HELP PLZ i just want to know to steps of solving this A car (2000kg) travels down a circular hill of radius 30m. The car’s tires can only withstand a maximum normal force of 50,000N without blowing out. What is the maximum speed the car can travel without blowing out the tires (getting a flat!)

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.
