we know that
The circumcenter of a triangle is the point where the perpendicular bisectors of the sides intersect. It is also the center of the circumcircle, the circle that passes through all three vertices of the triangle
The distance of the circumcenter to the vertices of the triangle is equal to the radius of the circle
<u>see the attached figure to better understand the problem</u>
therefore
<u>the answer is</u>
The cell phone company must be place the new cell tower in the circumcenter of the triangle formed by the center of the three towns
Answer:
Hi! I can't really see the graphs on the picture but i can tell you what it should looks like, The graph opens up which means it makes a U shape and The vertex is (- , -
) the Axis of Symmetry is x = -
and, if you can find all those points in your graph then you'll get 100% i'm sorry that i can't see the picture but i can see the shape but i also need to see the Units.

Step-by-step explanation:
Given : she must mix a solution of 67% herbicide with a solution of 46% herbicide to form 42 liters of a 55% solution.
To Find: How much of the 67% solution must she use?
Let x = amount of 67% solution needed
Then 42-x=amount of 46% solution needed
Now we know that the pure herbicide in the 67% solution
So, pure herbicide = (0.67x)
The amount of pure herbicide in the 46% solution (0.46(42-x))
Now 42 liters of a 55% solution = (0.46(42-x))
So,
Amount of 67% solution + Amount of 46% solution = 42 liters of a 55% solution
⇒0.67x+0.46(42-x)=0.55*42
⇒0.67x+19.32-0.46x=23.1
⇒0.21x=3.78
⇒
⇒x = 18 liters
Hence she use 18 liters of the 67% solution
