Find the coordinates of the circumcenter for ∆DEF with coordinates D(1,3) E (8,3) and F(1,-5). Show your work.
luda_lava [24]

Answer: The coordinates of the circumcenter is (\frac{9}{2}, -1).

Explanation:

The coordinates of triangle DEF are D(1,3) E (8,3) and F(1,-5).

Distance formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

DE=\sqrt{(8-1)^2+(3-3)^2}=7

FE=\sqrt{(1-8)^2+(-5-3)^2}=\sqrt{7^2+8^2}

DF=\sqrt{(1-1)^2+(-5-3)^2}=8

Since triangle follows pythagoras theorem,

(DF)^2+(DE)^2=(FE)^2

Therefore the given triangle is a right angle triangle.

Or plot these points on a coordinate plane. From the figure we can say that the triangle DEF is a right angle triangle.

The circumcenter of a right angle triangle is the midpoint of the hypotenuse.

The hypotenuse is EF. The midpoint of EF is,

Midpoint =(\frac{8+1}{2}, \frac{3-5}{2} )=(\frac{9}{2}, -1)

Therefore, the coordinates of the circumcenter is (\frac{9}{2}, -1).

of the 35 largest cities in a country, 4 are located in state A. If state A has twice as many large cities as state B, how many
Hunter-Best [27]

State A has 4/35 of the largest cities in the country.

A has twice as many largest cities in the country than State B does.

This means State B has 2/35 of the largest cities in the country.

The average of 8,6,9,12 and 4x is x. What is the value of x
Juliette [100K]
8 + 6 + 9 + 12 + 4x / 5  =  x                      Original Problem.
25 + 4x / 5 = x                                         Addition.
25 + 4x = 5x                                            Multiply each side by 5.
25 = x                                                      Subtract 4x from each side.
x = 25                                                      Switch equation around.

Answer: x = 25
