Answer/Step-by-step explanation:

As the input increases by 1, the output decreases by 4. The missing number for the Input is 6, and the missing number for output is -17.

Por lo tanto, la parcela mide 18 metros de largo y 12 metros de ancho.

Llamemos "largo" (L) a una de las dimensiones de la parcela y "ancho" (A) a la otra dimensión.

Según la información dada, sabemos que la suma del largo y el ancho es de 30 metros:

L + A = 30 ---(1)

También se nos dice que la diferencia entre el largo y el ancho es de 6 metros:

L - A = 6 ---(2)

Podemos resolver este sistema de ecuaciones utilizando el método de sustitución o de eliminación. En este caso, resolveremos utilizando el método de sustitución.

De la ecuación (2), podemos despejar L en términos de A:

L = A + 6

Sustituyendo este valor de L en la ecuación (1), obtenemos:

(A + 6) + A = 30

2A + 6 = 30

Restamos 6 de ambos lados de la ecuación:

2A = 30 - 6

2A = 24

Dividimos ambos lados de la ecuación por 2:

A = 12

Ahora que conocemos el valor de A, podemos encontrar el valor de L sustituyendo en la ecuación (2):

L = A + 6

L = 12 + 6

L = 18

Answer:

\(4(x^4+7)\)

Step-by-step explanation:

Taking out the greatest common factor,\(16x^4+28=4(x^4+7)\).

3. The volume of the Pringle Chips container is approximately 2034.72 cubic inches.

4. The cake takes up approximately 7317 cubic inches of space.

5. The volume of foam in the model of the volcano is approximately 7234.08 cubic centimeters.

1. The units for Volume are always cubed.

2. Volume is the amount of space an object takes up. True.

3. To calculate the volume of the Pringle Chips container, we need to find the volume of a cylinder. The formula for the volume of a cylinder is V = πr^2h, where π is a constant (approximately 3.14), r is the radius, and h is the height. Given that the diameter is 9 inches, the radius would be half of that, which is 4.5 inches. Substituting the values into the formula, we have:

V = 3.14 * (4.5)^2 * 32

V = 3.14 * 20.25 * 32

V ≈ 2034.72 cubic inches

4. To find the volume of the 3-tier cake, we need to find the volume of each tier separately and then add them together. Since all the tiers are cylinders, we can use the formula V = πr^2h.

Tier 1:

V1 = 3.14 * (12)^2 * 10 = 4521.6 cubic inches

Tier 2:

V2 = 3.14 * (8)^2 * 10 = 2010.4 cubic inches

Tier 3:

V3 = 3.14 * (5)^2 * 10 = 785 cubic inches

Total volume:

Total V = V1 + V2 + V3

Total V = 4521.6 + 2010.4 + 785

Total V ≈ 7317 cubic inches

5. To find the volume of the Styrofoam model of the volcano, we can use the formula for the volume of a cone, V = (1/3)πr^2h. Given that the diameter is 48 centimeters, the radius would be half of that, which is 24 centimeters. Substituting the values into the formula, we have:

V = (1/3) * 3.14 * (24)^2 * 12

V = (1/3) * 3.14 * 576 * 12

V ≈ 7234.08 cubic centimeters

the left side of this equation equal the right side through the process of completing the square that establishes the equality between the left side and the right side of the Gaussian integral equation.

using  completing the square method:

Starting with the left side of the equation:

∫\(e^(^-^x^2)\) dx

\(e^(^-^x^2) = (e^(^-x^2/2))^2\)

∫\((e^(^-^x^2/2))^2 dx\)

let  u = √(x²/2) =  x = √(2u²).

dx = √2u du.

∫ \((e^(^x^2/2))^2 dx\)

= ∫ \((e^(^-2u^2)\)) (√2u du)

The integral of \(e^(-2u^2)\)= √(π/2).

∫ \((e^(-x^2/2))^2\) dx

= ∫  (√2u du) \((e^(-2u^2))\\\)

= √(π/2) ∫ (√2u du)

We substitute back  u = √(x²/2), we obtain:

Answer:

The lest distance in feet that could have been traveled is 480 + 480·√3 feet or approximately 1311.38 feet

Step-by-step explanation:

The parameters given are;

Six boys equally spaced round a circle

Radius of circle = 40 feet

Angle subtended by the arc between 2 boys = 360°/6 = 60°

Path of motion of each boy = To the other non adjacent boys = Inscribed Kite

∴ Path of motion of each boy = Right kite

Interior angles of the right kite = 90°, 90°, 120°, 60° (Angles subtended at the center = 2 × angle at the circumference)

Hence distance traveled by each boy = Perimeter of the right kite

Therefore, the distance traveled by each boy = 2 × (Long diagonal × sin((largest angle)/2) + Long diagonal × cos((largest angle)/2)

The distance traveled by each boy = 2 × (80 × sin(60) + 80 × cos(60))

\(The\, distance\, traveled\, by \, each\, boy = 2\times \left (80\cdot \dfrac{\sqrt{3}}{2}+80\times \dfrac{1}{2} \right )\)

\(The\, distance\, traveled\, by \, each\, boy = 80 + 80\cdot \sqrt{3}}\)

Hence we have;

The distance traveled by the six boys = 6 × (80 + 80·√3) = 480 + 480·√3 feet.

The lest distance in feet that could have been traveled = 480 + 480·√3 feet = 1311.38 feet.

factors-----(a+2)(a^2+4-3a)

The equation of a circle is written as (x – h)^2 + (y – k)^2 = r^2

h and k are the center point and r is the radius.

In the given equation h = -6 and k = 7 and r would be the square root of 81, which is 9.

Center (-6,7)

Radius = 9

The required center is \((-6,7)\) and the radius is 9 units.

Given equation is,

\((x + 6)^2 + (y-7)^2 = 81\)....(1)

Equation of the circle: The general equation of the circle with the center (a,b) and the radius r is represented by,

Answer:

dad paid 37.19

Step-by-step explanation:

The z-score of -1.6 is less than 2.00 but greater than -2.00.

Hence, we can conclude that the value is not unusual.

The correct answer is: -1.6; not unusual.

When we are given a test score of 48.4 on a test that has a mean of 66 and a standard deviation of 11,

we need to find the corresponding z-score and determine whether the value is unusual or not.

The formula for calculating z-score is:

z = (x - μ) / σ

Where, z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.

Substituting the given values in the formula, we get: z = (48.4 - 66) / 11z = -1.6

Therefore, the z-score corresponding to the given value is -1.6.

Now, we need to determine whether this value is unusual or not.

A score is considered unusual if its z-score is less than -2.00 or greater than 2.00.

C. 2.00

D. 11.09

Answer:

Under the assumption of independence, the expected frequency in the upper left cell is 12.47

Option A) 12.47 is the correct Option

Step-by-step explanation:

Given the data in table in the question;

the expected frequency in the upper left cell will be;

Eij = (Ti × Tj) / N

Row total Ti = 38

Column total Tj = 42  

Total frequency N = 128

so we substitute

Eij = (38 × 42) / 128

= 1596 / 128

= 12.468 ≈ 12.47

Therefore Under the assumption of independence, the expected frequency in the upper left cell is 12.47

Answer:

The square root is 1.90

Step-by-step explanation:

Given

\(x = \sqrt{3.6}\)

Required

Find x

Express 3.6 as 36/10

So, we have:

\(x = \frac{\sqrt{36}}{\sqrt{10}}\)

This gives

\(x = \frac{6}{\sqrt{10}}\)

Rationalize

\(x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}\)

\(x = \frac{6\sqrt{10}}{10}\)

Using a calculator

\(\sqrt{10} \approx 3.16\)

So, we have:

\(x = \frac{6*3.16}{10}\)

\(x = \frac{18.96}{10}\)

\(x = 1.896\)

Approximate

\(x = 1.90\)
