club charges a yearly fee of $450 plus $10 for each session with a personal trainer. for what number on
sessions will the costs be the same? show all work

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

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
