Correct answer only which of the following is distance divided by the change in time?

Hey again Yuii!

Distance traveled divided by the time taken to travel the distance is called speed. The formula for speed can be written as: speed = distance/time.

Hope you understand. :)

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

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.
