Q. What is the center of the ellipse 9x2+5y2−90=0?Write your answer in simplified, rationalized form.(______,______)
Divide by 90: Now, divide the entire equation by 90 to get the standard form of the ellipse equation. 10x2+18y2=1
Standard Form: The standard form of an ellipse is (x−h)2/a2+(y−k)2/b2=1, where (h,k) is the center.Here, we have x2/10+y2/18=1, which can be written as (x−0)2/10+(y−0)2/18=1.So, the center of the ellipse is (0,0).
