4 a dragonfish is swimming at -900 m relative to sea level. it rises 250 m. what is the dragonfish’s new depth relative to sea level? show your work.

Explanation:

Step1: Understand the initial depth

The dragonfish starts at a depth of \(-900\) m (negative because it's below sea level).

Step2: Calculate the new depth after rising

When it rises \(250\) m, we subtract the rise from the initial depth (since rising means moving towards sea level, which is a less negative or positive direction). So we do \(-900 + 250\).
To calculate this, we know that \(900 - 250 = 650\), and since we are adding a positive number to a negative number, the result is \(-650\) m.

Answer:

The dragonfish's new depth relative to sea level is \(-650\) m.
