Assuming that a country's population is now 3 million and is growing exponentially with growth constant .02, what will be the average population during the next 50 years?

8074764

Step-by-step explanation:

Given that:

Using the exponential growth function :

F = a(1 + r) ^x

Where a = initial amount = 3 million ; r = rate = 0.02 ; time = x = 50 years ; F = final amount

F = 3(1 + 0.02)^50

F = 3(1.02)^50

F = 8074764.0872

Hence average population over the next 50 years will be ; 8074764

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.
