<h3>
Answer:</h3>
For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin \frac{2\pi t }{T} , where a is the amplitude and T is the period of the wave in seconds.
Write an equation for the given function given the amplitude, period, phase shift, and vertical shift.
<u><em>Add something</em></u>
amplitude: 4, period = 4^{\pi } phase shift = -\frac{4}{3}\pi vertical shift = -2

Answer:
Step-by-step explanation:
By the geometric mean theorem,
So, by the Pythagorean theorem,
The length, we'll call it <em>l</em> is 2 meters less than the height, which we'll call <em>h</em>. The expression that will model this problem is <em>h-2</em><em>, </em>or as an equation, <em>l=h-2</em><em />.

Answer:
<h2>0i</h2>
Step-by-step explanation:
The imaginary number has form:
<em>a + bi</em>
<em>a</em><em> - real part</em>
<em>bi</em><em> - imaginary part</em>
<em>i</em><em> - imaginary unit (i = √-1)</em>
We have the number 9.
<em>9</em><em> is a real part</em>
An imaginary part is equal 0.
Therefore the imaginary part of number 9 is 0i.
