Can somebody help me??

Answer:

A y C: paralelas

B y A: perpendiculares

B y C: perpendiculares.

Step-by-step explanation:

Sea una recta:

f(x) = a*x + b

Donde a es la pendiente y b es la ordenada al origen.

Otra recta va a ser paralela a esta si tiene la misma pendiente, pero una diferente ordenada al origen, por ejemplo:

g(x) = a*x + c

Y una recta perpendicular a f(x) tendría una pendiente p = -(1/a)

Entonces podemos escribir la línea perpendicular a f(x) como:

h(x) = -(1/a)*x + c

Ahora veamos nuestras líneas:

A(x) =  y = −3*x+5

B(x) = y = x/3+2 = (1/3)*x + 2

C(x) = y = -3*x + 1

Primero veamos cuáles son paralelas:

A(x) y C(x) tienen la misma pendiente (-3) y diferente ordenada al origen, entonces  A y C son paralelas.

Sabiendo que la pendiente de A y C es -3, una línea perpendicular a esta tendría una pendiente:

-(1/-3) = 1/3

Que es justamente la pendiente que tiene la línea B, entonces podemos concluir que B es perpendicular a las líneas A y C.

A y C: paralelas

B y A: perpendiculares

B y C: perpendiculares.

to solve for x. So, x = 4 and y = 3. COORDINATE GEOMETRY Graph each quadrilateral with the given vertices. Determine

Answer:

n = 6[tex]\sqrt{3}[/tex]

Step-by-step explanation:

you can create this proportion:

18/n = n/6

cross-multiply:

n² = 108

n = [tex]\sqrt{108}[/tex]

[tex]\sqrt{108}[/tex] = [tex]\sqrt{4}[/tex]·[tex]\sqrt{9}[/tex]·[tex]\sqrt{3}[/tex] = 2·3·[tex]\sqrt{3}[/tex] or 6[tex]\sqrt{3}[/tex]

Answer:

a) 101°

Step-by-step explanation:

arc HK = 2(39.59°) = 79.18°

arc JH = 180°

arc JK = 360° - 180° - 79.18° = 100.82°

JK = 101°

The correct answer is option (A) 101°

"It is an angle in a circle formed by two chords that have a common end point on the circle."

For given example,

m ∠J = 39.59°

We know, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.

⇒ m(∠J) = (1/2) × arc KH

⇒ arc KH = 2 × 39.59°

⇒ arc KH = 79.18°

Also, arc HJ = 180°

We know for given figure,

⇒ arc JK + arc KH +arc HJ = 360°

⇒ arc JK + 79.18° + 180° = 360°

⇒ arc JK + 259.18° = 360°

⇒ arc JK = 100.82°

⇒ mJK ≈ 101°

Therefore,  mJK = 101°

The correct answer is option (A) 101°

(c) and (e)

Step-by-step explanation:

Given

[tex]Pr = \frac{2}{3}[/tex]

Required

Which 2 options can be used to simulate the given probability.

The two options are (c) and (e)

The proof is as follows;

Option (c)

We have:

[tex]Rolls = 7[/tex]

A cube has 6 faces. So:

[tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(S)=6[/tex]

The probability of getting ones, twos, threes, and fours is:

[tex]Pr = \frac{n(1,2,3,4)}{n(S)}[/tex]

In: [tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(1,2,3,4) = 4[/tex]

So:

[tex]Pr = \frac{4}{6}[/tex]

Simplify

[tex]Pr = \frac{2}{3}[/tex]

Option (e)

We have:

[tex]White = 10[/tex]

[tex]Red = 5[/tex]

[tex]Count = 7[/tex]

Record the probability of white.

This is calculated as:

[tex]Pr = \frac{White}{Total}[/tex]

[tex]Pr = \frac{White}{White + Red}[/tex]

[tex]Pr = \frac{10}{10+5}[/tex]

[tex]Pr = \frac{10}{15}[/tex]

Simplify

[tex]Pr = \frac{2}{3}[/tex]

Answer:

In the first one answer is r²

In second one answer is 3

Step-by-step explanation:

Yes it is Algebra with different powers

In first one (6r4+4r) +(__- 2r4 + 3r) = 4r4 + r2 + 7r

Like terms are added:

6r^4- 2r^4 + 4r  + 3r +____ = 4r^4 + r2+ 7r

4r^4+7r +___ = 4r^4 + r^2 + 7r

Therefore ___ = r^2

In second one:

(__ -8x - x^2)-(4x^2 -7 +6x) = -5x^2 +14x +10

Open the brackets

__  -8x - x^2-4x^2 +7 -6x = -5x^2 +14x +10

Add like terms

__ -14x -5x^2  + 7=  -5x^2 +14x +10

Therefore

___ + 7 = 10

___ = 10 -7 = 3

Answer:

The volume of the cylinder is equal to 1205.76 cubic units.

Step-by-step explanation:

Given that,

Height of the cylinder, h = 6

Radius of the cylinder, r = 8

We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\V=3.14\times 8^2\times 6\\\\V=1205.76\ units^3[/tex]

So, the volume of the cylinder is equal to 1205.76 cubic units.

Total Number of red balls = 5

Total Number of blue balls = 5

Total Number of white balls = 7

Number of red balls selected = 3

Number of blue balls selected = 4

Number of red balls selected = 5

Using the multiplication and combination relation :

nCr * nCr * nCr

Red balls = 5C3

Blue balls = 5C4

White balls = 7C5

Using calculator:

5C3 * 5C4 * 7C5 = 10 * 5 * 21
