Answer:
Part 1) Australia 
Part 2) China 
Part 3) Mexico 
Part 4) Zaire 
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
P(t) is the population
t is the number of years since year 2000
a is he initial value
r is the rate of change
Part 1) Australia
we have

substitute


Find the  expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Part 2) China
we have

substitute


Find the  expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Part 3) Mexico
we have

substitute


Find the  expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Part 4) Zaire
we have

substitute


Find the  expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Answer:
0=-31
Step-by-step explanation:
 
        
             
        
        
        
First you put the equation in point slope form- Y-0= 5x - 4
Then add the zero to the 4.
Final answer: y= 5x -4
        
             
        
        
        
So square feet is area which is legnth times width or area=lw or a=lw
width=w=2 2/4
2/4=1/2
w=2 1/2=5/2
a=lw
11 11/16=187/16
187/16=l(5/2)
multiply both sides by 2/5 to clear the fraction (1/2 times 2/1=2/2=1)
374/80=legnth
simplify
374/80=187/40=4 27/40=legnth
legnh must be less than 5 and 4 and 27/40 is less than 5 so it will fit
