The speed of a note created by a flute will increase as the speed of sound increases. when a marching band goes outside on a cold day, what would you predict would happen to the note played on a flute?
a) it would decrease because the speed of sound and temperature are proportional.
b) it would increase because the speed of sound and temperature are proportional.
c) it would decrease because the speed of sound and temperature are inversely proportional.
d) it would increase because the speed of sound and temperature are inversely proportional.

a

Explanation:

It would decrease because the speed of sound and temperature are proportional. Sound will travel faster when the temperature increases.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

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.
