Step-by-step explanation: Let's look at one pair at a time. In order to go from 5 to 19 you would need to multiply 5 by 3.8, and to go from 4 to 12 you would need to multiply 4 by 3

The perimeter and the area of each composite figure is summarized below:

Case 1: p = 2 · (4√2 + 5), A = 20

Case 2: p = 28, A = 16

Case 3: p = 4 · (√13 + 2), A = 48

In this problem we find three cases of composite figures, whose perimeters and areas should be found. The perimeter is the sum of all side lengths and the area is the sum of areas of simple figures. The area formulas needed are introduced below:

Triangle

A = 0.5 · b · h

Rectangle

A = b · h

Where:

The length of oblique lines are determined by Pythagorean theorem, whereas lengths of horizontal and vertical lines are found by direct inspection. Now we proceed to find the perimeter and area of each figure:

Case 1:

p = 4 · √(2² + 2²) + 2 · 5

p = 4√8 + 10

p = 8√2 + 10

p = 2 · (4√2 + 5)

A = 4 · 5

A = 20

Case 2:

p = 2 · 6 + 4 · 1 + 4 · 2 + 2 · 2

p = 12 + 4 + 8 + 4

p = 28

A = 2 · 6 · 1 + 2²

A = 12 + 4

A = 16

Case 3:

p = 4 · √(2² + 3²) + 2 · 4

p = 4√13 + 8

p = 4 · (√13 + 2)

A = 4 · 6 + 4 · 0.5 · 2 · 3

A = 24 + 24

A = 48

1. Domain: all real values

2. Zeros: 0 (with multiplicity 2) and 3

3. Not periodic. Symmetric about the point (1, 2)

4. Positive for x < 3; negative for x > 3

5. f → ∞ as x → -∞; f → -∞ as x → ∞

6. none

EXPLANATION

1. The domain of a function is the set of all the x-values for which the function exists. In this case, we have a polynomial function and, therefore, the domain is all real values.

2. To find the zeros of the function, we have to solve,

First, factor x² and -1 out. To do so, we have to divide each term by x² and by -1 - or, in other words, divide by -x²,

So, we have,

In this equation, we can see that if x = 0, then the equation is true. Also, if x = 3 the equation is true. So, these are the two zeros, with the particularity that x = 0 has multiplicity 2. This is because the factor related to that zero is x squared.

Hence, the zeros are 0 and 3. 0 has multiplicity 2.

3. As mentioned before, this is a polynomial function, which means that it is not a periodic function. A cubic function is an odd function, and it is symmetric about the origin. However, this function is not the parent function, x³, but it is symmetric about the point (1, 2).

4. We know that the function is zero at x = 0 and at x = 3. For x < 0, the function is positive,

For 0 < x < 3, the function is also positive. This is because x = 0 with multiplicity 2.

Then, since the function crosses the x-axis at x = 3 and that zero has multiplicity 1, we can conclude that the function is negative for x > 3.

Hence, is the function is positive for x < 3 and negative for x > 3.

5. As mentioned in part 4, the function is positive for all values of x less than 3, which means that the function goes to infinity as x goes to negative infinity.

Since for x > 3 the function is always negative, it goes to negative infinity as x goes to infinity.

6. A polynomial function has no restrictions in the domain and, therefore, has no asymptotes.

Graph is a type of data structure that consists of a set of nodes (also called vertices) and edges. Each node is connected to other nodes by edges. Graphs are used to represent networks of communication, data organization, computational devices, the flow of computation, etc. They are also very useful for visualizing relationships between data points in a variety of fields.

The translation of the parent graph of f(x)=√x+3+2 is a vertical shift upward 3 units, followed by a horizontal shift to the right 2 units. This is represented by the bold line in the graph. In terms of the equation, the translation is represented by the addition of the 3 and the 2 to the function. The 3 causes the graph to shift vertically upward and the 2 causes the graph to shift horizontally to the right. As a result, the graph of f(x)=√x+3+2 is shifted 3 units up and 2 units to the right from the parent graph of f(x)=√x.

D. Each segment of the electorate provides significant support to Mr Quintana

Step-by-step explanation:

From the question, we have the following logic statement;

If those segment that provide significant support to Ms Puerto also provide support to Mr. Quintana then no segment of the electorate that provides significant support to Mr. Quintana provides significant support to Mr. Ramirez

Counter to the If Then Logic structure

At least one segment of the lectorate provides significant support to Mr. Quintana and Mr. Ramirez

Therefore, there is at least one segment that provides support to Mr. Quintana but not to Ms. Puerta

The segments that provide support to Ms. Puerta do not provide support to Mr. Ramirez

Mr. Quintana's support includes those from the supporters of Ms. Puerta and those from the supporters of Mr. Ramirez

Therefore, each segment of the electorate provide significant support to Mr. Quintana.

To determine if the inspector is justified in claiming that all the engine fan blades must be replaced, we can perform a hypothesis test using the sample variance and the given population variance threshold.

The null hypothesis (H0) is that the population variance is less than or equal to 0.18 mm2, and the alternative hypothesis (Ha) is that the population variance is greater than 0.18 mm2.

Using the chi-square distribution and a significance level of 0.01, we can calculate the critical chi-square value that corresponds to the upper tail area of 0.01.

Next, we calculate the chi-square test statistic using the sample variance, the sample size, and the population variance threshold. If the test statistic exceeds the critical chi-square value, we reject the null hypothesis and conclude that the fan blades must be replaced.

To find a 90% confidence interval for the population standard deviation, we can use the chi-square distribution and the degrees of freedom (n-1), where n is the sample size. The confidence interval will be constructed based on the chi-square values corresponding to the lower and upper tails of 0.05 each.

Performing these calculations will provide the necessary information to determine if the inspector is justified in claiming that all the engine fan blades must be replaced and to establish the confidence interval for the population standard deviation.

It will take approximately 20 years for the population of San Diego to double at a growth rate of 3.5% per year

To find out how long it will take for the population to double, we can use the rule of 70. The rule of 70 states that to find the approximate number of years it takes for a quantity to double, divide 70 by the annual growth rate as a percentage.

In this case, the annual growth rate is 3.5%, so we can calculate the doubling time as follows:

70 / 3.5 = 20

Answer:

percentage error = 39.1%

Step-by-step explanation:

You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.

Given that You estimate that there are 64 marbles in a jar.

The actual amount is 46 marbles

Actual marbles = 46

Your estimate = 64

\(\% error =\frac{estimated - actual}{actual}\)

% error = | estimate - actual | / actual × 100%

estimate amount - actual amount = 64 - 46 = 18

\(= \frac{18}{46} \times 100\\\\=0.391\times 100\\\\=39.1 \%\)

Therefore,  percentage error = 39.1%

The given table represents the counts from three independent random samples taken from three major cities regarding whether teenagers consumed a soft drink in the past week.

By summing up the counts of teenagers who consumed a soft drink from all three cities and dividing it by the total number of teenagers surveyed, we can calculate the overall proportion. Dividing this proportion by the total number of teenagers and multiplying by 100 will give us the percentage of teenagers who consumed a soft drink.

For example, if the first city had a count of 150 teenagers who consumed a soft drink out of a total of 300 surveyed, the second city had 200 out of 400, and the third city had 180 out of 350, the overall proportion would be (150 + 200 + 180) / (300 + 400 + 350) = 530 / 1050. Multiplying this by 100, we find that approximately 50.48% of teenagers consumed a soft drink in the past week based on the combined sample.

90

By solving the equation 510 = 2(6x + 11x), we know that the length of the given rectangle is 90 units.

It primarily consists of a variable, sometimes with a numerical constant in addition.

Take the following illustration into consideration to quickly grasp this idea. 3x – 4 = 5. It is a simple equation of class 7.

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

So, we know that the ration is 6:11 and the perimeter is 510 units.

Then, form and solve the equation as follows:

510 = 2(6x + 11x)

510 = 12x + 22x

510 = 34x

x = 510/34

x = 15

Then, the length will be:
6x

6(15)

90 units

Therefore, by solving the equation 510 = 2(6x + 11x), we know that the length of the given rectangle is 90 units.

a) The equations of the streamlines are: r = c sin(θ)/constant; r = -c cos(θ)/constant. b) For the vortex flow, the time rate of change of the volume of a fluid element per unit volume is zero. c) For the vortex flow, the vorticity is (2 c/r2)e_r.

a) The equations of the streamlines can be obtained by setting the velocity field equal to a constant. This means that u = cy/(x2+y2) = constant and v =-cx/(x2+y2) = constant. To simplify these equations, we can use polar coordinates where x = r cos(θ) and y = r sin(θ). Substituting these into the equations for u and v gives us:
u = c sin(θ)/r = constant
v = -c cos(θ)/r = constant
Solving these equations for r gives us the equations of the streamlines:
r = c sin(θ)/constant
r = -c cos(θ)/constant

b) The time rate of change of the volume of a fluid element per unit volume can be calculated using the divergence of the velocity field. The divergence of the velocity field in polar coordinates is given by:
∇ ⋅ u = (1/r)(∂(r u_r)/∂r + ∂(r u_θ)/∂θ)
Substituting the expressions for u_r and u_θ in terms of u and v gives us:
∇ ⋅ u = (1/r)(∂(r (u cos(θ) + v sin(θ)))/∂r + ∂(r (-u sin(θ) + v cos(θ)))/∂θ)
Substituting the expressions for u and v in terms of c, r, and θ gives us:
∇ ⋅ u = (1/r)(∂(r (c sin(θ)/r cos(θ) - c cos(θ)/r sin(θ)))/∂r + ∂(r (-c sin(θ)/r sin(θ) - c cos(θ)/r cos(θ)))/∂θ)
Simplifying this expression gives us:
∇ ⋅ u = 0
This means that the time rate of change of the volume of a fluid element per unit volume is zero for the vortex flow.

c) The vorticity of the vortex flow can be calculated using the curl of the velocity field. The curl of the velocity field in polar coordinates is given by:
∇ × u = (1/r)(∂(r u_θ)/∂r - ∂u_r/∂θ)e_r + (∂u_r/∂θ - ∂u_θ/∂r)e_θ
Substituting the expressions for u_r and u_θ in terms of u and v gives us:
∇ × u = (1/r)(∂(r (-u sin(θ) + v cos(θ)))/∂r - ∂(u cos(θ) + v sin(θ))/∂θ)e_r + (∂(u cos(θ) + v sin(θ))/∂θ - ∂(-u sin(θ) + v cos(θ))/∂r)e_θ
Substituting the expressions for u and v in terms of c, r, and θ gives us:
∇ × u = (1/r)(∂(r (-c sin(θ)/r sin(θ) - c cos(θ)/r cos(θ)))/∂r - ∂(c sin(θ)/r cos(θ) - c cos(θ)/r sin(θ))/∂θ)e_r + (∂(c sin(θ)/r cos(θ) - c cos(θ)/r sin(θ))/∂θ - ∂(-c sin(θ)/r sin(θ) - c cos(θ)/r cos(θ))/∂r)e_θ
Simplifying this expression gives us:
∇ × u = (2 c/r2)e_r
This means that the vorticity of the vortex flow is (2 c/r2)e_r.

we are asked to determine the surface area of a cube that has a side length of 12 cm.

To do that let's remember that a cube has 6 faces and the area of each face is its side length squared. Therefore, the total surface area is the side length squared multiplied by 6:

Solving the operation:

181 sq cm

Step-by-step explanation:

Answer:Total surface area of cubes (TSA) = 6a2

(1) a = 3cm

TSA = 6 × 3 × 3, TSA = 54 sq.cm

(2) a = 5 cm TSA = 6 × 5 × 5, TSA = 150 sq.cm

(3) a = 5,5 cm, TSA = 6 × 5.5 × 5.5

TSA = 181.5 sq. cm

A) Se requiere 10 árboles por hilera.

B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Step-by-step explanation:

A) A continuación, realizamos la descomposición factorial de cada número:

Naranjos

\(720 = 2 \times 2 \times 2 \times 2 \times 3\times 3\times 5\)

\(720 = 2^{4}\times 3^{2}\times 5\)

Mandarinos

\(250 = 2\times 5\times 5\times 5\)

\(250 = 2\times 5^{3}\)

Mamoneros

\(360 = 2\times 2\times 2\times 3\times 3\times 5\)

\(360 = 2^{3}\times 3^{2}\times 5\)

Nísperos

\(480 = 2\times 2\times 2\times 2 \times 2\times 3\times 5\)

\(480 = 2^{5}\times 3\times 5\)

El máximo común divisor de los cuatro números representa el número de árboles de cada hilera considerando el menor número posible de hileras, cuyo valor es \(2\times 5 = 10\). Se requiere 10 árboles por hilera.

B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por el resultado del punto anterior:

Naranjos

\(x = \frac{720}{10}\)

\(x= 72\)

Mandarinos

\(x = \frac{250}{10}\)

\(x = 25\)

Mamoneros

\(x = \frac{360}{10}\)

\(x = 36\)

Nísperos

\(x = \frac{480}{10 }\)

\(x = 48\)

El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Teniendo en cuenta la definición de m.c.m:

A) Se requieren 10 árboles por hilera.

B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

A) Para hallar la cantidad de árboles que posee cada hilera debes hallas el m.c.d entre 720, 250, 360 y 480.

El máximo común divisor, m.c.d., de dos o más números es el mayor número que divide a todos de manera exacta, es decir, es el mayor de los divisores que tienen en común dos o más números.

El mínimo común múltiplo se suele expresar con las siglas m.c.d. (a, b), siendo a y b los números.

Para calcular el mínimo común múltiplo de dos o más números, de debe descomponer los números en factores primos (son los números que sólo son divisibles por sí mismos o por el número 1). En este caso:

720= 2×2×2×2×3×3×5= 2⁴×3²×5

250=2×5×5×5= 2×5³

360=2×2×2×3×3×5= 2³×3²×5

480=2×2×2×2×2×3×5= 2⁵×3×5

El mínimo común múltiplo se obtiene escogiendo todos los factores comunes, elevados a la menor potencia. Es decir, se escoge aquellos factores que aparecen en todas las descomposiciones la menor cantidad de veces. En este caso:

mcd (720,250,360, 480)= 2×5= 10

Entonces, se requiere 10 árboles por hilera.

B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por la cantidad de árboles que se requiere por hilera:

Naranjos: 720÷10= 72

Matas de mandarina: 250÷10= 25

Mamon: 360÷10= 36

Níspero: 480÷10= 48

El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

By using the travel distance formula, we found out that it takes 1 hour for the car and the truck to meet if they leave at the same time and travel toward each other.

It is given to us that -

Two cities are 145 miles apart

Truck travels this distance in 2.5 hours

Car is 1.5 times as fast as the truck

We have to find out the time taken for the car and the truck to meet if they leave at the same time, and travel toward each other.

We know that -

\(Speed = \frac{Distance}{Time}\) ----- (1)

Let us say that the speed of the truck is given by \(S_{t}\) and the speed of the car is given by \(S_{c}\).

Now, from equation (1), we can say that the speed of the truck,

\(S_{t}=\frac{145}{2.5} \\= > S_{t}= 58 miles per hour\) ----- (2)

It is given to us that the car is 1.5 times as fast as the truck

=> \(S_{c}= 1.5 * 58\\= > S_{c}= 87 miles per hour\) ----- (3)

It is mentioned that the car and the truck leave at the same time to meet each other.

Let us say that the truck meets the car at a distance 'd'.

This implies that the distance travelled by the car to meet the truck at a given point = (145-d)  --- (4)

From equation (1), we can say that

\(Time = \frac{Distance}{Speed}\)

Also, we know that -

Time taken by truck to travel d miles = Time taken by car to travel (145-d) miles

\(\frac{d}{58}=\frac{145-d}{87} \\= > 87d = 8410-58d\\= > 145d=8410\\= > d = 58\)

Thus, the truck will travel 58 miles to meet car after they leave at the same time.

So, the time taken for the car and truck to meet =

\(\frac{58 miles}{58 miles per hour} = 1 hour\)

Therefore, according to the distance formula, it takes 1 hour for the car and the truck to meet if they leave at the same time and travel toward each other.
