Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
So first you need to do the discount
(95)(0.9) = 85.5
then add the 4.5% sales tax:
(85.5)(1.045) = $89.35
