A sequence is defined by f(0)=-4, f(n)=f(n-1)-2 for n>1. write a definition for the nth term.

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

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
