What is the reference angle for 11pi/6? Explain your thinking.

il63 [147K]

First we need to see in which quadrant 11pi/6 lies And it lies in fourth quadrant. And to find the reference angle in the fourth quadrant, we need to subtract the given angle from 2 pi . For e.g if the angle is 5pi/3, then the reference angle is 2pi - (5pi/3) = pi/3 .

So for the given question, reference angle of 11pi/6 is

$2 \pi - \frac{11 \pi}{6} = \frac{ \pi}{6}$

And that's the required reference angle .

Find f(x) and g(x) so the function can be expressed as y = f(g(x)). (1 point)

Rina8888 [55]

Answer:

$g(x)=x^2+4$ and $f(x)=\frac{8}{x}$

Step-by-step explanation:

If we want to express $y$ as $y=f(g(x))$ , this means that put the function $g(x)$ into $x$ of $f(x)$ to get $y$ .

The function $y$ is given as $y=\frac{8}{x^{2}+4}$

<u>So we need to figure out a function $g(x)$ that we can put into another $f(x)$ to get $y$ </u>

If we let $g(x)=x^2+4$ and $f(x)=\frac{8}{x}$ , we can clearly see that putting g(x) into x of f(x) will give us $\frac{8}{x^2+4}$ , which is y.

Hence $g(x)=x^2+4$ and $f(x)=\frac{8}{x}$
