And length of minor axis = 2b = 2*10 = 20. c) From part a) and b), we have a = 8 and b = 10 and h=3,k=-5 So, c2=b2-a2=102-82=100-64=36 =>c=sqrt36= 6. In this given equation b>a So, this is a vertical ellipse. Therefore, coordinates of foci = (3, -5+6) and (3, -5-6) Foci are (3,1) and (3, -11). d) This is the graph of given ellipse with foci and center. (12 points) Score | | 2.
