Answer:

  18750

Step-by-step explanation:

The recursive relation describes a geometric sequence with a first term of 6 and a common ratio of 5. The general term will be ...

  an = 6·5^(n -1)

So, the 6th term will be ...

  a6 = 6·5^(6-1) = 6·3125

  a6 = 18750

Answer:

The team lost 9 matches

Step-by-step explanation:

Given

[tex]Matches = 30[/tex]

[tex]Lost = \frac{3}{10}[/tex] of the matches

[tex]Draw = 3[/tex]

Required

Determine the number of matches lost

From the question, we have:

[tex]Lost = \frac{3}{10}[/tex] of the matches

Mathematically, this is:

[tex]Lost = \frac{3}{10} * Matches[/tex]

Substitute 30 for Matches

[tex]Lost = \frac{3}{10} * 30[/tex]

[tex]Lost = \frac{3* 30}{10}[/tex]

[tex]Lost = \frac{90}{10}[/tex]

[tex]Lost = 9[/tex]

The team lost 9 matches

Answer:

a) Escribe un sistema de ecuaciones para representar esta situación.

x + y = 81 ...... Ecuación 1

x - y = 33 ....... Ecuación 2

b) Los dos números son: 57 y 24

Step-by-step explanation:

Estamos tratando con 2 números

Dejar

El primer número = x

El segundo número = y

La suma de dos números es 81.

x + y = 81 ...... Ecuación 1

La diferencia de los mismos dos números es 33.

x - y = 33 ....... Ecuación 2

Escribe un sistema de ecuaciones para representar esta situación.

x + y = 81 ...... Ecuación 1

x - y = 33 ....... Ecuación 2

Resolvemos estas ecuaciones usando el método de eliminación

Restamos la ecuación 2 de la ecuación 1 para eliminar

2y = 48

y = 48/2

y = 24

Resolver para x usando la Ecuación 1

x + y = 81 ...... Ecuación 1

x + 24 = 81

x = 81 - 24

x = 57

Por lo tanto, los dos números son: 57 y 24

Answer:

  (5, 1)

Step-by-step explanation:

Reflection across the x-axis negates the y-coordinate:

  (x, y) ⇒ (x, -y) . . . . reflection across the x-axis

Rotation 90° CCW is the transformation ...

  (x, y) ⇒ (-y, x) . . . . rotation 90° CCW

The two transformations together give ...

  (x, y) ⇒ (y, x) . . . . reflection across the x-axis, then rotation 90° CCW

For point B, this gives ...

  B(1, 5) ⇒ B'(5, 1)

Answer:

78 feet

Step-by-step explanation:

assuming it's the perimeter

25 + 25 + 14 + 14 = 78

The length of the string of the lights is 78 feet.

P = 2(l + w), where 'l' is the length of the rectangle and  w is the width of the rectangle

For given example,

Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a string of light around.

The length of the string of the lights = the perimeter of the rectangular wooden deck

Here, length of the deck (l) = 25 ft.

width of the deck (w) = 14 ft.

Using the formula of the perimeter of the rectangle,

⇒ P = 2 × (l + w)

⇒ P = 2 × (25 + 14)

⇒ P = 2 × 39

⇒ P = 78 ft.

The perimeter of the rectangular wooden deck is 78 feet.

Therefore, the length of the string of the lights is 78 feet.

Answer:

Sam: $30; Bethan: $24

Step-by-step explanation:

Since the ratio is 5:4 Sam has to pay 5/9 of the total which is 54. To find how much he pays set up the equation like this.

[tex]\frac{x}{54} =\frac{5}{9}[/tex]

Cross Multiply

54(5)=9x

270=9x

Divide by 9

30=x

So Sam pays $30. To find out how much Bethan pays simply subtract 30 from 54

54-30=24

So Bethan pays $24

the answer is six

Answer:

f(3)=-11

in other words

When x=3, y=-11

Step-by-step explanation:

f(x)=-3x-2

f(3)=-3(3)-2

f(3)=-9-2

f(3)=-11

Cube Root

[tex] {p}^{3} = 8 \\ p = \sqrt[3]{8} \\ p = \sqrt[3]{ 2\times 2 \times 2} \\ p = 2[/tex]

Formula

[tex] {p}^{3} - 8 = 0[/tex]

Use the following formula.

[tex] {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )[/tex]

[tex](p - 2)( {p}^{2} + 2p + 4)[/tex]

The expression p²+2p+4 has the discriminant less than 0 ( D < 0 ).

Thus, remove the expression and leave only p-2

[tex]p - 2 = 0 \\ p = 2[/tex]

Substitution

The most obvious number that multiplies itself three times and equal 8 is 2.

Substitute p = 2

[tex] {p}^{3} = 8 \\ {2}^{3} = 8 \\ 2 \times 2 \times 2 = 8 \\ 8 = 8[/tex]

The equation is true, thus 2 is the answer.

Answer:

The container can hold 18 gallons

Step-by-step explanation:

Assume the container can hold x gallons

∵ The container is [tex]\frac{2}{3}[/tex]  full with water

∵ It can hold x gallons

→ Multiply [tex]\frac{2}{3}[/tex] by x to find the number of gallons in the container

∴ The number of gallons in the container = [tex]\frac{2}{3}[/tex] x

∵ 4 gallons of water pouring out

∵ It is  [tex]\frac{4}{9}[/tex] full

→ Multiply [tex]\frac{4}{9}[/tex] by x to find the number of gallons left in it

∴ The number of gallons left in the container = [tex]\frac{4}{9}[/tex] x

→ The difference between the numbers of gallons is 4 gallons

∵  [tex]\frac{2}{3}[/tex] x - [tex]\frac{4}{9}[/tex] x = 4

→ Subtract the terms of the left side

∴ [tex]\frac{2}{9}[/tex] x = 4

→ Multiply both sides by 9

∴ 2x = 36

→ Divide both sides by 18

∴ x = 18

∵ x represents the full of the container

∴ The container can hold 18 gallons

Answer:

Step-by-step explanation:

First, lets simplify everything in the parenthesis.

(3×10^​2 ​​ )×(2×10^​−4 ​​ )= ​​

In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.

(3 • 100) • (2 • 1/10^4)

Now, we can just multiply everything from left to right to get:

6*10^-2

Step-by-step explanation:

You can plug any numbers in for x, and solve for y.

Example: 4(-2) + y =20     multiply 4 and -2

                   -8 + y = 20     add 8 to both sides

                          y = 28
