So,

We see in Statement 3 that WY = WY. This seems obvious, but it ensures that quantities don't change their values. We call this property of something being equal to itself, the "reflexive property."

The correct answer is the third option.

Solve question 13. And 14. Please!! Will reward brainliest!!

Answer:

y = 4 sin( 0.5t - $\frac{4\pi }{3}$ ) - 2

y = a sin ( 2t - $\frac{-\pi }{3}$ ) + 2

Step-by-step explanation:

In the first question,

amplitude = 4

Period = $4\pi$

phase shift = $\frac{-4\pi }{3}$

Vertical shift = -2

Angular velocity , w = $\frac{2\pi }{time period}$

Here, w = $\frac{2\pi }{4\pi }$ = 0.5

The general equation of a wave is

y = a sin( wt + ∅ )

Putting above values in the equation,

y = 4 sin( 0.5t - $\frac{4\pi }{3}$ ) - 2

In the second question,

Amplitude is not given so we will take it as a.

time period = $\pi$

w = 2

Phase shift = $\frac{-\pi }{3}$

Vertical shift = 2

The equation is

y = a sin ( 2t - $\frac{-\pi }{3}$ ) + 2
