Answer: It is not a Function
Step-by-step explanation: One input has two outputs.
Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is
or 1/9 to the 3rd power.
<em>Down is a formula I made!</em>
Main number: 1/9
Repeating how many times: 3
Expression: 
Therefore, 1/9 to the 3rd power is 1/729.

<em>Note: The questioner did not ask for the answer. I wanted to add it anyway for future reasons.</em>
The answers are 115 remainder 2 & 135
<span>the sum of three consecutive integers is three times the second integer. Set up an equation that models this statement and show by solving the equation, that this equation will always be true for any three consecutive integers </span>
Find length CD first, which is the hypotenuse of the triangle.
PD = opposite
Opposite & hypotenuse = SOH or sin
Sin(27) = 15/H
x h, then ÷ sin(27)
H = 15/sin(27)
H = 33.04....
Move to triangle CDR:
15 is length opposite the angle we're after.
So far, we've got the hypotenuse (which we just found to be 33.04....) & the opposite of our triangle
Hypotenuse & opposite = SOH
Sin(x) = 15/33.04... but, to find the angle we do inverse of sin
sin-1(15/33.04...) = x
x = 27
(33.04... means I used the full numbers displayed on my calculator)
Thus, RCD is 27 degrees
Hope this helps!
