Answer:
5.23606798
Step-by-step explanation:
The correct option will be the last one: 
<em><u>Explanation</u></em>
The general equation for sinusoidal function is: 
, where 
Amplitude, 
frequency and 
y-intercept
Here the maximum value is 15 and the minimum value is -3. So, the distance between maximum and minimum values is 18. That means, the Amplitude, 
Frequency 
is given as 3 and y-intercept
is 6
So, the required function will be:
Answer:
y = -4.5
Step-by-step explanation:
Answer:
1.) 18 is decreasing by 83%
2.) 16 is decreasing by 12.5%
Step-by-step explanation:
Part ÷ Whole = Percent (decimal form)
1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.
2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.
