1. Mrs. Smith paid $9.45 for 3 pounds of ground beef. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of ground beef, x? O Not here 3.15 O 3 9.45 CLEAR ALL

ok bro so its gotta be 3.15

Step-by-step explanation:

9.45/3= 3.15 so yea

77

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
