A snake dives toward deeper water at a rate of 10 inches per second. If the snake continues at this speed for 7 seconds, which expression represents this situation? A. 7(−10)
B. −7(−10)
C. 7÷10
D. 7÷(−10)

A

Step-by-step explanation:

The snake is diving deeper, meaning it is going below the surface which is represented by - numbers... time is never negative, therefore the answer can not be B.

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
