ellipse, give its center, vertices, and foci; if a hyperbola, give its center, vertices, foci and asymptotes. Draw a graph with these features identified.
8y = (x −1)^2 − 4
I think this is a parabola I am not sure. Once I know what type of conic the equations are then I know how to solve then I just have trouble determining the difference between the three.
My second question is this second equation. I think this one is an ellipse but I just want to be sure.
2x^2 + 3y^2 + 4x − 6y =13
My third question is this third equation which I think is an hyperbola.
(x+1)^2/4-y^2/9=1
My fourth question of the day is....
A parabolic reflector (paraboloid of revolution) is used by TV crews of a football game to pick up
the referee’s announcements, quarterback signals, and so on. A microphone is placed at the focus
of the parabola. If a certain reflector is 4 feet wide and 1.5 feet deep, where would the microphone
be placed? Include a well labeled sketch with your answer.

Question 308992: 4x^2 + ky^2 - 8x + 17y = 3
Find the vaule of k to make this equation a circle, ellipse, hyperbola, and parabola; so different vaules for k that will make those different kinds of equations.
Any single one of them would be helpful if you can't necessairly figure them all out, so if you know anything at all pleaseee help. Thank you so much!

Question 309219: Write an equation for the hyperbola...I have no idea.
vertices (0,6) and (0,-6) conjugate axis of 14.
I'd really like to figure out on my own but I have no idea where to start..so if someone could give me a step-by-step solution, that would be wonderful! Thank you.
