Rewrite each fraction as an equivalent fraction and as a percentage.

1 answer:

7 0

5/20....an equivalent fraction would be 1/4...I simply reduces it. To find the percent, simply divide 1 by 4, which gives u 0.25.....and multiply that by 100 to give u ur percent...which is 25% (u multiply the decimal by 100 to get the percent)

9/25....since it will not reduce, multiply both numerator and denominator by the same number to get an equivalent fraction...9/25 * 2/2 = 18/50.
For the percent (u can use either fraction)....9/25...divide 9 by 25 and u get 0.36....multiply by 100 to get ur percent of 36%

9/6....reduces to 3/2.
3/2 = 1.5 = 150%

Solution:-

The standard sinusoidal waveform defined over the domain [ 0 , 2π ] is given as:

f ( x ) = sin ( w*x ± k ) ± b

Where,

w: The frequency of the cycle

k: The phase difference

b: The vertical shift of center line from origin

We are given that the function completes 2 cycles over the domain of [ 0 , 2π ]. The number of cycles of a sinusoidal wave is given by the frequency parameter ( w ).

We will plug in w = 2. No information is given regarding the phase difference ( k ) and the position of waveform from the origin. So we can set these parameters to zero. k = b = 0.

The resulting sinusoidal waveform can be expressed as:

f ( x ) = sin ( 2x ) ... Answer
