Answer:
The height of the barnacle is approximately is, 0.657 meters.
Step-by-step explanation:
Given the graph below of y =sin(x) ......[1]
Let y be the height of the barnacle and x be the distance the boat has traveled
Given: The boat has traveled 7 meters
i.e, x = 7 meters
to find the height y :
Substitute the value of x =7 meters in [1] we have;
y = sin(7) ≈0.657.
Therefore, the height of the barnacle is approximately is, 0.657 meters.

The inequality is
Step-by-step explanation:
Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.
To find : Which inequality represents this situation?
Solution : He plays trumpet for a minimum of 45 minutes
If x is the number of days that Lionel practices then he practices for at least
hours
y is the total number of hours he spends practicing
So, the inequality form is:
i.e, 0.75x is greater than y.
