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:

Step-by-step explanation:

When Maurice works 15hrs, he makes $150.

So first you have to find out how much money he makes each hour.

To do this you do :

Money earnt divided by hour many hours he worked.

Money made per hour = [tex]\frac{150}{15}[/tex]  = $10

So since Maurice makes $10 every hour,

If her works 25 hours, it will be $10 x 25 = ?

Step-by-step explanation:

A.let n be 1

a1=2(1)+3

T1=5

let n be 2

2(2)+3

T2=7

T3=2(3)+3

=9

T4=2(4)+3

=11

A. For the sequence given by the nth term formula an = 2n + 3, the first four terms are:

a1 = 2(1) + 3 = 5

a2 = 2(2) + 3 = 7

a3 = 2(3) + 3 = 9

a4 = 2(4) + 3 = 11

For the sequence given by the nth term formula an = n² - 1, the first four terms are:

a1 = 1² - 1 = 0

a2 = 2² - 1 = 3

a3 = 3² - 1 = 8

a4 = 4² - 1 = 15

B. The missing terms for the sequence 57, 47, 37, 27,  17 are:

57, 47, 37, 27, 17

The missing terms for the sequence -12,-6, , 0, 12, 24, 36 are:

-12, -6, 0, 12, 24, 36

The missing terms for the sequence -4, 8,20, , 16, -20 are:

-4, 8, 20, 16, -20

C. The general rule or nth term for the sequence 7, 12, 17, 22,... is:

an = 5n + 2

The general rule or nth term for the sequence 2, 6, 12, 20,... is:

an = n² + 1

D. The sequence 4, 8, 12, 16,.. is an arithmetic sequence with a common difference of 4.

The sequence 13, 10, 7, 4,... is an arithmetic sequence with a common difference of -3.

The sequence -10, -8, -6, -4,.. is an arithmetic sequence with a common difference of 2.

The sequence 1, 6, 8, 11, 12,.. is not an arithmetic sequence as there is no common difference between consecutive terms.

The sequence 5, 6, 12, 13,... is not an arithmetic sequence as there is no common difference between consecutive terms.

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)

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).

Answer:

  KE = 100 J

Step-by-step explanation:

The question is asking you to use the formula with the values ...

  m = 8 kg . . . . . this 'm' stands for mass

  v = 5 m/s . . . .  this 'm' stands for meters

Putting these values into the formula, we have ...

  KE = 1/2(8 kg)(5 m/s)² = 100 kg·m²/s²

The units are equivalent to the derived SI unit "joules", abbreviated J.

The kinetic energy of the 8 kg mass is 100 J.

Answer:

a

[tex]P(X < 65) =  0.003467[/tex]

b

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

c

[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]

So

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

From the z-table

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

So  

   [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]

So

     [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]

So  

   [tex]P(X > 120 ) =0.062024[/tex]

option C

It will cost $412.50 for equipment for all stations.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard.

The cost will be calculated as below,

3 feet = 1 yard

5 x 30 = 150 feet

8.25 per yard = cost

150/ 3 = 50 yards (total tubing needed)

50 x 8.25 = $ 412.50
