X^2/100+y^2/25=1 the length of the major axis is:

Step-by-step explanation:

x^2/100 + y^2/25=1 (1)

Since 25<100

Hence the above equation is of the form x^2/a^2+ y^2/b^2=1(2)

Comparing (1) and (2)

a^2=100

a=10

Major axis=2a=20

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
