Answer:
a)264 feet/ second
b)5280 feet during 20 seconds
Step-by-step explanation:
A parachutist's rate during a free fall reaches 80 meters per second.
Convert the rate in feet per second
We are given that meter is equal to 3.3 feet
So, So, rate in feet per second =
So, parachutist fall in 1 second = 264 feet
Parachutist fall in 20 second =
Hence the parachutist will fall 5280 feet during 20 seconds of free fall

Answer:
A) 63.36 years.
B) 100.42 years.
Step-by-step explanation:
We have been given that the population of the world was 7.1 billion in 2013, and the observed relative growth rate was 1.1% per year.
A) Since we know that population increases exponentially, therefore we will use our given information to form an exponential model for population increase and then we will solve for the time by which our population will be double.
Now let us solve for t using logarithm.
Therefore, it will take 63.36 years the population to be double.
B) Now we will find the number of years it will take the population to be triple of its size.
Now let us solve for t using logarithm.
Therefore, it will take 100.42 years the population to triple of its size.
Hope that helps you, Good luck!
