Step-by-step explanation: A triangle is 180 degrees, always. One angle is 60 and the other above is 90. We add them together and get 150. Subtract it from 180 and we get 30 degrees.

P.S.: I'm sorry that I put only w, that's the only one I could work out . Also sorry if I'm wrong, maths is not my very strong subject.

Write a sine function that has a midline of 5, an amplitude of 4 and a period of 3pi/2

soldi70 [24.7K]

Answer:

Step-by-step explanation:

The standard form for this function is

y = Asin(Bx - C) + D where

A is the amplitude,

B is used to find the period in the formula $period=\frac{2\pi}{B}$ ,

C is used to find the phase shift in the formula $ps=\frac{C}{B}$ ,

and D is the midline which either moves the function up or down from its natural midline of 0.

We have no given phase shift, so there is no C value. The amplitude is easy; we just fill in A as 4. The period is another story:

$\frac{3\pi}{2} =\frac{2\pi}{B}$ and we solve for B by cross multiplying:

3πB = 4π and

$B=\frac{4\pi}{3\pi}$ so

$B = \frac{4}{3}$ so the function is

$y=4sin(\frac{4}{3}x)+5$
