Answer:


Step-by-step explanation:

e = 0.4142


Step-by-step explanation:


It is known that the sum of distance between a point on the ellipse and its focii is equal to 2 x a, where a is the length of the semi-major axis.  


Now, distance between the two foci is 2 x a x e = 2 units.  


And, the sum of the distance (S) between the foci and the point on the ellipse is:


S = 2 + (8)^(0.5)


Hence, we calculate e from the above two equations to be 0.4142.
