Answer:
2/3 = 0.6666666666666667 or just 67%.
Step-by-step explanation:
as you already know, we start off by doing a quick switcheroo on the variables, and then we solve for y to get the inverse,

and if you run a vertical line test on that expression, you'll find that it doesn't pass it, meaning is not a function.
Step-by-step explanation:
first u must find the area of the rectangle.after that,find the area of the square.then you have tu subtract it so that u can get the orange area.
Answer:
0.049168726 light-years
Step-by-step explanation:
The apparent brightness of a star is
where
<em>L = luminosity of the star (related to the Sun)
</em>
<em>d = distance in ly (light-years)
</em>
The luminosity of Alpha Centauri A is 1.519 and its distance is 4.37 ly.
Hence the apparent brightness of Alpha Centauri A is
According to the inverse square law for light intensity
where
light intensity at distance
light intensity at distance
Let
be the distance we would have to place the 50-watt bulb, then replacing in the formula
Remark: It is worth noticing that Alpha Centauri A, though is the nearest star to the Sun, is not visible to the naked eye.
