A rocket travels 200,000 meters in a time of 4.40 seconds . what of the speed of the rocket ?

the speed of the rocket is 45454.5455

Explanation: Because the speed formula is basically just distance/ divided by time all you need to do is divide 200,000 meters by 4.40 seconds. And then thus you will get the speed.

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.

inverse v=i*r
