What is the reference angle in degrees for 31π 6 ?

Mathematics

padilas [110]3 years ago

Okay - so 12pi/6 = 360. We need to make 31pi/6 between 0pi/6 and 12pi/6 in order to obtain the reference angle. So let's do that.


31pi/6 - 12pi/6 = 19pi/6

19pi/6 - 12pi/6 = 7pi/6


The reference angle in radians is 7pi/6, but it wants degrees - so we convert to degrees using 180/pi.


7pi/6 * 180/pi = 210 degrees

Which simplified equation is equivalent to the equation shown below?<br> 9 +6X+2x-1= 24
Serhud [2]

Answer:

B  8+8x = 24

Step-by-step explanation:

9+6x+2x-1 = 24

Combine like terms

6x+2x   +9-1 = 24

8x +8 = 24

Rearranging

8 + 8x =24

Use a table of values to find the solution to the equation f(x)=h(x) where
GuDViN [60]

9514 1404 393

Answer:

  x = 2 1/3

Step-by-step explanation:

We can examine the equations to see where the solution lies.

<u>f(x) = (2/3) -x</u>

This has an x-intercept where y=0, at x=2/3. It has a y-intercept where x=0, at y=2/3. Its slope is -1.

<u>h(x) = 3 -2x</u>

This has an x-intercept where y=0, at x=3/2. It has a y-intercept where x=0, at y=3. Its slope is -2.

__

In the first quadrant, the graph of h(x) is farther from the origin and steeper than the graph of f(x). The lines must cross in the 4th quadrant at some value of x that is greater than 3/2. The fraction in the definition of f(x) suggests that the solution will be a multiple of 1/3.

The attached table shows a couple of guesses at values of x that would make f(x) = h(x). We find that x = 7/3 is the solution we're looking for.

<em>Additional comment</em>

Repetitive function evaluations are done conveniently and with fewer errors by a calculator or spreadsheet that can work with tables of values. Here, we have used a graphing calculator. These tools are readily available for free on almost any phone, tablet, or desktop computer platform.
