Answer:
A = 236,000 (1+ 0.04)^9
335,902 people in 2009
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population (in 2000)
r = growing rate (decimal form) = 4/100 = 0.04
t= years
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04) ^t
To find the population in 2009:
We have to calculate the number of years passed since 2000: (2009-2000 = 9 years =t)
Substituting t=9 in the function:
A = 236,000 (1+ 0.04)^9
A =335,902 people

Answer:
2x/(x+3) +3/(x-3) = 8/(x^2
[2x(x-3) +3(x+3)]\( x^2 - 9) =8/(x^2 -9)
2x^2 -6x +3x +9=8 (x^2 -9) /(x^2 -9)
2 x^2 -3x +9 -8=0
2 x^2 -3x +1 =0
2x^2 -2x -1x +1 =0
2x(x-1) -1(x-1)=0
(x-1)(2x-1)=0
either, or, 2x-1=0
x-1 =0 2x =1
x =1 x= 1/2
hence, x= 1, 1/2
Step-by-step explanation:
The digital root of a number is the single digit that you get by adding all of the digits of the original number together. If the result of that is multiple digits, you add those digits together, repeating the process until you get a single digit. That digit is the digital root of the original number.
