Feel free to answer any of the following questions! 1) The recursive formula for a sequence is f(n) = f(n – 1) + 12, where f(n) is the nth term of the sequence and f(1) = 19. Write an explicit formula that can be used to determine the nth term of the sequence
2) The recursive formula to describe a sequence is a^1=3 and a^n=1+2a^n-1. State the first four terms of this sequence.
3) Can the sequence a^1=3 and a^n=1+2a^n-1 be represented using an explicit geometric formula? Justify your answer.
4) Consider the series described as: -10 + -6 + -2 + … + 78 + 82 Is this series arithmetic or geometric? Justify your answer.
5) Consider the series described as: -10 + -6 + -2 + … + 78 + 82 Find the sum of the twenty-four terms in the series.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

step-by-step explanation: w

explanation:

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
