Will mark the what are the amplitude, period, phase shift, and midline of f(x) = 2 sin(x + π) − 4?

Step-by-step explanation:

Amplitude is twice the coefficent of the sine function. In this case,

Period is divided by the coefficent of x, in this case,

Phase shift, is how much you sum or subctract from x inside the sine, in this case .

Midline you get by hiding the sine and reading what's left, in this case, -4.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
