Answer:
![y(t) = 750 -50t](https://tex.z-dn.net/?f=y%28t%29%20%3D%20750%20-50t)
Step-by-step explanation:
We want to model the position of the submarine as a function of time.
Notice that we have a constant amount. The initial depth: 750 meters
Then we have a factor that varies over time. Every hour the submarine ascends 50 meters. therefore as t increases the depth y(t) of the submarine decreases. Then the factor is:
-50t.
Where t represents the time in hours.
Then the equation that represents the new position of the submarine in relation to the level of the sea:
![y(t) = 750 -50t](https://tex.z-dn.net/?f=y%28t%29%20%3D%20750%20-50t)
