Answer:
C It is a linear function because there is a constant rate of change in both the input and output.
Step-by-step explanation:
With the values, you can see that the Y value is always 2.5 times the value of X. That's a constant rate of change.
Answers A and B make no sense, because the fact that the input or output values are increasing or decreasing have no impact to determine if a function is linear or not, can be linear or non-linear in all cases.
Answer D gives the definition of a linear function, but applies it to a non-linear function.
Use this formula: C=2πr. Divide 14/2 to get the radius. Substitute the radius into the formula.
The answer is 14pi units.

Answer:
2/27
Explanation:
• Number of green marbles = 2
,
• Number of blue marbles = 4
,
• Number of yellow marbles = 3
Total = 2+4+3 =9
• Probability of choosing a green marble = 2/9
,
• Probability of choosing a yellow marble = 3/9
Therefore, the possibility that the first marble is green and the second is yellow is:
<span>[-1,-1,1]
or
</span><span>[-2,-2,2]
</span>.....
Dot Product = 0
