Answer:

y= -3

Step-by-step explanation:

(-7/2)y =21/2

Divide both sides by (-7/2) = Multiply by (-2/7)

On the left side ,after cancellation you have only y

On the right side you multiply 21/2 by (-2/7)

y= (21*-2) / 2*7

y=(-42)/14

y=(-21)/7

y=- 3

check:

-(7/2) of- 3 is 10.5 21/2=10.5

Which polynomial is in standard form? A) 26x^5+12x^7-8x^3+6x

Bess [88]

It's C. In order to be in standard form you have to have all your exponents in descending order. They don't all have to be there in order, the ones that are just have to go from highest to lowest.

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%
