On march 31, 2009, facebook had 197 million monthly users worldwide and on march 31, 2012 had 901 million monthly users. if the relationship between the time and number of users is linear, predict the number of users on march 31, 2014.

1370.33 millions

Step-by-step explanation:

Let x be the number of years and y be the the number of users (in millions) of  after x years.

Given: On March 31, 2009,company has 197 million monthly users  . Let x=0 at year 2009.

So when x=0, y=197

On March 31, 2012 had 901 million monthly users.

So when x=3, y=901

Since, the relationship between the time and number of users is linear then the rate of change must be constant through out the years.

The rate of change=

The number of users after x years is given by :-

The number of users on March 31, 2014 (x=5) is given by

Hence, the number of users on March 31, 2014 = 1370.33 millions.

hope i'm right lol

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
