Answer:

b=\frac{1}{6}

Step-by-step explanation:

In f(x)=a\cos(b(x-c))+d, b represents a constant related to the period of the function. Here's how it's related:

b=\frac{2\pi}{T}, where T is the period of the function.

We're given T=12\pi, so solving for b:

b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}

Is x=4 and y=5 perpendicular
faltersainse [42]

True!

<h2>Explanation:</h2>

The Cartesian coordinate system is formed by two perpendicular axes, which are the x-axis and y-axis. In this problem, we are given two lines:

x=4 \ and \ y=5

  • The line x=4 is parallel to the y-axis and has an undefined slope.
  • The line y=5 is parallel to the x-axis and has a slope of zero.

Since the x and y-axes are perpendicular, then the lines x=4 \ and \ y=5 are also perpendicular.

Gwar [14]
2 divides both numbers, so divide both numbers by 2 to get 3 and 7. These are relatively prime, so 2 is the gcd. The lcm is 6*14/2=42.
