The one with domain {8, 3, 1} and range {6, 2, 7, 9}(top-left) is not a function because 3 is being mapped to two different values, 2 and 7.
Hope this helps bye bye thanks
Answer:
21, 34, and 55 because it's like that one ratio, I forgot the name tho
The standard conversion toolbox:
x=rcos(θ)
y=rsin(θ)
Here r=7csc(θ)
so
x=7csc(θ)*cos(θ)=7cos(θ)/sin(θ)=7cot(<span>θ)
y=7csc(</span>θ)*sin(θ)=7sin(θ)/sin(<span>θ) = 7
therefore the rectangular coordinates are (7cot(</span><span>θ), 7)</span>
(11/2) x ((3/7) / (3/10)
(11/2) x (3/7) x (10/3)
330/42
7 6/7 or 7.857142857 ( or 7.86 rounded to nearest hundredth)
