Two points are defined as (x1, y1) and (x2, y2) when plotted on a rectangular coordinate grid. find the distance, d, between the two points ( -3, 1) and (6, -9)

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

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
