The six trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant. This is a first quadrant angle. sine of -17 pi over 3 is equal to square root of 3 over 2, cosine of -17 pi over 3 is equal to 1/2. tan -17 pi over 3  is equal to square root of 3. cosecant-17 pi over 3  is equal to 2/sqrt3, secant  of -17 pi over 3 is 2 while cotangent -17 pi over 3  is equal to 1/sqrt 3
        
             
        
        
        
Answer: 85
Add up all the numbers: 97+70+89+99+100+78+79+89+77+72=850
Divide 850 by the amount of numbers:
850/10=85
I hope this helps and good luck! :)

Answer:
-79.8
Step-by-step explanation:
The change can be found by subracting the ending distance from the beginning distance.
In this case, its 200.6-120.8= 79.8
It is negative because the distance in the end became lower than the beginning distance. 
Hope this helps!
 
        
             
        
        
        
Parallel because they have the same slope. Y+4= -1/2(x-2) is in point slope form, simplified to y intercept form is y=1/2-5... The slope (m) in both equations is the same, if you graphed the equations they would be parallel
