What is the midpoint of a segment with endpoints at (−4, −8) and (8, 10)? A.(−6, −9) B.(−6, 1) C.(2, −9) D.(2, 1)

spayn [35]

$\text{The formula of the midpoint of segment AB:}\\\\\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right).\\\\\text{We have the points}\ A(-4,\ -8)\ \text{and}\ B(8,\ 10).\ \text{Substitute:}\\\\x=\dfrac{-4+8}{2}=\dfrac{4}{2}=2\\\\y=\dfrac{-8+10}{2}=\dfrac{2}{2}=1\\\\Answer:\ \boxed{D.\ (2,\ 1)}$

My friend recently proved 0=1 and i know something is wrong but i dont know what

konstantin123 [22]

Step-by-step explanation:

Remember when expanding radicals,

$\sqrt{ab} = \sqrt{a} \times \sqrt{b}$

When expanding radicals into two radicals, we don't let our radicand have two negative answers.

$i = \sqrt{ - 1}$

${i}^{2} = - 1$

We don't do this

$(\sqrt{ - 1} ) {}^{2} = \sqrt{ - 1 \times - 1}$

$- 1 = \sqrt{1}$

$- 1 = 1$

Recent study of alcohol drinking practices among college students found that the average number of drinks per week consumed was

VashaNatasha [74]

Answer:

A

Step-by-step explanation:

Here as we can see that minimum drink a person can drink is 0 and is

(3.5-0)/2 =1.75 std deviation away from mean

which reflects that distribution;s right tail is more extended

therefore option A is correct: Distribution is right skewed

Enter a range of value for x.

zubka84 [21]

Answer:

-2 < x < 35

Step-by-step explanation:

We have that the larger side has a larger opposite angle and the smaller sides and a smaller opposite angle.

The opposite angle of the 14 unit side is 37 °.

The opposite angle of the 13-unit side is (x + 2) °.

Since 13 <14, it would be:

x + 2 <37

we subtract 2 on both sides

x <35

The value of x must be less than 35.

Now, to form a triangle, the angle must be greater than 0.

x + 2> 0

we subtract 2 on both sides

x> -2

The value of x must be greater than - 2.

Therefore the answer would be:

-2 <x <35

Las llantas de un automóvil pequeño tiene una medida de 14 pulgadas de diámetro.Realiza la gráfica de una de las llantas colocan

LiRa [457]

Answer:

Invitamos cordial a revisar la imagen adjunta abajo para mayor detalle sobre la gráfica de las llantas.

La forma general de la circunferencia de la llanta está representada por $x^{2}+y^{2}-49 = 0$ .

Step-by-step explanation:

A continuación, anexamos una representación de las llantas del automóvil como una circunferencia centrada en el origen y con un diámetro de 14 pulgadas, es decir, un radio de 7 pulgadas.

La ecuación estándar de la circunferencia centrada en un punto dado y con un radio determinado está definida por:

$(x-h)^{2}+(y-k)^{2} =r^{2}$ (1)
