Dexter needs to monitor the movement of a rover vehicle on mars for one year. which technologies should dexter use for tracking purposes? check all that apply. telescopes that show where the rover vehicle is located satellites that collect information about rover vehicle distance space stations that store real-time data about rover vehicle speed computer simulations that model how long it takes the rover to get to mars doppler radar that records information about weather the rover is exposed to

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.

total distance/total time

(85 + 82)/(5+3)

167/8

20 just over
