Answer 1

B) Least 10 hours, greatest 14 hours

Explanation:

The range of sin(x) is -1 ≤ sin(x) ≤ 1

Therefore, the range of
`\sin((\pi )/(6)t)` is
`-1\leq \sin((\pi )/(6)t)\leq 1`

Therefore, the range of
`2 \sin((\pi )/(6)t)` is
`-2\leq 2 \sin((\pi )/(6)t)\leq 2`

This means the range of
`2 \sin((\pi )/(6)t)+12` is
`10\leq 2 \sin((\pi )/(6)t)+12\leq 14`
