3. A rumour is being spread in a community that the president is going to retire before the next election 2015. Initially 2 people were told the rumour and each of these people told 2 others the following day. Each of the 2 people told by the initial people told 2 others the day after they were told. If this process keeps up, how many people will be told the rumour on the fifth day?

I'm not sure if that's what is meant cuz the text is a little ambiguous

Nevertheless, 62 people

Step-by-step explanation:

Amount = 2 + 4 + 8 + 16 + 32 =62 people

"Exponential Growth"

62

Step-by-step explanation:

You start with 2 people on day 1. On day 2 each one of them tells 2 other people, which means 4 new people are told the rumor. We can use the formula p(d)= n + n^n + n^(n+1) + n^(n+2) d times, where p(d) is the number of people told the rumor on the day d, n being the Number of people told by each person every day, as well as the initial people. So the formula is

p(5)= 2 + 2^2 + 2^3 + 2^4 + 2^5 = 2+4+8+16+32 = 62

62 people are told the rumor on the fifth day.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10
