Mhanifa please help! Find the coordinates of the circumcenter of the triangle with the vertices A(4, 12), B(14, 6), and C(-6, 2)
melamori03 [73]

Answer:

  • (4.5, 1.5)

Step-by-step explanation:

<u>Given vertices of a triangle:</u>

  • A(4, 12), B(14, 6), and C(-6, 2)

Let the circumcenter is point M(x, y)

We know that the circumcenter is equidistant from each of the vertices.

<u>Use distance formula:</u>

  • AM = √(x - 4)² + (y - 12)²
  • BM = √(x - 14)² + (y - 6)²
  • CM = √(x + 6)² + (y - 2)²

<u>All three distances are equal:</u>

  • AM = BM = CM ⇒ AM² = BM² = CM² ⇒
  • (x - 4)² + (y - 12)² = (x - 14)² + (y - 6)² = (x + 6)² + (y - 2)²

<u>Square of each:</u>

  • AM² = x² - 8x + 16 + y² - 24y + 144 = x² + y² - 8x - 24y + 160
  • BM² = x² - 28x + 196 + y² - 12y + 36 = x² + y² - 28x - 12y + 232
  • CM² = x² + 12x + 36 + y² - 4y + 4 = x² + y² + 12x - 4y + 40

<u>Comparing the squares, we get following system:</u>

  • -8x- 24y + 160 = -28x - 12y + 232 ⇒ 20x - 12y = 72 ⇒ 5x - 3y = 18
  • - 8x - 24y + 160 = 12x - 4y + 40 ⇒ 20x + 20y = 120 ⇒ x + y = 6

<u>Solve by substitution, x = 6 - y:</u>

  • 5(6 - y) - 3y = 18
  • 30 - 8y = 18
  • 8y = 12
  • y = 1.5

<u>Find x:</u>

  • x = 6 - 1.5 = 4.5

So the circumcenter is M(4.5, 1.5)

Need help pls will give you five stars
Temka [501]

Answer:

\boxed{A. (1,1)}

Step-by-step explanation:

Well since in,

f(x) = -3x^2 + 6x - 2

the 3x^2is negative that means the parabola has a maximum not a minimum meaning we can take out choices,

B and D.

To find the maximum let’s graph the given equation,

Look at the image below.

By looking at the image we can tell that the maximum is at (1,1).

So the answer is choice A (1,1)
