It is estimated that 26 large pizzas are about right to serve 66 students of a physics club meeting. how many pizzas would be required if the group, because of a conflicting math club meeting, was only going to have 38 students in attendance?

The answer to your question is: 15 pizzas

Explanation:

data

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.
