A baseball is thrown with a speed of 36 meters per second (m/s). What is the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand
and cross the plate?
72 meters
41 meters
31 meters
18 meters

18 meters

36m/s ÷ 2 = 18 m/s

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.
