O
A. Endothermic, because energy is absorbed from the surroundings
O
B. Exothermic, because energy is absorbed from the surroundings
O
C. Exothermic, because energy is released to the surroundings
D. Endothermic, because energy is released to the surroundings

The correct option is A. Endothermic, because energy is absorbed from the surroundings

Explanation:

A decomposition reaction can be described as a type of reaction in which a product breaks down into the reactants.

As energy is required for the product to break down, we can infer that the reaction is endothermic. This is because in an endothermic reaction, energy is taken from the environment to break down a compound or product.

show the diagram then i will answer

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.
