Select the correct answer. What is the factored form of m6 − 64n3? A. (m2 + 4n)(m4 − 4m2n + 16n2) B. (m − 4n2)(m2 + 4mn2 + 16n4) C. (m + 4n2)(m2 − 4mn2 + 16n4) D. (m2 − 4n)(m4 + 4m2n + 16n2)

Answers

Answer:

Step-by-step explanation:

(m^2- 4n)(m^4+4m^2n+16n^2)

Option D is our correct answer.

i.e (m² - 4n) ([tex]m^{4}[/tex] + 4nm + 16n²).

Given,

[tex]m^{6}[/tex] - 64n³

We need to find the factored form of this.

And select the correct options.

A. (m2 + 4n)(m4 − 4m2n + 16n2)

B. (m − 4n2)(m2 + 4mn2 + 16n4)

C. (m + 4n2)(m2 − 4mn2 + 16n4)

D. (m2 − 4n)(m4 + 4m2n + 16n2)

What is the formula of (a³ - b³)?

It is given as:

( a - b ) ( a² + ab + b² )

Find the factored form [tex]m^{6}[/tex] - 64n³

We can write this as,

[tex](m^{2})^3[/tex] - 4³n³

(m²)³ - (4n)³

This is in the form of (a³ - b³).

Applying this formula.

Now,

(m² - 4n) ((m²)² + 4nm + (4n)²)

(m² - 4n) ([tex]m^{4}[/tex] + 4nm + 16n²)

Thus Option D is our correct answer.

i.e (m² - 4n) ([tex]m^{4}[/tex] + 4nm + 16n²).

si un submarino esta a - 83 metros a nivel del mar, sube a -15 cuantos metros subio?

Answers

Answer:

El submarino subió 68 metros

Step-by-step explanation:

Desplazamiento

Si un cuerpo cambia de posición desde X1 hasta X2, su cambio de posición se calcula como:

X=X2-X1

En el caso de nuestro submarino, su posición original era a X1=-83 m, luego sube a la posición X2=-15 m, así que su cambio de posición o desplazamiento es:

X=-15-(-83)=-15+83=68 m

El submarino subió 68 metros

Answer:

[tex]P(X < 65) = 0.003467[/tex]

[tex]P(86 < X < 110 )= 0.63928 [/tex]

[tex]P(X > 120 ) =0.062024[/tex]

Step-by-step explanation:

From the question we are told that

The mean is [tex]\mu = \$ 100[/tex]

The standard deviation is [tex]\sigma = \$ 13[/tex]

Generally the probability that the monthly utility bills is less than $65 is mathematically represented as

[tex]P(X < 65) = P(\frac{X - \mu }{\sigma } < \frac{65 - 100 }{13 } )[/tex]

Generally

[tex]\frac{X - \mu }{\sigma } = Z (The\ standardized \ value \ of\ X )[/tex]

[tex]P(X < 65) = P(Z < -2.70 )[/tex]

From the z-table

[tex]P(Z < -2.70 ) = 0.003467[/tex]

[tex]P(X < 65) = 0.003467[/tex]

Generally the probability that a randomly selected utility bill is between $86 and $110 is mathematically represented as

[tex]P(86 < X< 110 )= P( \frac{86 -100}{ 13} < \frac{X - \mu}{\sigma } < \frac{86 -100}{ 13} )[/tex]

=> [tex]P(86 < X < 110 )= P( \frac{86 -100}{ 13} < Z < \frac{110 -100}{ 13} )[/tex]

=> [tex]P(86 < X < 110 )= P(-1.08 < Z < 0.77 )[/tex]

=> [tex]P(86 < X < 110 )= P(Z < 0.77 ) - P(Z < -1.08 ) [/tex]

From the z-table

[tex]P(Z < 0.77 ) = 0.77935[/tex]

and

[tex]P(Z < -1.08 ) = 0.14007[/tex]

[tex]P(86 < X < 110 )= 0.77935 - 0.14007 [/tex]

=> [tex]P(86 < X < 110 )= 0.63928 [/tex]

Generally the probability that the monthly utility bills is more than $120 is mathematically represented as

[tex]P(X >120 ) = P(\frac{X - \mu }{\sigma } > \frac{120 - 100 }{13 })[/tex]

=> [tex]P(X > 120 ) = P(Z > 1.538 )[/tex]

From the z-table

[tex]P(Z > 1.54 ) = 0.062024[/tex]

[tex]P(X > 120 ) =0.062024[/tex]

Given ∠A and ∠B are vertical angles with m∠A=20x+10 and m∠B=30x−10 .

What is x?

Enter your answer in the box
PLEASE HELP I APPRECIATE IT

Answers

Answer:

x = 2

Step-by-step explanation:

Vertical angles are equal to each other. It means that,

∠A = ∠B

So,

20x+10 = 30x−10

Taking like terms together, we get :

20x-30x=-10-10

-10x=-20

x=2

So, the value of x is 2.
