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

How many 9 digit palindromes are there with all the digits being even and each digit appearing no more than once
likoan [24]

Answer:

96

Step-by-step explanation:

We have to find number of 9 digit palindromes  when all digits are even and each digit appearing not more than twice.

Digits used here

0,1,2,3,4,5,6,7,8,9

Total number of even digits=0,2,4,6,8=5

Now,

0 cannot be used for first place if number is 9-digit number.

Firs place can be filled by number of ways=4

Second place can be filled by number of ways=4

Third place can be filled by number of ways=3

Fourth place can be filled by number of ways=2

Fifth place can be filled by number of ways=1

Total number of ways=4\times 4\times 3\times 2\times 1

Total number of ways=96

Hence, total number of 9-digits palindromes  when all digits are even and appearing not more than twice=96
