What is the common ratio, r, for the geometric sequence below? 24 = -1, and an = fan-1 for n= 2, 3, 4, ...

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

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

the 3rd on is correct
