The total cost to rent a rowboat is $18 times the number of hours the boat is used. write an equation to model this situation if c equals total cost and h equals number of hours? answer choices - c-18=h h=18c c=h/18 c=18h

Step-by-step explanation:

Let

C------> represent the total cost

h-----> represent the number of hours

we know that

-----> linear direct variation that represent the situation

In this problem the constant of proportionality k is equal to the slope m of the line

so

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
