Answer

y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49

Step by Step Explanation

Given

See attachment for table

Required

Determine the sinusoidal function

The sinusoidal function is represented as:

y = A \sin(Bx + C) + D

Where

|A| = Amplitude

And it is calculated as:

A = \frac{1}{2}[Highest - Least]

From the table:

Highest = 77 and Least = 21

So:

A = \frac{1}{2}[77 - 21]

A = \frac{1}{2}[56]

A = 28

B is calculated as:

Period = \frac{2\pi}{B}

The period is 12 i.e. 12 months

So:

\frac{2\pi}{B} = 12

B = \frac{2\pi}{12}

B = \frac{\pi}{6}

C is calculated as:

\frac{C}{B} = -4

C = -4 * B

C = -4 * \frac{\pi}{6}

C = -2 * \frac{\pi}{3}

C = -\frac{2\pi}{3}

Lastly, D is calculated as:

D = Least + A

So:

D =21 + 28

D=49

So, the function is:

y = A \sin(Bx + C) + D

y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49

Plz help me I can't figure it out ​
lys-0071 [83]

Answer:

A.

\sqrt{500}

Step-by-step explanation:

when a value is outside of the root, then you can square it and put it back in. After you put it back in, you need to multiply it by the number that is remaining

In this case, you would square 10 which equals 100, and put it back into the root and multiply 100 by 5.

100x5=500

Therefore, the answer is A, root 500
