Mathematics

Answer:

Maximum: 1, Minimum: -3, Midline y = -1, Amplitude = 4, Period = \pi, Frequency \displaystyle =\frac{1}{\pi},  equation : f(x)=-4cos(2x)+1

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:

\displaystyle y=\frac{1-3}{2}=-1

Amplitude is the difference between the maximum and minimum values

A=1-(-3)=4

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 x=\pi

Thus the period is

T=\pi

The frequency is the reciprocal of the period:

\displaystyle f=\frac{1}{T}=\frac{1}{\pi}

The angular frequency is

\displaystyle w=2\pi f=\frac{2\pi }{\pi}=2

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:

f(x)=-4cos(2x)+1

Rohan did a survey in four bird parks and wrote the following observations:
stiks02 [169]

Answer:  Park P

Step-by-step explanation:

Since, According to the question,

Number of yellow bird in park P = 33

Total number of the bird in park P = 53

Thus, the percentage of yellow bird in park P = \frac{33}{53} \times 100= 62.264150943% ≈ 62 %

Number of yellow bird in park Q = 20

Total number of the bird in park Q = 48

Thus, the percentage of yellow bird in park P = \frac{20}{48} \times 100=41.666666666% ≈ 42%

Number of yellow bird in park R = 54

Total number of the bird in park R = 90

Thus, the percentage of yellow bird in park R = \frac{54}{90} \times 100= 60 %

Number of yellow bird in park S = 44

Total number of the bird in park S = 83

Thus, the percentage of yellow bird in park P = \frac{44}{83} \times 100=53.012048192 % ≈ 53 %

Since, 62% > 60% > 53% > 42%

Therefore, highest percentage of the yellow bird is 62 %

Which is present in park P.
