3 5 points
When the students arrive at the competition, it is determined that the height of the
sphere launcher can no longer be adjusted due to a mechanical malfunction.
Therefore, the spheres must be launched at a vertical position of y = 1
However, the spheres may be launched at speed voor 2V0.
In a clear, coherent paragraph-length response that may also contain diagrams
and/or equations, describe the speed at which a sphere should be launched so that
the students earn the maximum number of points in the competition.

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.

find the surface area of the sphere to the nearest square unit. use a calculator.
