Write an equation in standard form for the parabola that open to the left, has its vertex at (0,2) and goes through the point (-6,-4) ( - )2 = The focus of y2 = 12x is Write the coordinate, for example (2,1) The ellipse (x2/25) + (y2/4) = 1 and the hyperbola (x2/4) - (y2/25) = 1 intersect each other at 4 points. Find the coordinates of those points. (++) (-+) Round the answer to two decimal places (+-) (--) Vertices Center Given the hyperbola ( x + 2 )2 ( y - 5)2 Write in coordinate form for example (-1,2) Find 9 from left to right - and 49 = 1 The parabola has the vertex at the origin and the directrix x = 1 . What is the equation of the parabola? x2 = 4y x2 = -4y y2 = x x2 = (1/4)y y2 = -4x Find an equation for the hyperbola with vertices at (–2, 15) and (–2, –1), and having eccentricity e = 17/8. ( )2 ( )2 = 1 The center of 4x2 - 12y2 - 16x - 72y - 44 = 0 is: A Which one is the graph for the following equation? B C Identify the conic of the equation below 10y2 - 20x2 + 60y +160x - 255 =0 Hyperbola Ellipse Circle Parabola A bridge over a river is supported by a single semielliptical arch. The river is 50 feet wide. At the center, the arch rises 20 feet above the river. The roadway is 4 feet above the center of the arch. What is the vertical distance between the roadway and the arch 15 feet from the center? feet An ellipse with the major axis of 10 meter long and the minor axis of 8 meter long. Find the value of its eccentricity What the is the equation of the graph below? C B A D Find the eccentricity of the curve: C A D B The radius of the circle passing through the point (5,2), (5,-2) and (1,2) is B A D C The circle x2 + y2 + 6x - 6y + 9 =0 touches the x - axis touches the y - axis passes through the origin touches both axes The circle x2 + y2 + 6x - 6y + 9 =0 has its center at write the answer as the coordinate of a point, for example (1,2) |
