Answer: y=(x-1)/2

Step-by-step explanation:

To find the inverse, you want to switch the y with x and x with y. Then, you solve.

y=2x+1 [switch y with x and x with y]

x=2y+1 [subtract both sides by 1]

x-1=2y [divide both sides by 2]

(x-1)/2=y

Now, we know that y=(x-1)/2 is the inverse.

A cylindrically shaped space station is rotating about the axis of the cylinder to create artificial gravity. The radius of the

erica [24]

Answer:

Step-by-step explanation:

The maximum change happens when all 500 people moves form outer surface to the station center. When all of them are at the surface, the total moment of inertia is:

$I = I_s + 500I_p = 3*10^9 + 500m_pr_p^2=3*10^9 + 500*70*82.5^2=3.24*10^9$

When they are at the axis, the total moment of inertia is only the station's, which is $3*10^9$

By the law of angular momentum conservation:

$I_1\omega_1 = I_2\omega_2$

$\omega_2/\omega_1 = I_1/I_2 = \frac{3.24*10^9}{3*10^9} = 1.08$

So the angular speed changes by 0.08 of itself, or 8%
