a successful music app tracked the number of downloads each day for 4 artists, represented by lines l, j, m and d over the course of a month. which lines represent an artist whose download remained consistent

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

i think asking google will you get the answer to that question

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
