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:
The probability would be 0.9586
Step-by-step explanation:
Given,
Mean,
,
Variance, 
Standard deviation,
,
If X represents the number of items produced in a factory during a week.
Hence, the probability that this weeks production will be between 40 and 60






Using z score table
= 0.9793 - 0.0207
= 0.9586

Answer:
2 1/2 miles per hour
Step-by-step explanation:
A) Change in profit for each owner = -780/8
B) Change in profit for each owner = -$130
The total loss = $780
Number of owners = 6
The 6 owners must share the loss equally
The change in profit for each owner will be the original profit less 780/6
That is -780/6
Evaluating -780/6
Change in profit for each owner = -$130
