34. To cover their tracks, some criminals decide to roll their getaway car down a hill and off a cliff, where it crashes into a river 40.5 m below. The car is moving horizontally as it leaves
the cliff and the bad guys hear the sound of its splash 3.008 s after the car becomes airborne.
Assuming the speed of sound in air is 342 m/s, determine the speed of the car as it leaves
the cliff.

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.
