Answer:
asymptotes: x = ±6
zero: x = 0
Step-by-step explanation:
The vertical asymptotes of the function will be at the values of x where the denominator is zero. The denominator is x^2 -36, so has zeros for values of x that satisfy ...
x^2 -36 = 0
x^2 = 36
x = ±√36 = ±6
The vertical asymptotes of the function are x = -6 and x = +6.
The zero of the function is at the value of x that makes the numerator zero. This will be the value of x that satisfies ...
6x = 0
x = 0 . . . . . divide by 6
The zero of the function is x=0.
__As a check on this work, we have had a graphing calculator graph the function and identify the zero.

Answer:
So, the sample mean is 31.3.
So, the sample standard deviation is 6.98.
Step-by-step explanation:
We have a list of data for the speeds (in miles per hour) of the 20 vehicles. So, N=20.
We calculate the sample mean :
So, the sample mean is 31.3.
We use the formula for a sample standard deviation:
Now, we calculate the sum
Therefore, we get
So, the sample standard deviation is 6.98.
