Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels.

Answer 2

Explanation:

α,β are the zeroes of x2−(k+6)x+2(2k−1)

i.e, α+β=k+6 ( Sum of roots of quadratic )

and αβ=2(2k−1) ( Product of roots )

According to question, α+β=21αβ

⇒k+6=22(2k−1)=2k−1

⇒k+6=2k−1

⇒k=7

Hence, the answer is 7.
