What is the sum of the first 30 terms of this arithmetic sequence?

6, 13, 20, 27, 34, …

3225

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

= [ 2a + (n - 1)d ]

where a is the first term and d the common difference

here a = 6 and

d = 13 - 6 = 20 - 13 = 7, hence

= [ (2 × 6) + (29 × 7) ]

                          = 15(12 + 203) = 15 × 215 = 3225

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
