Answer:

discriminant=D=0

Step-by-step explanation:

given, 9x^2-18x+9=0...............(1)

equ (1) divided by 9

x^2-2x+1=0

discriminant=D=b^2-4ac

where, b=-2, a=1, c=1

D=(-2)^2- $4\times 1\times 1$

D=4-4=0

D=0

hence discriminant=D=0 answer

$\text{Hello there!}\\\\\text{We're trying to find the rate of change of the population}\\\\\text{We see that the population increased over time, meaning that our rate of}\\\text{change would be positive}\\\text{We know that:}\\\\\text{In 2007 = 215,000 people}\\\\\text{In 1990 = 123,000 people}\\\\\text{Subtract 215,000 by 123,000}\\\\215000-123000= 92,000\,\text{increase in the population}\\\\2007-1990 = 17\,\text{years}\\\\\text{Divide 92,000 by 17}\\\\92000\div17=5,411.76\\$
