Heya! I would greatly appreciate if anyone could help me with these two questions. I don't exactly understand them that well. Thank you! 1. "Tony Schumacher is a NHRA Top Fuel drag racer. He holds the world record for the fastest quarter mile pass where he reached a speed of 150.2 m/s is 3.667 seconds. What was his acceleration?"
2. "An F16 fighter jet at a high altitude is flying at 472 m/s and acceleration to 611 m/s in 7.2 seconds. What is the acceleration of the fighter jet?"

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.
