Answer:
√3/11, π/24, 3/25, 9/100
Step-by-step explanation:
The 2-decimal value of each of the numbers is ...
9/100 = 0.09
π/24 = 0.13
3/25 = 0.12
√3/11 = 0.16
Then the order from greatest to least is 0.16, 0.13, 0.12, 0.09. In the original form, that is ...
√3/11, π/24, 3/25, 9/100 . . . . . matches choice B
Try this explanation:
1. if to simplify the equation into the form ax²+bx+c=0 then to calculate 'D' ⇒ x²-8x-20=0; D=16+20=36. The value of D is greater 0, it means the given equation has two solutions.
2. Wrong step and correct way are shown in the picture in the attachment.
3. Description of the solution: the points with x=1;3 are the intersection points of the function y=x²-4x+3 and Ox-axis.
PS. all the details are in the attachment.
