Answer: In 2008 the population was 21,525,144
Step-by-step explanation:
 You need to use the following formula for Exponential decay:
 
 Where  is the initial population in the year 0,
 is the initial population in the year 0,  is the rate of decay and
 is the rate of decay and  is the time.
 is the time.
 In this case, you can identify that:
 
 Therefore, substituting these values into the formula for Exponential decay, you get:
 
 Then, in 2008 the population was 21,525,144
 
        
             
        
        
        
Step-by-step explanation:
take the right triangle
15^2 = 9^2 + x^2
225 = 81 + x^2
x = 12
area of square b = 144

Answer:
F=73.74 degrees
Step-by-step explanation:
sin=opposite/hypotenuse
opp=24 hyp=25
sin(F)=24/25 (to find angle have to use inverse sin)
sin-1(24/25)=73.74
