Question 3 4 pts
If you rewrite y = 2x2 - 20x + 3 into the form Y = alx - h)2 + k which of the following is
equivalent?
O y = 2(x + 5)2-47
O Y = 2(x + 5)2 + 153
O y = 2(x - 5)2 + 153
O y = 2(x - 5)2 - 47

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
