A communications satellite is in a synchronous orbit that is 3.6 x 107 m directly above the equator. The satellite is located between two cities almost on the equator that are separated by a distance of 2.9 x 106 m. Find the time it takes for a telephone call to go by way of satellite between these cities. Ignore the curvature of the earth.

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.
