Which represents a function?

  the table

Step-by-step explanation:

Any mapping (graph, table, diagram, or ordered pairs) in which the same x-value gives two or more y-values (range values) is NOT a function.

In the diagram, -2 gives two outputs; in the ordered pairs, 6 gives two outputs. Neither the diagram nor the set of ordered pairs represents a function.

The table has unique values in the x-column, so it is a function.

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50

step-by-step explanation:

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
