Step-by-step explanation:
<u>Sinusoid Functions</u>
It refers to the oscillating functions like the sine or cosine which range from a minimum and maximum value periodically.
The graph shown can give us all the information we need to answer these questions:
Maximum: 1
Minimum: -3
The midline goes through the center value (mean) of the max and min values, i.e.
Equation of the midline:

Amplitude is the difference between the maximum and minimum values

The period is the time it takes to complete a cycle. We can see the minimum value is first reached at x=0 and next at 
Thus the period is

The frequency is the reciprocal of the period:

The angular frequency is

The equation of the function is a negative cosine (since it starts at the minimum) or a shifted sine or cosine. We'll choose the negative cosine, knowing all the parameters:

Answer:
no because at the end it is 669 not 696 so it is not repeating decimal
Answer:
The value of the given expression is 84.
Step-by-step explanation:
The given expression is

The number 252 can be written as 240+12, because 24 can easily divisible by 3.
The compatible numbers are 240 and 12




Therefore the value of the given expression is 84.
