Find the equation of a line that is perpendicular line to y = 10x - 45 and goes through (1, 1).
Airida [17]

The line y = 10x - 45 is already written in the y = mx+q form. This means that m is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.

So, our perpendicular line has a slope of -\frac{1}{10}

Finally, we want a line passing through (1,1) with slope -\frac{1}{10}:

y-1 = -\dfrac{1}{10}(x-1) \iff y = -\dfrac{x}{10} + \dfrac{1}{10}+1 = -\dfrac{x}{10} + \dfrac{11}{10}

A cylindrically shaped space station is rotating about the axis of the cylinder to create artificial gravity. The radius of the
erica [24]

Answer:

8%

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%

4x - 2 (x-2) = -4 + 5x -13
kolezko [41]

Answer:

x = 7

Step-by-step explanation:

Given

4x - 2(x - 2) = - 4 + 5x - 13 ← distribute left side and simplify

4x - 2x + 4 = 5x - 17

2x + 4 = 5x - 17 ( subtract 5x from both sides )

- 3x + 4 = - 17 ( subtract 4 from both sides )

- 3x = - 21 ( divide both sides by - 3 )

x = 7
