for a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2pit/t , where a is the amplitude and t is the period of the wave in seconds.
13.  how many times over the first 5 seconds does the graph predict the wave to be 2 feet high?
(show work)

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
