Answer:
cosФ =
, sinФ =
, tanФ = -8, secФ =
, cscФ =
, cotФ = 
Step-by-step explanation:
If a point (x, y) lies on the terminal side of angle Ф in standard position, then the six trigonometry functions are:
- cosФ =

- sinФ =

- tanФ =

- secФ =

- cscФ =

- cotФ =

- Where r =
(the length of the terminal side from the origin to point (x, y)
- You should find the quadrant of (x, y) to adjust the sign of each function
∵ Point (1, -8) lies on the terminal side of angle Ф in standard position
∵ x is positive and y is negative
→ That means the point lies on the 4th quadrant
∴ Angle Ф is on the 4th quadrant
∵ In the 4th quadrant cosФ and secФ only have positive values
∴ sinФ, secФ, tanФ, and cotФ have negative values
→ let us find r
∵ r = 
∵ x = 1 and y = -8
∴ r = 
→ Use the rules above to find the six trigonometric functions of Ф
∵ cosФ = 
∴ cosФ =
∵ sinФ = 
∴ sinФ = 
∵ tanФ = 
∴ tanФ =
= -8
∵ secФ = 
∴ secФ =
= 
∵ cscФ = 
∴ cscФ = 
∵ cotФ = 
∴ cotФ =
Answer:
78 customers
Step-by-step explanation:
The only customers who didn't have pepperoni or sausage was the 20 who ordered with only onions and if you remove those 20 from the 98 total orders you are left with 78 customers who order their pizza with pepperoni or sausage (or both)?
Answer:
7.125
Step-by-step explanation:
Convert each fraction to a decimal
1/4=.25 = 8.250
1/2=.5 = 6.500
5/8=.625 = 6.625
Then, add all of them together
8.250+6.500+6.625=21.375
Lastly, divide by 3 because that's how many values you have
21.375/3=7.125
Do you have a picture of the question? From what I can tell if both question marks represent the same number, the answer is -3.125 but I’d hate be be overthinking a more simple question. Here’s my work but if I looks too confusing it probably is and I read the question wrong
