The value of k would be 1. This is because the points (h, k) is the vertex and since k is the y-value of the vertex, we can see from the graph that it’s 1.
We know, equation of ellipse is given by :

Here,
(h,k) is centre of the ellipse = (0,0).
a = major axis = 8.
b = minor axis = 4.
Putting all given value in above equation, we get :

Hence, this is the required solution.

Answer:
Option c. integers from 1 to 10 inclusive.
Step-by-step explanation:
The given sets are A = { 1, 3, 5, 7, 9 }
B = { 2, 4, 6, 8, 10 }
C = { 1, 5, 6, 7, 9 }
We have to determine A ∪ B
A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Therefore, A ∪ B is the set of all from 1 to 10 inclusive.
option C will be the answer.
