Answer:

Step-by-step explanation:
The basic graph of y = Sin(x), starts at x = 0.
Looking at the graph, the basic sin curve starts at x = π/4
So this function is the parent sin function shifted π/4 units to the right.
<u>Note:</u>
y = Sin(x-a) is the parent function ( y= Sinx) shifted a units right
y = Sin(x+a) is the parent function shifted a units left
<em>Since this function is shifted </em>π/4 units right, the equation would be:
y = Sin (x-π/4)
The third answer choice is right.

Answer:
The constant in the expression is 12
Step-by-step explanation:
The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can be written as :
f(m)=0.05m +12
Example if m is 1 or 2
f(1) = 0.05(1) +12 = 12.05
f(2= = 0.05*2 +12 =0.1 +12 = 12.1
The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.
Answer: 1/6
