There are 5 padlocks with 5 keys. Each key only opens 1 padlock. What is the least amount of trials required to guarantee that you´ll open all padlocks. Please include an explaination.

anser is a

step-by-step explanation:

negitive slope

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

a - base

b - exponent
