Answer:

A) Leo comió más, ya que comió 1/2 de la pizza.

B) Joel y Evelio comieron menos, ya que comieron 1/8 de la pizza.

C) Asimismo, Joel y Evelio comieron igual, ya que cada uno comió 1/8 de la pizza.

D) En total, entre todos comieron una pizza.

Step-by-step explanation:

Dado que cuatro amigos compraron una pizza, de la cual Leo se comió 1/2, Adán 1/4, Joel 1/8 y Evelio se comió lo que sobró, para determinar quién comió más, quién comió menos, quiénes comieron igual y cuántas pizzas se comieron en total se deben realizar los siguientes cálculos:

1/2 + 1/4 + 1/8 + X = 1

4/8 + 2/8 + 1/8 + X = 1

7/8 + X = 1

X = 1 - 7/8

X = 1/8

The approximation for y(1.4) using Euler's method with a step size of h = 0.05 is 14.402.

To approximate the value of y(1.4) using Euler's method with a step size of h = 0.05, we will take small steps from the initial condition y(1) = 9 to approximate the solution y(x) for values of x in the interval [1, 1.4].

The Euler's method formula is given by:

y(i+1) = y(i) + h * f(x(i), y(i))

where y(i) is the approximation of y at the ith step, x(i) is the corresponding x value, h is the step size, and f(x(i), y(i)) is the derivative of y with respect to x evaluated at x(i), y(i).

In this case, the given initial value problem is dxdy = x^2 + y and y(1) = 9.

Using Euler's method, we start with x(0) = 1 and y(0) = 9.

Step 1: x(1) = 1 + 0.05 = 1.05 y(1) = 9 + 0.05 * (1^2 + 9) = 9.5

Step 2: x(2) = 1.05 + 0.05 = 1.1 y(2) = 9.5 + 0.05 * (1.05^2 + 9.5) = 10.026

Repeating the above steps until we reach x = 1.4, we get the following results:

Step 3: x(3) = 1.1 + 0.05 = 1.15 y(3) = 10.026 + 0.05 * (1.1^2 + 10.026) = 10.603

Step 4: x(4) = 1.15 + 0.05 = 1.2 y(4) = 10.603 + 0.05 * (1.15^2 + 10.603) = 11.236

Step 5: x(5) = 1.2 + 0.05 = 1.25 y(5) = 11.236 + 0.05 * (1.2^2 + 11.236) = 11.93

Step 6: x(6) = 1.25 + 0.05 = 1.3 y(6) = 11.93 + 0.05 * (1.25^2 + 11.93) = 12.687

Step 7: x(7) = 1.3 + 0.05 = 1.35 y(7) = 12.687 + 0.05 * (1.3^2 + 12.687) = 13.51

Step 8: x(8) = 1.35 + 0.05 = 1.4 y(8) = 13.51 + 0.05 * (1.35^2 + 13.51) = 14.402

Therefore, the approximate value of y(1.4) using Euler's method with h = 0.05 is 14.402 .

Answer:

31,000 would be the answer for both. (I think).

Step-by-step explanation:

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²

Therefore, the area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Answer:

Step-by-step explanation:

1. For the sequence : 35, 29, 23, 17, ?; the next term is 11

2. For the sequence : 1, 2, 5, 10, ?; the next term is 17

From the question, we are to calculate the next term in each of the given sequence

From the given sequence,

35, 29, 23, 17, ?.

To determine the next term, we will determine the common difference

Common difference = Second term - First term

Common difference = 29 - 35

Common difference = -6

Thus,

To determine the next term, we will add the common difference to the last term

That is,

17 + - 6 = 17 - 6

= 11

The next term is 11

For the sequence 1, 2, 5, 10, ?.

Common difference = successive odd numbers

To get the second term, we will add to the first term the first natural odd number

To get the third term, we will add to the second term the second natural odd number

And so on.

In the given sequence, we are to determine the 5th term

Thus,

We will add to the fourth term, the fourth natural odd number

That is,

10 + 7 = 17

Hence, the next term is 17

Step-by-step explanation:

Let's represent the capacity of the small bucket as "x" and the capacity of the large bucket as "y".

From the first statement, we can set up the equation:

2x + y = 8

From the second statement, we can set up another equation:

y - x = 2

Now we can solve for "x" and "y".

Rearranging the second equation, we get:

y = x + 2

Substituting this value of "y" into the first equation, we get:

2x + (x + 2) = 8

Simplifying, we get:

3x + 2 = 8

Subtracting 2 from both sides, we get:

3x = 6

Dividing by 3, we get:

x = 2

Substituting this value of "x" into the second equation, we get:

y - 2 = 2

Simplifying, we get:

y = 4

Therefore, each small bucket can hold 2 cups of gasoline, and the large bucket can hold 4 cups of gasoline.

When x = 0 and y = 0, it is discovered that the inverse trigonometric function seen in the graph is represented by: B. Arcsin x = y

The trigonometric functions' inverses are known as inverse trigonometric functions in mathematics (with suitably restricted domains). They are used to determine an angle from any of the angle's trigonometric ratios and are specifically the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions. In engineering, navigation, physics, and geometry, inverse trigonometric functions are frequently employed. There are numerous notations for inverse trigonometric functions. Inverse trigonometric functions are typically named with an arc- prefix, such as arcsin(x), arccos(x), arctan(x), etc. Certain geometric relationships give birth to this notation: An arc with a length of r corresponds to an angle of radians when measured in radians, where r is the radius of the circle.

It basically represents what angle y has a trigonometric function value of x and has the notation y = f(x), where f is an inverse trigonometric function.

It is not necessary to use secant(1/cos) or tangent(sin/cos) in this case because the function(See Picture) has no vertical asymptotes.

Since f(0) = 0, it is y = Arcsin(x), as sin(0) = 0.

Answer: -5/14k-2

Step-by-step explanation:

We can get rid of the parenthesis because addition and subtraction are commutative. Therefore we get, -6/7k-7+5+1/2k

First combine the k's by forming a common denominator: -12/14k+7/14k=-5/14k

Now combine the constants: -7+5=-2

Next, combine the variables and constants: -5/14k-2

Therefore, our answer is -5/14k-2

We know that,

Probability of getting two non face cards = \(\frac{^{40}C_2}{{^{52}C_2}}\) = 10/17

Probability of not getting two non face cards = 1 - (10/17) = 7/17

Hence, we can write,

Money I will get = (7/17)*50*20 =  $ 411.764

Money I'll have to pay = (10/17)*30*20 = $ 352.94

We know that,

Money left with me = Money I will get - Money I'll have to pay

Educational inequality can be measured in different ways, including by looking at enrollment rates, completion rates, standardized test scores, and educational attainment levels.

Educational inequality refers to the unequal distribution of educational opportunities and resources among different groups of people within a society or country. This can manifest in various forms, including unequal access to education, disparities in educational outcomes, and differences in educational quality.

Educational inequality can be measured in different ways, including by looking at enrollment rates, completion rates, standardized test scores, and educational attainment levels. Other factors such as socio-economic status, race, ethnicity, and gender can also be used to analyze educational inequality.

Measuring the degree of educational inequality in a country is important for several reasons. First, it helps identify disparities in access to education and highlights groups that may be marginalized or disadvantaged. Second, it can provide insights into the effectiveness of educational policies and programs aimed at reducing inequality. Finally, reducing educational inequality is crucial for promoting social mobility, reducing poverty, and achieving economic growth and development.

In summary, educational inequality is a significant issue that can have far-reaching consequences for individuals and societies. Measuring and addressing educational inequality is important for promoting equity, social justice, and sustainable development.

(80/x)*x=(100/35)*x       - we multiply both sides of the equation by x

80=2.85714285714*x       - we divide both sides of the equation by (2.85714285714) to get x
