Answer: 
Option D(No because the wrist circumference of 16 cm is paired with two heights.
Step-by-step explanation:
In the given graph we have  set of points representing the wrist circumferences and heights of six students in Alyssa’s classroom. 
x axis  represents the wrist circumference while  y axis represent the height.
Any relation is called a function if for one value of x we have only one value of y. If the graph passes the vertical line test that is if a vertical line drawn touches the graph at only one point then the graph is called a function.In the given graph for x value x=16 there are two y values 162 and 165.So the graph is not a function.
Among all the options Option D(No because the wrist circumference of 16 cm is paired with two heights.) is the right answer.
 
        
                    
             
        
        
        
Answer:
m = 44
Step-by-step explanation:
USe the pythagoream thyroem a^2 + b^2 = m^2. so 10^2 + m = 12^2
or 100 + m = 144. subtract 100 from both sides, you get m = 44

Answer:
11
Step-by-step explanation:
The third term is when n = 3, so simply plug 3 into the equation:
f(3) = 3 * 3 + 2 = 9 + 2 = 11
Thus, the answer is 11.
