Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping 
So, if you have a x/y values table, you simply have to change sign to all the values in the y column.
Answer:
She used the simple random sampling technique because there was no condition attached to the samples she took.
Step-by-step explanation:
we have basically four types of sampling
1.Simple random sampling.
2.Systematic sampling.
3.Stratified sampling.
4.Cluster sampling.
simple Random sampling: is a sampling technique where every item in the population has an even chance and likelihood of being selected in the sample.
Formula for area of a circle: Pi * R^2.
Radius = diameter/2
Radius = 16m/2
Radius = 8m
Formula and equation:
Pi * (8)^2
= Pi * 64m2
= 201.0 m2.
So, in conclusion, the answer to this question is C)64 * Pi * m^2.

-------
a) 12
b) -2
Step-by-step explanation:
The initial value of the line is always the constant at the end of the equation.
The rate of change is always the coefficient of x.
