<h3>
Answer: Yes, it is a function</h3>
This is a function because there are no x values that repeat.
If we had repeated x values, then this would mean a certain input x leads to multiple outputs y, and that would not make it a function.
For instance, if we had (2,1) and (2,2) at the same time, then the input x = 2 leads to multiple outputs y = 1 and y = 2 at the same time. A function would not be possible in this example.
A function is only possible if any input x leads to exactly one output y. It is possible for y to repeat itself and still have a function.
Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.

The two points are C(2,-1) and D(5,3). Using the distance formula, we get



On further simplification, we get



The distance from point C to D is 5 units. Therefore, the correct option is A.
0.25=25/100=1/4. 1/4×84=84/4=21. The answer is 21
Answer:
The numbers are codes that Russians used to communicate with their spies. Historically they really did have "number stations" where they broadcast series of numbers in radio. ... Hudson repeats the numbers to Mason over and over throughout the interrogation, hoping he can translate it.
