Aplane is flying east when it drops some supplies to a designated target below. the supplies land after falling for 10 seconds. how high above the ground was the airplane when the supplies were dropped? 120 meters490 meters980 meters49 metersas the supplies fell, they traveled 650 meters horizontally. how fast were the supplies and the airplane moving forward? remember that it took 10 seconds for them to reach the ground.65 m/s6500 m/s0.154 m/s660 m/s

Part 1)

here we know that supply took 10 s to reach the ground

so here we will have

Part 2)

Here all the supply covered horizontal distance of 650 m in 10 s interval of time

so here we can say

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.
