What can we say about the velocity of a car which has negative acceleration in the x-direction? multiplechoice : 1) the x-component of it's velocity is decreasing. 2) the x-component of its velocity is positive. 3) it is slowing down. 4) the x-component of its velocity is negative. 5) it is speeding up. 6) the x-component of it's velocity is increasing.

answer; i believe that the correct answer is (d) a very small amount of mass

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.
