Answer:

Step-by-step explanation:
Given

How far did they row together
To do this, we simply add the distance they both covered.

This gives;

Take LCM


Simplify

<em>Hence, they both rowed 1/2 mile</em>
 
        
             
        
        
        
So 20=2 itmes m2 times 5
5m=5 times m
so
5m=20
5 times m=2 times 2 times 5
divid eboth sides y 5
m=2 times 2
m=4
        
             
        
        
        
Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 =   5 e^r * t  is the equation being used where  t = 15
7/5 = e^r * t 
ln 7/5 = r * t     taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t)    is then our equation
Check  - suppose you want y at 2020
y = 5 e^(.0224 * 20)    would be the equation
y = 5 e^.449 = 7.83  billion - seems to be a reasonable answer
