The measure of angle θ is 3pi/2 . The measure of its reference angle is /, and tan θ is .

Sphinxa [80]

Answer:

Reference angle: $\frac{\pi}{2}$

$tan(\theta)=tan(\frac{3\pi}{2})$ is not defined.

Step-by-step explanation:

The angle $\theta$ goes from the positive x-axis to the negative y-axis.

Therefore the reference angle can be calculated as following:

$\frac{3\pi}{2}-\pi=\frac{\pi}{2}$

We know that $tan(\theta)$ is:

$tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

If $\theta=\frac{3\pi}{2}$ then $cos(\frac{3\pi}{2})=0$ , therefore $tan(\frac{3\pi}{2})$ is not defined, because the division by 0 is not defined.

Choose a fraction that makes the following sentence true. 0.1 is a rational number because it can be written as ___.

pychu [463]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

0.1 is a rational number because it can be written as $\dfrac{p}{q}$ form.

So, we can write it as

$0.1=\dfrac{0.1}{1}\\\\=\dfrac{0.1\times 10}{1\times 10}\\\\=\dfrac{1}{10}$

so, it can be written as $\dfrac{1}{10}$

Hence, option 'a' is correct.
