Um carro percorre um trecho de uma estrada com velocidade escalar média de 90Km/h. Calcule a distância percorrida pelo carro após 4h15min de viagem

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
