Is this a function: No, this is not a function because the input values are not uniquely mapped to the output values.

In Mathematics and Geometry, a function can be defined as a mathematical expression which is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable to an output variable.

Based on the table shown above, we can reasonably infer and logically deduce that it does not represent a function because the input values (domain or independent values) are not uniquely mapped to the output values (range or dependent values).

Answer:

Podemos usar una regla de tres para resolver este problema.

Si 4 máquinas llenan 12 000 botellas en 2,5 horas, entonces en una hora pueden llenar:

12 000 botellas / 2,5 horas / 4 máquinas = 1 200 botellas por hora por máquina

Para llenar 25 200 botellas en 3,5 horas, se necesitaría llenar:

25 200 botellas / 3,5 horas = 7 200 botellas por hora

Para llenar 7 200 botellas por hora, se necesitarían:

7 200 botellas por hora / 1 200 botellas por hora por máquina = 6 máquinas

Por lo tanto, se necesitarían 6 máquinas embotelladoras para llenar el pedido en 3,5 horas.

Step-by-step explanation:

The solution is: a) 1,2,6,24,120 are the first five terms of the sequence in which the nth term is a_n=(n+1)!/n+1.

Here, we have,

The formula for the nth term of the sequence is expressed as

n=(n+1)!/n+1

For the first term, n = 1.

Therefore,

(1+1)!/(1+1)

= 2!/2

= (2×1)/2

= 1

For the second tern, n = 2.

Therefore,

(2+1)!/2+1

= 3! /3

= (3×2×1)/3

= 6/3

= 2

For the third term, n = 3,

therefore

(3+1)!/3+1

= 4!/4

=(4×3×2×1)/4

= 6

For the fourth term, n = 4.

Therefore

(4+1)!/4+1

= 5!/5

= (5×4×3×2×1)/5

= 24

For the fifth term, n = 5.

Therefore

(5+1)!/5+1

= 6!/6

= 6× 5×4×3×2×1)/6

= 120

Hence, The solution is: a) 1,2,6,24,120 are the first five terms of the sequence in which the nth term is a_n=(n+1)!/n+1.

Step-by-step explanation:

To calculate the amount Fred paid for Social Security and Medicare taxes in 2020, we first need to calculate the amount of income subject to Social Security tax.

Since Fred earned $125,000, which is less than $157,700, all of his income is subject to Social Security tax.

Therefore, the amount of Social Security tax Fred paid in 2020 is:

$125,000 x 8.25% = $10,312.50

To calculate the amount of Medicare tax Fred paid in 2020, we simply multiply his income by the Medicare tax rate:

$125,000 x 1.5% = $1,875

Therefore, Fred paid a total of $10,312.50 + $1,875 = $12,187.50 for Social Security and Medicare taxes in 2020.

Step-by-step explanation:

The combined area of the mirror and the frame is equal to  π(r+2)² square inches.

Width of circular frame surrounds the mirror = 2 inches

Let us denote the radius of the circular mirror by r.

Then, the radius of the circular frame that surrounds the mirror is 'r + 2'.

The combined area of the mirror and the frame is the sum of the areas of the mirror and the frame.

The area of the mirror is πr²,

And the area of the frame

= Area of the larger circle with radius r+2  - Area of the smaller circle with radius r

⇒ Area of frame = π(r+2)² - πr²

Simplifying this expression, we get,

⇒ Area of frame = π(r² + 4r + 4) - πr²

⇒ Area of frame = πr² + 4πr + 4π - πr²

⇒ Area of frame = 4πr + 4π

The combined area of the mirror and the frame is,

πr² + 4πr + 4π

There is no specific value for r.

So we cannot calculate the exact area.

Simplify the expression by factoring out π,

=πr² + 4πr + 4π

= π(r² + 4r + 4)

= π(r+2)² square inches.

Therefore, the combined area of the mirror and the frame is π times the square of the sum of the radii of the mirror and the frame, which is (r+2)².

The total length of fencing needed for the yard is 46√2 meters.

To find the total length of fencing needed for the yard, we need to add up the length of all four sides of the fence.

The long side of the yard is 12√2 meters, but we need to add the √2-meter section that runs up to the house to get the total length of the fence for that side:

12√2 + √2 = 13√2

The two shorter sides are each 5√2 meters, so the total length of the fence for both of these sides is:

2(5√2) = 10√2

To find the total length of fencing needed, we add up the lengths of all four sides:

f = 13√2 + 10√2 + 13√2 + 10√2

Simplifying the expression, we can combine like terms:

f = (13 + 10 + 13 + 10)√2

The discount on the game console is 15.89% of the selling price.

To find the discount as a percentage of the selling price, we first need to calculate the discount amount. This can be found by subtracting the selling price from the original price:

Discount = Original Price - Selling Price

Discount = $428 - $360

Discount = $68

Next, we can calculate the discount as a percentage of the selling price by dividing the discount amount by the selling price and multiplying by 100:

Discount % = (Discount / Selling Price) * 100

Discount % = ($68 / $428) * 100

Discount % = 0.1589 * 100

Discount % = 15.89%

Therefore, the discount on the game console is 15.89% of the selling price.

After comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

A transformation known as a rotation involves turning the figure either clockwise or counterclockwise. The centre of rotation is the fixed location where the rotation occurs. The term "angle of rotation" refers to the amount of rotation. A figure can be rotated 90 degrees, or a quarter turn, in either a clockwise or counterclockwise direction.

You have rotated the figure 180 degrees when you have spun it exactly halfway. The figurine may be rotated 360° by turning it all the way around. A counterclockwise turn has a positive magnitude because a clockwise rotation indicates a negative magnitude. Rotational symmetry exists in every regular polygon. When an object is rotated around its centre, it retains its original appearance. The object is then referred regarded as having rotational symmetry.

Let's write the coordinates of the original figure,

A = (1, -5)

B = (6, -2)

C = (6, -5)

D = (1, -8)

Now, if we rotate it 90 degrees counterclockwise, the coordinates are:

A' = ( 5, 1)

B' = (2, 6)

C' = (5, 6)

D' = (8, 1)

Now if we rotate it again 90 degrees counterclockwise, the coordinates are:

A'' = ( -1, 5)

B'' = (-6, 2)

C'' = (-6, 5)

D'' = (-1, 8)

Now from the figure, let's write the coordinates.

A' = ( -1, 5)

B' =  (-6, 2)

C' = (-6, 5)

D' =  (-1, 8)

This is the same as the coordinates of the second 90 degrees counterclockwise rotation.

Since we did two 90 degrees rotations, we can say we did a total of 180° counterclockwise rotation.

Therefore after comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

Answer:

12cm aka B.

Step-by-step explanation:

In a 30-60-90 triangle, the hypotenuse is always twice as long as the shorter leg, and the longer leg is √3 times as long as the shorter leg.

Since the length of the shorter leg is 6 cm, the hypotenuse is:

2 times the length of the shorter leg = 2 × 6 cm = 12 cm

Therefore, the length of the hypotenuse of the triangle is 12 cm.

Answer:

Total cost = Total volume x Cost per cubic meter = 0.6144 cubic meters x S$10/cubic meter = S$6.14

Therefore, the total cost of the pile of paper is S$6.14.

Step-by-step explanation:

Length = 40 cm = 0.4 m

Width = 32 cm = 0.32 m

Thickness = 0.8 mm = 0.0008 m

The total cost of a pile of paper with a height of 4.8 meters is she.0.0049152.

Length of paper: 40 cm = 0.4 m

Width of paper: 32 cm = 0.32 m

Thickness of paper: 0.8 mm = 0.0008 m

Volume of a single sheet of paper = Length × Width × Thickness

= 0.4 m × 0.32 m × 0.0008 m

= 0.0001024 m³

Total volume of the pile = Volume of a single sheet of paper × Height of the pile

= 0.0001024 m³ × 4.8 m

= 0.00049152 m³

Total cost = Total volume of the pile × Cost per cubic meter

= 0.00049152 m³ × she.10/m³

To prove this identity, we start with Fermat's Little Theorem, which states that if p is a prime number and a is any integer coprime to p, then a^(p-1) ≡ 1 (mod p).

Using this theorem, we can rewrite the given identity as a^(p-1) * a(p-2) ≡ 1 (mod p^2).

Next, we can multiply both sides by a to get a^(p-1) * a(p-1) ≡ a (mod p^2).

Since a and p are coprime, we can use Euler's Totient Theorem, which states that a^φ(p) ≡ 1 (mod p) where φ(p) is the Euler totient function. Since p is prime, φ(p) = p-1, so a^(p-1) ≡ 1 (mod p).

Using this result, we can rewrite our identity as a^(p-1) * a(p-1) * a^-1 ≡ a^(p-1) ≡ 1 (mod p), which implies that a^(p-1) ≡ 1 (mod p^2).
