average amplitude of waves from 2009 to 2011\n\na structural engineer is using this table to design a wall to protect a city near the ocean.\nhow high should the engineer build the wall?\n\n50 meters\n100 meters\n150 meters\n200 meters

Answer

Explanation:

Step1: Identify the maximum wave amplitude

Observe the peak of the line graph between 2009 and 2012. $$A_{max} = 175 \text{ meters}$$

Step2: Determine the required wall height

The wall must exceed the maximum recorded amplitude to provide protection. $$H_{wall} > 175 \text{ meters}$$

Step3: Select the appropriate option

Choose the smallest provided value that is greater than the peak amplitude. $$200 \text{ meters} > 175 \text{ meters}$$

Answer:

200 meters
