Y = 5sin (2x) + 4 What's the amplitude, period, phase shift, and vertical shift?

Mathematics

       Y = 5 sin(2x) + 4

The amplitude of the sin itself is 1 .
The amplitude of 5sin is 5 .

Every time the "argument" of the sin increases by 2π
another period starts.
The first period goes from zero until  2x = 2π .
So the length of the period is π .

The phase shift is the value of the angle when x=0.
That's zero.

The sin itself wiggles up and down, regularly and symmetrically,
above and below the x-axis (y=0).  In this equation, the whole thing
is shifted up 4 units by that +4 on the end, so it's wiggling up and down
above and below the line y=4.  The vertical shift is +4 .

If this function were an electrical signal, we would say that its
period is π seconds, its frequency is 1/π Hz, and it has an
AC amplitude of 5 riding on a DC component of 4 .

Find the surface area of each rectangular prism given its length, width, and height. Choose the correct answers.
Jet001 [13]
To answer this question we have to go through each answer, and use this equation:
(a = area, w = width, l = length, h = height)
a=2(wl+hl+hw)
to solve, and see if it's correct.

A) a=2(9·4+3·4+3·9) = 150
<span>Correct!

</span>B) a=2(3·7+4·7+4·3) = 122
Incorrect.

C) a=2(5·8+5·8+5·5) = 210
Incorrect.

D) a=2(7·5+6·5+6·7) = 214
Correct!

The correct answers are A, and D. 

Hope this helped! Please comment or DM me if you have anymore questions. :)
