Absolute value is defined as follows:

|x| = x if x ≥ 0 and -x if x < 0.

To make an equation using absolute value, you need to look for the following:

1) something where you use positive and negative numbers

2) something where changing the sign between positive and negative, or vice versa, doesn't affect the problem.

Choice A talks about price per gallons. You can't have negative money amounts so this one won't work.

Choice B talks about distances of walking. In math classes you can have negative distance, but not in reality. Nope.

Choice D talks about books. But books sold as a negative number means you bought them, and the meaning changes. Nope.

Choice C uses "plus or minus". It also talks about something that's approximate, and it's also a case where the signs won't matter. Bingo.


Thus choice C is best.

What are the amplitude, period, and phase shift of the given function? f(t)=-1/2sin(3t-2pi)
Romashka [77]

Answer:

The amplitude=|A|=\frac{1}{2}, period=3 and \text{phase shift}=\frac{2\pi}{3}.

Step-by-step explanation:

The given function is

f(t)=-\frac{1}{2}\sin (3t-2\pi)      .... (1)

The general form of sine function is

F(t)=A\sin (Bt-C)+D                 ....(2)

where, |A| is the amplitude, B is period, D is the vertical shift (up or down), and C/B is used to find the phase shift.

On comparing (1) and (2), we get

A=-\frac{1}{2}

B=3

C=2\pi

D=0

So,

amplitude=|A|=\frac{1}{2}

period=3

\text{phase shift}=\frac{2\pi}{3}

Therefore amplitude=|A|=\frac{1}{2}, period=3 and \text{phase shift}=\frac{2\pi}{3}.
