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?

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
