Answer:
Pop in 1990 = 81 million rats
Pop in 2005 = 127 million rats
Step-by-step explanation:
Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.
The rat population in 2005 is given by the formula when t = 15
This is: approximately 127 million rats.
Use the quadratic formula:-
x = [-(-8) +/- sqrt((-8)^2 -4*41)] / 2
x = ( 8 + sqrt (-100) / 2 and (8 - sqrt(-100) / 2
= 4 + 5i , 4 - 5i Answer
