The population of a certain community is increasing at a rate directly proportional to the population at any time t. in the last 7 years, the population has doubled. how long will it take for the population to triple?

11.08 years

Step-by-step explanation:

Given that the  population of a certain community is increasing at a rate directly proportional to the population at any time t.

i.e.

Separate the variable and integrate to get

ln P = k t +C

When t=0 initial population =A

When t=7, P has become 2A

Hence equation is

When tripled we get

14

step-by-step explanation:

14 x 3 = 42

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
