omeli [17]

Answer:

  • circumscribed circle
  • The center of a circle circumscribing the triangle connecting the 3 cities will be equidistant from all three cities.

Step-by-step explanation:

The circumscribed circle or <em>circumcircle</em> of a polygon is a circle that passes through all the vertices of the polygon. The center of the circle, the circumcenter, is equidistant from all of the polygon's vertices.

The center is found at the point of intersection between the perpendicular bisectors of any two (non-parallel) chords of the circle. That is, <em>the perpendicular bisectors of any two of the sides of the triangle joining the cities will intersect at the circumcenter</em>.

The method of locating the center of the circle this way is simple and effective.

1. Let the sample space represent all the values from 1 to 10. Let A = {1, 2, 8} and B = {2, 7}. What is the P(A ∩ B)?
AnnZ [28]

A \cap B denotes to all common elements in both A and B

  • Sample space=S={1,2,3,4,5,6,7,8,9,10}

So

  • A={1,2,8}
  • B={2,7}

2 is common

Hence

A $\cap$ B={2}

Solve by adding or subtracting.<br> x+y=-10<br> 2x-y=-8
riadik2000 [5.3K]

Answer:

x=-6\\y=-4

Step-by-step explanation:

To solve, isolate your first equation for y.

x+y=-10\\y=-x-10

Now, plug in this y value to your second equation.

2x-(-x-10)=-8\\2x+x+10=-8\\3x+10=-8\\3x=-18\\x=-6

Now, plug your x value into your first equation and solve for y.

-6+y=-10\\y=-4
