Answer:

-8, -6, -4, -2

Step-by-step explanation:

What is the inverse of y=pi/2+sin x

Alekssandra [29.7K]

Answer:

$f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})$

Step-by-step explanation:

The given function is

$y=\frac{\pi}{2}+\sin x$

To find the inverse of this function, we interchange x and y.

$x=\frac{\pi}{2}+\sin y$

we now solve for y.

$x-\frac{\pi}{2}=\sin y$

Take the sine inverse of both sides to obtain;

$\sin ^{-1}(x-\frac{\pi}{2})=y$

Hence the inverse of the given function is;

$f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})$

where $\frac{\pi}{2}-1\le x\le \frac{\pi}{2}+1$

2) A pool is being filled with a hose. The equation y=12x represents the relationship between

faltersainse [42]

Answer:

Step-by-step explanation:

y = 12x.

A) x=8, so that y = 12(8) = 96. It's on the line

B) x = 10, so that y = 12(10) = 120. It's on the line

C) x = 15, so that y = 15(12) = 180. It's on the line

D) x = 18, so that y = 18(12) = 216, not equal to 206. So, the point is not on the line.
