From an elevation of 3.5m below the surface of the water, a northern bottle nose whale dives at a rate of 1.8m/s. write a rule that gives the whale’s depth d as a function of time in minutes. what is the whale’s depth after 4 minutes?

.

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.
