Brainliest for help! <br> Sketch a graph of the function <br> y =sin(x) + 2
diamong [38]

Answer:

The parent sine graph y=sin(x) has a range of -1 ≤ y ≤ 1

It crosses the x-axis x = 0° ± 180°n

The maximum points occur when x = 90° ± 360°n and y = 1

The minimum points occur when x = 270° ± 360°n and y = -1

The sketch the graph of function y=sin(x)+2 we simply move the graph of y=sin(x) up 2 units.

So this means it will have a range of 1 ≤ y ≤ 3

It no longer crosses the x-axis.

The maximum points occur when x = 90° ± 360°n and y = 3

The minimum points occur when x = 270° ± 360°n and y = 1

<u>Attached diagram</u>

The parent function y=sin(x) is shown in grey (dashed line)

The function y=sin(x)+2 is shown in red.

Somebody please help!!!!!!!!
Jlenok [28]

Answer:

I think the answer is b^2=8^2-4^2

Step-by-step explanation:

The equation is A^2+B^2=C^2

C^2-A^2=B^2

C^2-B^2=A^2

C is the hypotenuse. You know what a is and all you have to do is show the equation
