using modular arithmetic we take the mod 3 and mod 8 at both sides we find that y=1(mod3) and x = o (mod 8)
Answer:
A. x + 9
Step-by-step explanation:
x² + 5x - 36 = (x + 9) (x - 4)
Answer:
frequency = 1/(2π)
Step-by-step explanation:
The frequency of the function is found by comparing the argument of the cosine function to (2πfx), where f is the freuqency.
2πfx = x . . . . the argument of the cosine is x in f(x)=2cos(x) -4
2πf = 1 . . . . . . divide by x
f = 1/(2π) . . . . . the frequency of the function f(x)
