Q. Write the equation in standard form for the ellipse 7x2+y2=21.______
Identify equation and goal: Identify the given equation and the goal.The given equation is 7x2+y2=21, and we need to write it in standard form for an ellipse.
Recognize standard form: Recognize the standard form of an ellipse.The standard form of an ellipse is (a2x2)+(b2y2)=1, where a and b are the lengths of the semi-major and semi-minor axes, respectively.
Divide equation by 21: Divide the given equation by 21 to transform it into standard form.(7x2)/21+(y2)/21=21/21Simplify the equation:(x2/3)+(y2/21)=1
Verify equation in standard form: Verify that the equation is now in standard form.The equation (3x2)+(21y2)=1 is in the standard form of an ellipse, where a2=3 and b2=21.
