Question

find the focus and directrix of the parabola 4y2 +12x -12y +39​

Answer 1

Step-by-step explanation:

Find vertex, focus, direction, and graph parabola given x^2 + 12x - y + 39 = 0 Given x^2 + 2y^2 - 6x + 4y + 7 = 0, find vertices and foci & graph the ellipse Given 16x^2 - 9y^2 + 64x - 90y = 305; find vertices, foci, asymptotes and graph the hyperbola Find equation of parabola wf focus (0, 6) and directrix (0, plusminus 2) Find equation of ellipse that shares a vertex and focus with the parabola x^2 + y = 100 & the other focus is at the origin. Sketch x = t^2 + 4t -4t lessthanorequalto t lessthanorequalto 1. Eliminate the parameter "t" to find the Cartesian equation Find that equation of the tangent line to the curve given x = ln t y = 1 + t^2 t = 1 Find dy/dx and d^2y/dx^2 given x = t cos t y = t sin t
