Step-by-step explanation:
the solution is found in the images above
Answer is choice C) cosine is even; sine is odd
The properties that come with even and odd functions are...
f(-x) = f(x) indicates we have an even function. So cos(-x) = cos(x)
f(-x) = -f(x) indicates we have an odd function. So sin(-x) = -sin(x)
note: the end result of the proof will lead to cos(A)cos(B)+sin(A)sin(B)
Answer:
The answer is 22!
Step-by-step explanation:
3*5 = 15, 15+7 = 22
Brainliest pls! :D
Exact form: 9/20 and decimal form: 0.45
5 because 20:6 is the car to motorcycle.
6:15 is the motorcycle to van.
20÷15=5
