Is the change constant or not constant?
If so how can you tell?

Yes, because the distance increases by 50 each hour.

Step-by-step explanation:

If you look at the right side of the graph, it increases by 50 each hour.

Just calculate! :)

Hope this helps! :)

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

answer: what are the following choices
