Answer:
S={( 1 )}
Step-by-step explanation:
-3x²+6x+1=4
-3x²+6x+1-4=0
-3x²+6x-3=0
∆=b²-4.a.c
∆=(6)²-4.(-3).(-3)
∆=36-36
∆=0
x'=x"=-b/2a=-(+6)/2.(-3)=-6/-6=1
Answer:
5/16
Step-by-step explanation:
As you can see in the 16 given possible outcomes, in 5 of them at least 3 coins land facing up. Since there are 16 outcomes in total, the probability that at least three coins land facing up is 5/16. Hope this helps!
Answer:
11 ft
Step-by-step explanation:
The equation for the volume of a cone is:
V = 1/3(3.14)r^2h
V = 414.48
r = 6
Plug in those values and solve for h:
414.48 = 1/3(3.14)(6)^2h
414.48 = 37.68h ; divide both sides by 37.68
11 = h
The missing height is 11ft.
Answer:
(0, - 6)
Step-by-step explanation:
Since this is a vertical line then the midpoint of the y- coordinates is
(0 - 12) = - 6
⇒ midpoint = (0, - 6 )
The expression that lists all numbers in prime numbers would be A. All numbers here are prime numbers, and is in the simplified form, the remaining choices are not in their simplified forms and can be broken down into smaller numbers that multiply to give their value.
