Write the equation of the ellipse with center (4,2), vertex (9,2), and focus (4+2sqrt5,2)

Answer : option B

Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)

The distance between vertex and center is 9-4 = 5

Center is (h,k) so h= 4  and k =2

focus is (h+c,k)

From the given focus (4+2sqrt5,2), c= 2sqrt(5)

Standard form of equation is

h= 4, k=2, a=5, c=2sqrt(5), we need to find out b

b^2 = 5

plug in all the values

Option B is correct

17.08

correct me if i am wrong.

22.83 repeating

step-by-step explanation:
