15. Simplify sin(90° - O) cos 0 - sin(180° +0) sin e.​
dalvyx [7]

Answer:  cos²(θ) + sin(θ)sin(e)

<u>Step-by-step explanation:</u>

sin (90° - θ)cos(Ф) - sin(180° + θ) sin(e)

Note the following identities:

sin (90° - θ) = cos(x)

sin (180° + θ) = -sin(x)

Substitute those identities into the expression:

   cos(x)cos(x)  -  -sin(x)sin(e)

=  cos²(x) + sin(x)sin(e)

Which is an appropriate domain for the function A?
dolphi86 [110]

B, because the height of the boys can be anywhere between any positive number, however not negative because you can't be a negative height.

D, its is non-linear because their heights won't be going up by the same amount each time your x-value increases because the human body grows at different rates, it will be increasing because the human body is always growing until death.
