19. Deanna received an e-mail asking her to forward it to 1.0 other people. Assume that no one
breaks the chain and that there are no duplicate recipients. How many e-mails will have been sent
after 8 generations, including Deanna's.

Respuesta :

Answer:

111 111 110 .

Step-by-step explanation:

Deanna's generation is  10^1    ( hers and 9 others that received it)

                      then each of those 10... send out 10

                                       =     10 *10  = 10^2     this is generation 2

                                                 then   generation 8 will be 10^8

Now you have to add them all together

10^1 + 10^2 + 10^3 ......+ 10^8

= 111 111 110 e-mails
