Evaluate the geometric series. Round to the nearest hundredth. Help me please!!

7.50

Step-by-step explanation:

The n th term of a geometric series is

= a

where a is the first term and r the common ratio

5 is the n th term of a geometric series

with a = 5 and r =

The sum to n terms of a geometric series is

= , thus

=

     =

     =

     = × 0.9999..

     = 7.5 × 0.9999...

      ≈ 7.50 ( to the nearest hundredth )

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 : )
