Answer:

In order for the tower to have an equal distance from each center, the company must find which point is equidistant from the vertices of the triangle. This will be the circumcenter of the triangle. This can be found through constructing the point of concurrency of the perpendicular bisectors the triangle has.

Step-by-step explanation:

This is pretty much the sample response but I rephrased it. :D

Answer:

The middle of the triangle.

Step-by-step explanation:

If the 3 towns each have a highway connecting the center of each town then you place it in the middle of the triangle.  Which would be equadistant from each of the centers of the town.

Find the x-intercept of the parabola of with vertex (1,20) and the y-intercept (0,16). write your answer in this form: (x1,y1),(
svetoff [14.1K]
I assume that the parabola in this particular problem is one whose axis of symmetry is parallel to the y axis. The formula we're going to use in this case is (x-h)2=4p(y-k). We know variables h and k from the vertex (1,20) but p is not given. However, we can solve for p by substituting values x and y in the formula with the y-intercept:

(0-1)^2=4p(16-20)

Solving for p, p=-1/16.

Going back to the formula, we can finally solve for the x-intercepts. Simply fill in variables p, h and k then set y to zero:

(x-1)^2=4(-1/16)(0-20)
(x-1)^2=5
x-1=(+-)sqrt(5)
x=(+-)sqrt(5)+1

Here, we have two values of x

x=sqrt(5)+1 and
x=-sqrt(5)+1

thus, the answers are: (sqrt(5)+1,0) and (-sqrt(5)+1,0).

What is the molarity of a solution
Vika [28.1K]

Answer:

0.670. M

Step-by-step explanation:

Molarity can be expressed like this:

molarity =  number of moles /volume (L)

We know the volume, which is  2.37 L , but we need to find the number of moles. We can do this by dividing  67.3 g  by the molar mass of  L i C l :

number of moles  = mass of sample /molar mass

number of moles  =  67.3 g /(6.94 + 35.45) g/mol  = 67.3 g /42.39 g/mol

number of moles = 1.59 mol

molarity = 1.59 mol /2.37 L =  0.670. M

6. Find the value of r in the following triangle.
makkiz [27]

Answer:

r = 19.2deg

Step-by-step explanation:

6r + 5 = 30 + 90 (exterior angles of a triangle)

6r = 115

r = 19.2deg (1dp)
