Question

The rise and fall of a radio transmitter on a buoy in the ocean is modeled by the function: y(t) 4.13sin(0.22t) +3.75 where y is feet above sea level and t is time in seconds. What real-world change would cause to change the model to the following? scientist y(t) 5 sin(0.15t) + 3.75 a) The waves are getting taller and closer together. b) The waves are getting shorter and farther apart. c) The waves are getting shorter and closer together. d) The waves are getting taller and farther apart e) None of the above

Answer 1

Correct option:

(a) The waves are getting taller and closer together

Explanation:
The multiplying factor is increased from 4.13 to 5. This indicates that the waves are getting taller.

$\theta$ is decreased from 0.22 to 0.15. This indicated that the waves are getting closer together.
