A machine covers 5/8 sq ft in 1/4 of an hour, how much does it cover per hour?

20/8 or 2 1/2

Step-by-step explanation:

1/4 + 1/4 + 1/4 + 1/4 = 1

5/8 + 5/8 + 5/8 + 5/8 = 2 1/2

Hope this helps!

i think is g(1)=-1.

hope that i can

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
