Exponential equation with an k value only

The constant k is called the continuous growth (or decay) rate. In the form P(t) = P0bt, the growth rate is r = b − 1. The constant b is sometimes called the growth factor. The growth rate and growth factor are not the same.

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

a is the right answer
