Choose the best description of the relation shown below:
A. The relation is a function because every input has exactly one output
B. The relation is a function because every output has exactly one input
C. The relation is not a function because every input is different.
D. It is impossible to tell if the relation is a function without knowing more coordinates

There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

(2,10),(4,15),(6,20),(8,25)

This is a function because each input only has one output.

Your answer is A

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
