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.
Hello,
8*√3 is the side.
The height is √((8√3)²-(4√3)²)=√(64*3-16*3)=12
Area of the triangle=8*√3*12/2=48√3≈83
Answer: 20 : 3 : 12
Step-by-step explanation:
For every 1 litre, 150 ml of sucrose and 600ml of saline solution is needed.
1litre = 1,000 ml
Water = 1,000 ml
Ratio:
1,000 : 150 : 600
Divide by 50 to get simplest form:
20 : 3 : 12
