The radius is the distance from the center point of a circle to the "edge" of the circle. To calculate the circumference you use the formula: C=(D)(pi)...D stands for distance from one end of the circle to the other through the center point - basically the distance is the radius of any circle just doubled.

A line with a slope -2 passes through the point (-1,4). Which equation represents this line in point-slope form?
sesenic [268]

9514 1404 393

Answer:

  y-4 = -2(x+1)

Step-by-step explanation:

The point-slope equation of a line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

You have m = -2 and (h, k) = (-1, 4). Putting these numbers into the above form gives ...

  y -4 = -2(x +1)

You are searching online for techno music that is neither European nor Dutch. In set notation, which set of music files are you
yuradex [85]
<h2>Answer: </h2><h2>Techno ∩ (European ∩ Dutch)'</h2>

Step-by-step explanation:

According to sets theory ;

Intersection ( ∩ ) - e.g (European ∩ Dutch) represents both European and    

                                     Dutch , while (European ∩ Dutch)' represents neither

                                     European nor Dutch .

Union ( ∪ ) - e.g (European ∪ Dutch) represents either  European or Dutch .

So , Techno ∩ (European ∩ Dutch)' represents  set notation of techno musics that is neither European nor Dutch .

A cylindrical vase has a height of 17 in. and a radius of 3in.
steposvetlana [31]
Pi*3^2= 9pi  
pi*6=6pi
6pi*17= 102pi
102pi+9pi= 111pi in. squared

pi*6^2=36pi
pi*12=12pi
36pi+12pi*x=111pi
12pi*x=75pi
x=6.25pi
x=Height btw
