Answer:
Total cost= $39
Step-by-step explanation:
Giving the following information:
At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75.
<u>First, we will establish the total cost formula:</u>
Total cost= 5.5p + 3.75d
p= number of bags of popcorn
d= number of drinks
<u>Now, for 3 bags and 6 drinks:</u>
Total cost= 5.5*3 + 3.75*6
Total cost= $39
A quadrant is the area that is divided into the x and y axes
The quadrants in which tan
and cot
are positive are I and III
<h3>How to determine the quadrants</h3>
The tangent of an angle is calculated as:
![\tan(\theta) = \frac{sin(\theta)}{\cos(\theta)}](https://tex.z-dn.net/?f=%5Ctan%28%5Ctheta%29%20%3D%20%5Cfrac%7Bsin%28%5Ctheta%29%7D%7B%5Ccos%28%5Ctheta%29%7D)
While the cotangent of the angle is calculated as:
![\cot(\theta) = \frac{cos(\theta)}{\sin(\theta)}](https://tex.z-dn.net/?f=%5Ccot%28%5Ctheta%29%20%3D%20%5Cfrac%7Bcos%28%5Ctheta%29%7D%7B%5Csin%28%5Ctheta%29%7D)
The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
- In the first quadrant, the sine and the cosine angles are positive.
- In the third quadrant, the sine and the cosine angles are negative.
Hence, the quadrants in which tan
and cot
are positive are I and III
