Answer: 137,375,958
Step-by-step explanation:
Exponential growth equation:
, where A = initial population , x= time , r =rate of growth.
As per given: r = 1.7% = 0.017
Population of Mexico in 2003 : A= 104900000
In 2019 , x = 2019-2003 = 16
Population in Mexico :
Population of Mexico in 2019 = 137,375,958
<h2>Answer:</h2>
The equation that will be used to find t is:
Total distance that is traveled by Amir is: 5 miles.
and the total time taken by him is: 2 hours.
On the first part of the hike, Amir averaged 3 miles per hour.
Let t denote the time he spent hiking during the second i.e. difficult part of the hike.
- Hence, the time he spent in first part of hike is: 2-t
( Since, the total time was 2 hours)
Also, we know that:
Hence, distance traveled in first part of hike is:
- Now, the distance he will travel in second part of hike will be: 5-3(2-t)
Since the total distance traveled by him is 5 miles.
It is given that his speed decreased to 1.5 miles per hour.
Now, we know that:
Hence, time spent by him in second part of hike is:
