Answer:
Step-by-step explanation:
Regular coordinates (x, y)
Polar coordinates (r, φ)
We have the point
Substitute:
LCD is 20
3/5 -> 12/20
1/20 -> 1/20
Answer:
The table represents a function because each input corresponds to exactly one output.
Step-by-step explanation:
A table can be regarded as representing a function if and only if every input can only be mapped to exactly one output. In other words, it means, only 1 exact output can be assigned to an input. In a table of function, an input cannot have two different outputs. Although, two different inputs can be assigned to the same output.
From the table given, we see that every input has exactly one output. Although, we have different inputs that gives the same output.
Therefore, we can conclude that the table represents a function because each input corresponds to exactly one output.
