Answer:
[tex]y(t) = 750 -50t[/tex]
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:
[tex]y(t) = 750 -50t[/tex]
Answer:
im pretty sure it's -750 + 4 x 50
Step-by-step explanation:
This is the only answer that really makes sense to me
