Which pair of points tells you the relation is NOT a function? {(1, 4), (8, 4), (3, 1), (1, 0), (6, 3)}
answers:
(1, 4) and (1, 0)

(1, 4) and (6, 3)

(1, 4) and (8, 4)

(1, 4) and (3, 1)

(1, 4) and (1, 0)

Step-by-step explanation:

for a function each input has one output we cant have a function if there are two of the same inputs 1 and 1 or 2 and 2 that have two different outputs

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

you have to put the graph on here with the question
