Answer: Approximately 25187 animals of this species will be left in 2025
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
y = b(1 - r)^x
Where
y represents the population of animals after x years.
x represents the number of years.
b represents the initial population of animals.
r represents rate of decay.
From the information given,
b = 200000
r = 4.5% = 4.5/100 = 0.045
x = 2025 - 1980 = 45 years
Therefore,
y = 200000(1 - 0.045)^45
y = 200000(0.955)^45
y = 25187

Answer:
Slope is -93/97
Step-by-step explanation:
To find slope subtract the y's and put that answer in top of a fraction. Then subtract the x's and put that on the bottom of the fraction. If its a smaller number on top and bigger number on the bottom, that is a proper fraction. If the bigger number is on top then it is an improper fraction. If it divides evenly, then the answer will just be a whole number (what the questions calls an integer) All these answers can be positive or negative.
***BUT, you have to start the subtractions with the same point!!!
Let's start with (-2, 95) in front, for both subtractions. (But it could be either point, the answer comes out the same)
Subtract y's: 95-2 is 93.
Subtract x's: -2 - 95 is -97
The slope is 93/-97 it is a proper fraction.
We can put the negative sign in front instead of at the bottom, it looks better.(and is the same)
Slope is -93/97
