Solution
1. The algebraic expression = -0.5n - 3.8, where n is the number of minutes.
2. Here the variable "n" represents the number of minutes.
Thank you.
For this case we have the following data:
- 3.8 is the distance below the surface of the water
- 0.5 is the rate of descent, given in meters per minute
In this way, the depth of the diver for a certain number of minutes is given by:
, where x represents the number of minutes
Answer:
