Find an equation of the ellipse with foci at (−4,3) and (−4,−9)
and whose major axis has length 30. Express your answer in the form
P(x,y)=0, where P(x,y) is a polynomial in x and y such that the
coefficient of x^2 is 225.
Find the equation of the ellipse with foci at (0, 0) and (2, 2),
with eccentricity e = 0.5. Express the equation in standard form
ax2 + by2 + cxy + dx + ey = f and in terms of the distance formula
sqrt(x^2+y^2) + sqrt[(x-2)^2 +(y-2)^2]=?
There is an answer posted on Chegg, but I don't think I agree
with it. Since the foci are at (0, 0) and (2, 2) it seems that the
major axis is rotated...
find the coordinates of the center and foci and the lengths of
the major and minor axes for the ellipse with the given equation.
remember to complete the square in oder to accuartely graph the
ellipse: 9x^2+6y^2-36x+12y=12
Find the equation of the hyperbola with:
(a) Foci (1, −3) and (1, 5) and one vertex (1, −1).
(b) Vertices (2, −1) and (2, 3), and asymptote x = 2y.
Consider the set of points described by the equation 16x2 −4y2
−64x−24y+19=0.
(a) Show that the given equation describes a hyperbola and find
the center of the hyperbola.
(b) Determine the equations of the directrices as well as the
eccentricity.
1. Find the standard form of the equation of the hyperbola
satisfying the given conditions. Foci at (-5,0) and (5,0); vertices
at (1,0) and (-1,0).
2. Find the standard form of the equation of the hyperbola
satisfying the given conditions. Foci at (0,-8) and (0,8); vertices
at (0,2) and (0,-2).
An equation of an ellipse is given. 2x^2 + 64y^2 = 128 (a) Find
the vertices, foci, and eccentricity of the ellipse. vertex(x, y)=
(smaller x-value) vertex(x, y)= (larger x-value) focus(x, y)=
(smaller x value) focu (x, y)= (larger x-value) eccentricity (b)
Determine the length of the major axis. Determine the length of the
minor axis. (c) Sketch a graph of the ellipse.
For the ellipse 6? 2 + 4? 2 = 36, find the eccentricity and
sketch the graph showing all main features including axis
intercepts, foci and directrices.
b) Using exclusively some part of your answer to part a),
determine the foci and directrices for the curve: (? + 2) 2 6 + (?
