Answer:
a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal figure.
Step-by-step explanation:
Answer:
The feature that makes the sample representative of the population is the choice of the contact mode (telephone landline or cellular phone line) with proportions representative of the ages of the subjects to be represented.
Step-by-step explanation:
The feature that makes the sample representative of the population is the choice of the contact mode (telephone landline or cellular phone line) with proportions representative of the ages of the subjects to be represented.
Older people tend to manage with landline phones, while younger people tend to have no landline phones but cell phone. Both groups must be proportionally represented to be representative of an adult population (18 years or older).
Therefore the graph represents a non linear function.
Example of a linear function
ax+by=c
Example of non linear function
y²= 4ax
Step-by-step explanation:
The equation of line which passes through the line (0,4)and(1,8) is
[ here 
and 
]
If a line passes through the points(0,4) ,(1,8) and (2,10) .Then (2,10) will satisfies the equation of line.
L.H.S = 10 -4(2) -4
=10-8-4
=-2 ≠ R.H.S
Therefore the graph represents a non linear function.

ax+by=c
Example of non linear function
