Answer:
[tex]D=0.400[/tex]
Step-by-step explanation:
Basic trigonometric functions have the following formula:
[tex]f(x)= A. trig.(Bx-C)+D[/tex]
Where:
[tex]A=amplitude\\trig= basic trigonometric function (sin or cos)\\B and C= phase shift\\D=vertical shift[/tex]
So D is the number that goes adding or resting at the formula's end. In this case:
[tex]D=0.400[/tex]
