I don't understand cuz it only goes to 10
Answer:
<h3>
f(x) = x - 6</h3><h3>
g(x) = x - 5</h3>
Step-by-step explanation:
You will need 28 rows because if you divide 224 by 8 you would get 28 (:
Hi there!
We are given:
cos(7x)cos(4x) = -1 - sin(7x)sin(4x)
Begin by moving all terms with variables to one side:
cos(7x)cos(4x) + sin(7x)sin(4x) = -1
The corresponding trig identity is cos(A - B). Thus:
cos(7x - 4x) = cos(7x)cos(4x) + sin(7x)sin(4x) = -1
cos(3x) = -1
cos = -1 at π, so:
3x = π
x = π/3
We can also find another solution. Let 3π = -1:
3x = 3π
x = π
Thus, solutions on [0, 2π) are π/3 and π.
The answer is 2/3
I hope this works for you :)
