Step-by-step explanation:

The rate of change:

( y2 - y1 ) / (x2 - x1) = ( 18 in - 12 in ) / ( 6 ft - 4 ft ) =

= 6 in / 2 ft = 3 in / 1 ft

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

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