Use the graph below to fill in the blank with the correct number:

f(0) =

1

Step-by-step explanation:

We are given a graph, in which x is independent value and y is dependent on the value of x.

f(0) means that x = 0.

so,

we will see in the graph where the x = 0

Obviously it can be anywhere either on origin or on y-axis. The point mark on y-axis is when y = 1

the y will be in still but your answer will be y x 3

step-by-step explanation:

jk: )

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
