Answer:
Step-by-step explanation:
note : (ax)' = a
(b)' = 0
f(x) = x-5. so : f'(x) = 1
Answer: A.
Step-by-step explanation:
1/4 is not in fact a natural number, it's a rational number, a ratio.

Answer: Choice C</h3>
cos(a - b) = cos(a)cos(b) + sin(a)sin(b)
In this case, we'd have a = 180 and b = q, so,
cos(a-b) = cos(a)cos(b) + sin(a)sin(b)
cos(180 - q) = cos(180)cos(q) + sin(180)sin(q)
cos(180 - q) = -1*cos(q) + 0*sin(q)
cos(180 - q) = -cos(q) + 0
cos(180 - q) = -cos(q)
