Question 82 • AZ-Common Core Algebra II B
Check each of the following that you included in your explanation.
Answer
A
When the graph is below the x-axis, the barnacle is underwater.B
The graph dips below the x-axis three times between x = 0 and x = 20, so the barnacle goes underwater three times.C
Every time the barnacle goes underwater, the boat travels [image 1] meters (one half the circumference of the wheel) before the barnacle comes back up, so the barnacle covers 3 [image 2] meters underwater between x = 0 and x = 20.
