Answer:
6045000000000000000000000 kg.
Step-by-step explanation:
We have been given that the mass of Earth is kg. The mass of the Moon is
kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.
Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.
As we already have the model that describes the change of the population in Italy in terms of the years that have elapsed, we only have to replace the conditions that are requested in that equation.
Therefore to find the population of Italy in the year 2000 (t = 10 years) substitute t = 10 in the equation and have:
million people
To find the population of Italy in 2008 (t = 18 years)
substitute t = 18 in the equation and have:
million people
To predict the population in Italy for 2015 and 2020 with this model, we substitute in the equation t = 25 and t = 30
t = 25
million people
t = 30
million people
