Answer:

Option B is correct.

The domain of the function h(x) is: \{x | x\neq \pm 6 , x\neq 0\}

Step-by-step explanation:

Domain states that the complete set of all the possible values of the independent variable where function is defined.

Given the function:

h(x) = \frac{9x}{x(x^2-36)}

To find the excluded value in the domain of the function.

equate the denominator to 0 and solve for x.

i.e

x(x^2-36) = 0

⇒x = 0 and x^2-36 = 0

⇒x = 0 and x^2 = 36

or

x = 0 and x = \pm 6

So, the domain of the function h(x) is the set of all real number except x = 0 and x = \pm 6

Therefore, the domain of the function h(x) is:

\{x | x\neq \pm 6 , x\neq 0\}

Answer:

Choice b is correct.

Step-by-step explanation:

We have to find the domain of the given function.

The given function is 9x/x(x²-36).

Domain is the all possible values of x for which the function is defined.

so the function is undefined when x(x²-36) = 0.

So,

x(x²-36) =0

either x = 0 or (x² -36) =0

x=0 or x²= 36

x=0 or x = ±6

So, the domain of function is the set of real numbers except x=0 and x = ±6.

Use identities to find the values of the sine and cosine functions for the following angle measure.
puteri [66]

Using the cosine double angle formula,

\cos 2\theta=2\cos^2 \theta-1=\frac{12}{13}\\\\2\cos^{2} \theta=\frac{25}{13}\\\\\cos^{2} \theta=\frac{25}{26}\\\\\boxed{\cos \theta=\frac{5}{\sqrt{26}}}

(Note I took the positive case since \theta terminates in the first quadrant)

Using the Pythagorean identity,

\sin^2 \theta+\cos^2 \theta=1\\\\\sin^2 \theta+\frac{25}{26}=1\\\\sin^2 \theta=\frac{1}{26}\\\\\boxed{\sin \theta=\frac{1}{\sqrt{26}}}

(Note I took the positive case since \theta terminates in the first quadrant)
