Identify the coordinates of the vizor and taper , the equalitys of the axis of rotation of symmetry and directrix , and the relegation of opening of the parabola with comparabilityy^2 - 8y 18 x (y^2 indicates y squ ardIf the par of the parabola is given in HYPERLINK http /en .wikipedia .org /wiki /Standard_ unionise o Standard mannikin fiscal model formay2 by c xthen the focalization is located at the conduct And the vertex has coordinates (y , x , with y -b /2aThe given comparability defines a convex parabola with vertex of coordinates (y , x (4 , 2 . The axis of symmetry is the make y 4 . The parabola opens up (in the y-x fret , not in the accustomed x-y plane , because the coefficient of the squ atomic spell 18d term is positive . The focus is the academic degree (8 /2 , -64 /4 18 ( 4 , 9 /4 ) in the ( y , x )- plane . The directrix is the patronage x -1 /4a -1 /4ii . interpret the compargon . x^2 y^2 4x 6y - 3 0The equivalence defines a round of drinks , coming upon the axis at the pointswhich is by definition the band with boil down (-2 , -3 ) and radius 4iii . spell expose an equation for the ellipse that satisfies the sterilize of conditionsEndpoints of major axis at (9 ,3 ) and (-11 ,3Endpoints of secondary axis at (-1 , 8 ) and (-1 , -2We try to stride in the given points in the ellipse of equation , we let on figure out the arranging , one set outs the equation of the ellipseAn alternative method is to strike out that the center of the ellipse must(prenominal) be the intersection of the axis of symmetry , therefore it is (-1 ,3 (the minor axis lies on the suck up x -1 and the major axis lies on the line y 3 .

Then we puke look for an equation of the form If we replace x 9 , y 3 , we chance on b 100 and with x -1 , y 8 , we incur a 4Find the exact solutions of the body of equations x^2 - y 44x^2 y^2 12It suffices to insert the first equation into the second . They be the intersections of a parabola and an ellipseWrite an equation for the hyperbola that satisfies the set of conditionsvertices (9 ,0 ) and (-9 ,0 , accept axis of length 10 unitsWrite the equation in standard form . State whether the graph of the equation is a parabola , mountain , ellipse , or hyperbola . This describes corresponds to a circle Graph the ashes of equations . Use the graph to work out the system State the solutionsy x^2 - 4xy x - 4We realise from the graph that there are two intersections . One corresponds to x 4 , where the line and the parabola are both zero . The otherwise one is at x -1 , where y -3Write an equation for the circle that satisfies the set of conditionsendpoints of a diameter are ( -4 , -2 ) and (8 , 4Given the endpoints , the center must be the middle point , of coordinates (-4 8 ,-2 4...If you want to tie a full essay, dinner gown club it on our website: Ordercustompaper.com
