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

Answer:

D. 32 times; 5/4*40 = 32

Step-by-step explanation:

It is expected the spinner to land on Red 1/5 times.

If the spinner is spun 40 times, then it should land on Red:

1/5*40 = 8 times

And it should not land on red:

(1 - 1/5)*40 = 4/5*40 = 32 times

Correct choice is D
