Answer:
Therefore the initial amount of animal was 89.
Step-by-step explanation:
Given that,at rate of 3.5% per year, the population of a certain animal species decreases.
The population growth formula:
A= number of population after n year.
P= initial population.
n= time in year
r= rate of growth per annum.
Here A=80, P=?, n= 3 years, r= -3.5% = -0.035[ since the rate of growth decrease]
Putting the all values,
≈89.
Therefore the amount of animal at its initial stage was 89.
The rate of change is the slope, the coefficient of the independent variable divided by the coefficient of the dependent variable. When the coefficient of the dependent variable (usually represented by y) is 1, the slope is just the coefficient of the independent variable (usually represented by x).

Answer:-16
Step-by-step I looked it up
I believe the answer is B. The square root of 25 is 5. You cannot find the square root of a. b^6 would become b^3 because of the laws of exponents.
