Answer:
Option B: |x - 27.6| = 5.3
Step-by-step explanation:
We are told that the average time for athletes on the Central High School track team to run 200 meters is 27.6 seconds.
We are also told that the slowest and fastest recorded times varied from the average by 5.3 seconds.
This means that the slowest time varied by 5.3 seconds more than the average while the fastest time varied by 5.3 seconds less than the average.
If x is to represent the slowest or fastest time, the absolute value equation can be written as;
|x - 27.6| = 5.3
Multiple
The product of a number and any nonzero whole number
Answer:
![D.\ y = 3\sin(2(x + \frac{\pi}{4}))](https://tex.z-dn.net/?f=D.%5C%20y%20%3D%203%5Csin%282%28x%20%2B%20%5Cfrac%7B%5Cpi%7D%7B4%7D%29%29)
Step-by-step explanation:
Given
--- Amplitude
--- Right phase shift
Required
Identify the function
A sinusoidal function is defined as:
![y = A\sin(B(x + C)) + D](https://tex.z-dn.net/?f=y%20%3D%20A%5Csin%28B%28x%20%2B%20C%29%29%20%2B%20D)
Substitute values for A and C
![y = 3\sin(B(x + \frac{\pi}{4})) + D](https://tex.z-dn.net/?f=y%20%3D%203%5Csin%28B%28x%20%2B%20%5Cfrac%7B%5Cpi%7D%7B4%7D%29%29%20%2B%20D)
By comparison, only option (D) has the above format where
![y = 3\sin(2(x + \frac{\pi}{4}))](https://tex.z-dn.net/?f=y%20%3D%203%5Csin%282%28x%20%2B%20%5Cfrac%7B%5Cpi%7D%7B4%7D%29%29)
Hence (D) is correct
