What is the midpoint coordinates of segment HX H(13,8) X(-6,-6)

Mathematics
1 answer:
Setler79 [48]4 years ago
7 0
Midpoint of (x1,y1) and (x2,y2) is

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

so the midpoint of HX is the mdpoint of (13,8) and (-6,-6)
which is

(\frac{13-6}{2},\frac{8-6}{2}=
(\frac{7}{2},\frac{2}{2}=
(3.5,1)

the midpoint is (3.5,1)

15. In the rhombus shown below, mz1 = 160°. What are the measures of 22 2 points
egoroff_w [7]

Answers:

angle2 = 160 degrees

angle3 = 10 degrees

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

Explanation:

The two triangles are congruent. We can prove this using SSS. The upper triangle is a mirrored copy of the lower triangle.

Since angle1 = 160 degrees, this means angle2 = 160 also. This is because the corresponding pieces of congruent triangles match up. Or you could use the second part of the hint which says "Opposite angles in a rhombus are congruent".

Let x be the measure of angle 3. For either isosceles triangle, it has congruent base angles measured x degrees. They add to the 160 degrees mentioned earlier to get a total of 180.

160+x+x = 180

2x+160 = 180

2x = 180-160

2x = 20

x = 20/2

x = 10

Angle 3 is 10 degrees.

Un recipiente cilíndrico tiene un diámetro de 160cm. y la misma altura. ¿Cuánto litros de agua puede caber?
Len [333]

Respuesta:

3215360 cm³

Explicación paso a paso:

Dado que :

Radio = 160/2 = 80 cm

Altura, h = 160 cm

Volumen de un cilindro = πr²h

Volumen del cilindro = π * 80² * 160

Volumen = 3215360 cm³

Which sequence of transformations proves that shape I is similar to shape II?
Serhud [2]

Answer:

B. a reflection across X axis and then a dilation by a scale factor of 1.5

Step-by-step explanation:

As clear from the graph all the coordinates of image 2 are 1.5 times of image 1 so shape 2 is dilated by the scale factor 1.5.

It is evident from the graph that lines AO and A"O"are parallel to each other so shape 2 is the reflection of shape 1.

Now we calculate the magnitude of line AB

m1 = (y2-y1)/(x2-x1)

    =(-3+6)/(-4.5=9)

    =3/4.5

    =1/1.5

    =2/3

Next we calculate magnitude m2 of A"B"  

m2= (2-4) /(-3+6)

     =(-2/3)

Then we know Tan(180-∅) = -tan∅

similarly if m1=(-m2)

then the one line having magnitude m2 is the rotated image through X axis by 180° of the line having magnitude m1.

So the answer is B.
