Ageologist finds an area of undisturbed sedimentary rock the lowest layer is most likely the question 3 options: newest oldest radioactive superposition

The undistributed sedimentary rock which has been found by the geologist has the oldest layer at the lowest layer or the bottom of the rock.

Option B

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.
