Answer:
this isnt the answer but it helps solve the equation so here is a little explanation
Step-by-step explanation:
Cost Equation
-Is a mathematical equation for a straight line, to predict total cost.
-Total cost = total variable cost + total fixed cost or Y = vx + f
-Y = total mixed cost
v = variable cost per unit of activity
x = volume of activity
f = fixed cost over a given period of time
Answer:
sin(x - y) = 0.21
Step-by-step explanation:
we have the sin values which we need to get cos values
sin (A-B) = sin A cos B - sin B cos A
sin² A + cos² A = 1
sin x = 4/9
cos² x = 1 - sin² x = 1 - 16/81 = 65/81
cos² x = 65/81
cos x = √65/9
sin y = 1/4
cos² y = 1 - sin² y = 1 - 1/16 = 15/16
cos² y = 15/16
cos y = √15/4
sin(x − y) = sin x cos y - sin y cos x
sin(x - y) = 4/9 √15/4 - 1/4 √65/9
sin(x - y) = (4√15-√65)/36
sin(x - y) = 0.21
