What are the following of this function y = 4sin (2( x - <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%20%7D%7B4%7D" id="Te

Andrei [34K]

Answer:

See below...

Step-by-step explanation:

For a function whose formula is in this pattern:

$y=A\sin\left(B(x-C)\right)$

Amplitude: $|A|$

Period: $\frac{2\pi}{B}$

Phase Shift: C

In this question, $A=4,\,B=2,\,C=\frac{3\pi}{4}$

Amplitude: 4

Period: $\frac{2\pi}{2}=\pi$

Phase Shift: $\frac{3\pi}{4}$

There is no vertical shift, so the midline is the x-axis whose equation is y = 0.

Also, because there is no vertical shift, the maximum is 4 and the minimum is -4.

The graph is attached.

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 196 feet, and ball 2 is droppe

Anon25 [30]

H1 (t) = 196 - 16 t-squared. / / / H2 (t) = 271-16t-squared. / / / In each function, 't' is the number of seconds after that ball is dropped. / / / Each function is only true until the first time that H=0, that is, until the first bounce. Each function becomes very complicated after that, and we would need more information in order to write it.

Answer:

It is equal to each other

Step-by-step explanation:

$\sqrt{\frac{1}{x^2}} = \frac{1}{x}\\\sqrt[3]{\frac{1}{x^3}} = \frac{1}{x}$
