It is helpful to find a unit rate first. If you find a unit rate first, then it will be easier to compare
Answer:
The correct option is;
f(x) = 3·sin x/8·π + 2
Step-by-step explanation:
The given parameters for the sinusoidal function are;
Amplitude of oscillation = 3
Frequency of oscillation = 1/8·π
Midline of oscillation= 2
The general form of sinusoidal equation is y = A·sin(B(x - C)) + D
Where;
A = The amplitude
B = The frequency
C = The horizontal shift
D = The midline or vertical shift
Substituting the given values into the general form of sinusoidal equation, we have;
f(x) = y = 3·sin(1/8·π(x - 0)) + 2 = 3·sin(x/8·π) + 2
Which gives;
f(x) = 3·sin(x/8·π) + 2.
Answer:
1.97
Step-by-step explanation:
The null hypothesis is:

The alternate hypotesis is:

Our test statistic is:

In which X is the sample mean,
is the hypothesis tested(null hypothesis),
is the standard deviation and n is the size of the sample.
In this problem, we have that:

So



Answer:
x = 28
Step-by-step explanation:
The ratios of corresponding sides are equal, that is
=
( cross- multiply )
8(x - 7) = 168 ( divide both sides by 8 )
x - 7 = 21 ( add 7 to both sides )
x = 28
