A student studies the effect of an object's speed on its amount of kinetic energy. This graph summarizes the data from the study. Which statement best describes what the graph shows?
A. As speed increases, kinetic energy stays the same.
B. As kinetic energy increases, speed decreases exponentially.
C. As speed decreases, kinetic energy doubles each time.
D. As speed increases, kinetic energy increases exponentially.

1/0.14nm = 10^10/1.4 a lot

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.

the answer should be in the picture.
