)given that 1 inch = 0.0254 m, 1 mile = 1760 yards and 1 yard = 36 inches. convert 5
miles into kilometres.

8.04672 KM

Explanation:

5 miles = 5×1760 yards = 8800 yards

8800 yards = 8800×36 inches = 316800 inches

316800 inches = 316800 x 0.0254 m = 8046.72 m

8046.72 m = 8.04672 kilometers

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.

dang that balls went far
