Xelga [282]

Answer:

Step-by-step explanation:

9x+\frac{1}{3}=x-13

9x*3+1/3=x-13

27x+1=3x-39

27x-3x=-39-1

24x=-40

x=-5/3

x=-5/3

In the year 2005, a total of 750 fish were introduced into a manmade lake. The fish population was expected to grow at a rate of
rewona [7]
Exponential change can be modeled by:
N = N(0) x λⁿ; where λ is the rate of change. It is greater than 1 when there is growth and less than 1 when there is decay. n is the number of time periods passed.
λ is 1 + 0.083 = 1.083
N(0) is the initial value of 750
n is 2050 - 2005 = 45 years
N = 750 x (1.083)⁴⁵
= 27,000 fish
