Question

Need help ASAP! Not D!

Answer 1

`D=0.400`

Explanation:

Basic trigonometric functions have the following formula:

`f(x)= A. trig.(Bx-C)+D`

Where:

`A=amplitude\\trig= basic trigonometric function (sin or cos)\\B and C= phase shift\\D=vertical shift`

So D is the number that goes adding or resting at the formula's end. In this case:

`D=0.400`
