Answer:

The correct options are 1, 3 and 6.

Step-by-step explanation:

Circumcenter of a triangle:

1. It is the intersection point of perpendicular bisector of at least two sides of the triangle.

2. It is the center of the circle that passes through all vertices of the triangle.

It is given that the H Is the circumcenter or a triangle DEF. It means H is the center of the circle that passes through the points D,E,F.

Option 1 is correct.

HD,HE and HF are radius of the circle,

$HE\cong HD$

Option 3 is correct.

$\angle DLH\cong FNH=90^{\circ}$

Option 6 is correct.

Therefore the correct options are 1, 3 and 6.

Triangle ABC has vertices at A(1,2) B(4,6) and C(4,6) in the coordinate plane. The triangle will be reflected over the x-axis an

k0ka [10]

You should know that you can predict changes in coordinates after translations without a graph or anything like that.

(x, y) reflected over the x axis = (x, -y)
(x, y) reflected over the y axis = (-x, y)
(x, y) rotated 90 degrees around the origin = (y, -x)
(x, y) rotated 180 degrees around the origin = (-x, -y)
(x, y) rotated 270 degrees around the origin - (-x, y)

So here's our set of points.
A(1, 2), B(4, 6), C(4, 6)

Here's those points reflected over the x axis.
A'(1, -2), B'(4, -6), C'(4, -6)

And here's those points rotated 180° around the origin.
A''(2, -1), B''(6, -4), C''(6, -4)

I think you made a mistake writing down the question, though, because B and C are the same yet you say ABC forms a triangle. You should be able to go through this process with whatever the coordinate was supposed to be.

A gardener has 27 pansies and 36 daisies. he plants an equal number of each type of flower in each row. what is the greatest pos

VikaD [51]

I just did this is our math book at school, but what you do is find the GCF of the numbers. So list all there factors. 27=1x27, 3x9, and that's it. 36=1x36, 2x18, 3x12, 4x9, and that's it. So, next you see that highest numbers they both have in common, in this case it is 9. So your answer is, 9 pansies.

What is 129.392 rounded to nearest Ten?

Stels [109]

$\huge\bold\color{purple}{Answer:}$

====================================

Explanation:

To round 129.392 to the nearest tenth consider the hundredths’ value of 129.392, which is 9 and equal or more than 5. Therefore, the tenths value of 129.392 increases by 1 to 4.

129.392 rounded to the nearest tenth = 129.4
