Source region(s) for air masses are where winds are and the surface is
middle latitudes, strong, rough terrain subarctic and subtropical, light, flat

middle latitudes, light, surface is flat

Explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

According to Geographical studies , source region(s) for air masses are middle latitudes where winds are light and the surface is flat. They then move and collide with winds from other areas and create interesting weather effects.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
