The table below shows the depth of a hole as it is dug over time.
time depth
(minutes) (inches) |
4.5
6 | 9.0
9
12.5 |
15 20.0
36.0
was the hole dug at a constant rate? if so, what is the constant of proportionality?
if not, how do you know the rate of digging was not constant? (asap)

one that is bigger than 3 1/2

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: (3,11) is your answer.
