Question

graph the ellipses, state the focal points of each ellipse. equation: (x-5)^2/25 + (y-2)^2/4=1

Answer 1

the center: (5,2)
c^2= 5^2 -2^2=√21
foci at:(5 ∓ √21 , 2)
The lenghth of the major axis is : 5(2) = 10
The lenghth of the minor axis is : 2(2) = 4
x^2 greater denominator: the major axis is horizontal.
