Why would you get a more accurate measure of the volume of an irregular solid by using displacement instead of measuring with a ruler?

Displacement method

Explanation:Placing irregular object in a Tube and then measuring the amount of water that either gets displaced from the container or goes up with the creatube and then measuring the amount of water that either gets displaced from the container or goes showing how much volume irregular object is.

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.
