Which of the following accurately describes cot(336°)
Options are
cot(-336°)
cot(24°)
cot(-24°)
-cot(-24°)
Answer : cot(-24°)
In a circle the total angle is 360 degrees. 336 degree lies in fourth quadrant.
360 degree - 336 degree = 24 degree
+24° lies on first quadrant and -24° lies on fourth quadrant.
So cot(336) is same as cot(-24)

Answer:
8 hours
Step-by-step explanation:
The equation is 2.25X + 3.50 = 21.50
X represents the unknown amount of hours she worked. 2.25 is the cost per hour. 3.50 is the fee she charges for every gig. That fee only happens once a gig so naturally it wasn't the number x was placed with.
2.25X + 3.50 = 21.50
2.25X + 3.50 - 3.50 = 21.50 - 3.50
2.25X = 18
<u>2.25X</u> = <u>1</u><u>8</u>
2.25 2.25
X = 8
