We have to break each degree in terms of 90
A) 
Which is in third quadrant, therefore sine is negative hence
B) 
Which is in third quadrant, therefore cosine is negative hence
C) 
Which is in third quadrant, therefore tangent is positive hence
D) 
Which is in third quadrant, therefore cosec is negative hence
not defined
E)
Which is in third quadrant, therefore secant is negative hence
F) 
Which is in third quadrant, therefore tangent is positive hence
not defined
Hence only 
and
have value -1
Hope this will help
The answer is C I think try putting that one ok I tried to help so yeah um have a great day
Answer:
(x-5)^3
Step-by-step explanation:
(x-5)^3. (x−5)3 ( x - 5 ) 3
Answer:
- geometric sequence with initial value 20 and common ratio 1/2
- average rate of change on [1, 3] = -7.5
Step-by-step explanation:
(a) The given points have sequential values of x and values of y that are each 1/2 the value before. The common ratio tells us the sequence is a geometric sequence.
(b) The first given point is (2, 10), so extrapolating backward, we determine the previous point to be ...
... (2-1, 10/(1/2)) = (1, 20)
Thus, we have enough information to determine the average slope between n=1 and n=3.
... (difference in y)/(difference in n) = (5 -20)/(3 -1) = -15/2 = -7.5
