Answer:
.
435.5 meters below water surface.
Step-by-step explanation:
We have been given that from an elevation of 3.5 m below the surface of the water. A northern bottle nose whale dives at a rate of 1.8 m/s.
Let us convert whale's dive rate in terms of meters per minute.
Since we know that 1 minute=60 seconds so we will multiply whale's dive rate by 60 to convert it in meters per minute.
We can write a rule that gives the whale's depth d as a function of time in minutes as:
Therefore, our function will be .
Now let us find whale's depth after 4 minutes by substituting t=4 in our function.
Therefore, after 4 minutes whale will be 435.5 meters below water surface.
