The area of ​​the land is equal to 40,000 m².

The number of ten thousand that can fit on the ground is 4.

The number of animals is equal to 400 animals.

Mathematically, the area of a trapezoid can be calculated by using this mathematical expression:

Area of trapezoid, A = ½ × (a + b) × h

Where:

By substituting the given parameters, we have the following:

Area of trapezoid, A = ½ × (a + b) × h

Area of trapezoid, A = ½ × (250 + 150) × 200

Area of trapezoid, A = (400) × 100

Area of trapezoid, A = 40,000 m².

For the number of ten thousand that can fit on the ground, we have:

Number of ten thousand = 40,000/10,000

Number of ten thousand = 4.

Finally, we would determine the number of animals as follows;

100 animals = 10,000 m²

x animals = 40,000 m²

By cross-multiplying, we have:

Therefore , the solution of the given problem of expression comes out to be the simplified expression is (x + 2) / (x - 5)(x - 1).

There is a requirement for mathematical operations as addition, multiplication, and division. When combined, they produce the following: A mathematical operator, some data, and an equation A statement of fact contains values, parameters, and mathematical operations including additions, subtractions, multiplications, and divisions. It is possible to contrast and compare various sentences and words.

Here,

First, let's factor all the quadratics in the expression:

x^2 + 4x + 4 = (x + 2)^2

x^2 - 4 = (x + 2)(x - 2)

x^2 - x - 6 = (x - 3)(x + 2)

x^2 - 5x + 6 = (x - 2)(x - 3)

Now, we can rewrite the expression as:

[(x + 2)^2 / (x + 2)(x - 2)] * [(x - 2)(x - 3) / (x - 3)(x + 2)] * [(x + 2)(x - 3) / (x - 2)(x - 3)] * [(x - 2)(x - 3) / (x - 5)(x - 1)]

Notice that the (x + 2)(x - 3) terms cancel out in the numerator and denominator of the second and third fractions, respectively. Also, (x - 2)(x - 3) cancels out in the numerator and denominator of the third and fourth fractions, respectively.

Simplifying these terms, we are left with:

= [(x + 2) / (x - 2)] * [(x - 2) / (x - 5)(x - 1)]

= (x + 2) / (x - 5)(x - 1)

Therefore, the simplified expression is (x + 2) / (x - 5)(x - 1).

Answer:

Part A:

Method B was solved incorrectly. The mistake that Sylvan made was in misinterpreting the problem. He used the number 12 as the value of one of the digits in the dividend, when it actually represents the number of bags of apples in the market.

Part B:

To solve the problem using Method B, we need to understand that the number 12 represents the number of bags of apples in one of the 64 bags. Therefore, we can find the total number of bags of apples by multiplying the number of bags by 12. This gives us:

64 x 12 = 768

Now, we can divide 768 by 10 to find the number of ten-pound bags of apples:

768 ÷ 10 = 76.8

Therefore, there are 76 ten-pound bags of apples in the market.

For Method A, Sylvan made no mistake, so there is no need to solve the problem again.

Answer:

The solutions to the equation f(x) = g(x) are approximately -4.59, -4.36, 2.11, and 2.84.

Step-by-step explanation:

To solve the eqation f(x) = g(x), we need to set the expressions for f(x) and g(x) equal to each other and solve for x. However, since g(x) involves an absolute value, we will need to consider two cases: one where 0.6x is positive, and one where it is negative.

Case 1: 0.6x is positive

In this case, we can write the equation as:

-0.25x³ - x² + 1.3x - 1.8 = 0.6x - 7.7

Simplifying, we get:

-0.25x³ - x² + 0.7x + 5.9 = 0

We can solve this equation using numerical methods, such as graphing or using a calculator, to find that x ≈ -4.59 and x ≈ 2.84.

Case 2: 0.6x is negative

In this case, we can write the equation as:

-0.25x³ - x² + 1.3x - 1.8 = -0.6x - 7.7

Simplifying, we get:

-0.25x³ - x² + 1.9x + 5.9 = 0

Again, we can use numerical methods to solve this equation and find that x ≈ -4.36 and x ≈ 2.11.

Therefore, the solutions to the equation f(x) = g(x) are approximately -4.59, -4.36, 2.11, and 2.84.

These roots are also complex conjugates, so the step response will be oscillatory with a decay factor. The response will look like a damped sinusoid. the value of s1 and s2 is 25i and -25j.

Here are the solutions for the given transfer functions and the corresponding step response plots:

G(s) =[tex]400 / (s^2 + 12s + 400)[/tex]

First, let's find the roots of the denominator:

[tex]s^2 + 12s + 400 = 0[/tex]

Using the quadratic formula, we get:

s1 = -6 + 14.96j

s2 = -6 - 14.96j

These roots are complex conjugates, so the step response will be oscillatory with a decay factor. The response will look like a damped sinusoid.

G(s) =[tex]900 / (s^2 + 90s + 900)[/tex]

The denominator can be factored as [tex](s + 45)^2[/tex]. Therefore, the roots are:

s1 = s2 = -45

Since both roots are negative and equal, the response will be critically damped.

G(s) = [tex]225 / (s^2 + 30s + 225)[/tex]

The denominator can be factored as[tex](s + 15)^2[/tex]. Therefore, the roots are:

s1 = s2 = -15

Again, since both roots are negative and equal, the response will be critically damped.

G(s) = [tex]625 / (s^2 + 625)[/tex]

The denominator can be factored as (s + 25j)(s - 25j). Therefore, the roots are:

s1 = 25j

s2 = -25j

Note: The step response plots can be sketched by considering the damping ratio and natural frequency of each transfer function. For critically damped systems, the response reaches steady-state the fastest, but it also overshoots the most.

The actual length of the living area is 134.4 feet if the length in the scale drawing is 16.8 in the scale.

To determine the actual length of the living space from a scale drawing, we need to use the scale factor, which is the ratio of the length in the drawing to the actual length. If the length in the scale drawing is 16.8 inches and the scale is given as a ratio of 1 inch in the drawing to 8 feet in actual size, we can set up a proportion:

1 inch (drawing) / 8 feet (actual)

= 16.8 inches (drawing) / x (actual)

We can cross-multiply and simplify to find x's value:

1 inch × x = 8 feet × 16.8 inches

x = (8 feet × 16.8 inches) / 1 inch

x = 134.4 feet.

Therefore, the actual length of the living space is 134.4 feet.

A combination of variables, constants, and mathematical operations like addition, subtraction, multiplication, and division make up an algebraic expression in mathematics. Mathematical, scientific, engineering, and engineering problems are represented and solved using algebraic expressions.

One or more variables, which represent unknowable or varying quantities, and one or more constants, which represent fixed values, can both be present in an algebraic expression. Typically, the variables are represented by letters like x, y, or z. The symbols +, -, x, and y, respectively, stand in for addition, subtraction, multiplication, and division. Additionally, terms are grouped and the order of operations are indicated by using parentheses.

For instance, the mathematical formula 3x + 2y - 5 combines the two variables x and y with the three constants 3, 2, and 5. While -5 is a constant term, the terms 3x and 2y are the variables multiplied by their coefficients.

By combining like terms, or terms with the same variable raised to the same power, algebraic expressions can be made simpler. For instance, the terms 3x and 4x, as well as 2y and -3y, are like terms in the expression 3x + 2y - 5 + 4x - 3y. These terms combined result in the abbreviated expression 7x - y - 5.

Mathematical operations like solving equations, graphing functions, and evaluating formulas all use algebraic expressions. Additionally, they are used in practical applications like figuring out interest rates, resolving optimization issues, and simulating natural phenomena.

The two longest ribbons cut from the spool are those with lengths of 63 and 69, according to the provided stem-and-leaf plot. Their total is therefore:

The value of the angle ∠EDC is 25 degrees for the triangle ABC.

According to the exterior angle theorem, an external angle's measure is equal to the sum of its remote interior angles' two opposite measures. Let's review a few fundamental facts concerning triangle angles: Three of a triangle's interior angles always add up to 180 degrees. This theorem is applied to all six of the exterior angles of the object. In order to make a linear pair of angles, an outer angle must be complementary to the neighbouring interior angle.

Given that, ∠B = ∠C and ∠BAD = 50 degrees.

Now, AE = AD hence, ∠ADE = ∠AED

Let ∠ADE = ∠AED = y.

From triangle ADC we have:

∠ADC = y + z

y + z = 50 + ∠B (exterior angles)

∠B = y + z - 50

Now, ∠B = ∠C thus,

∠C = y + z - 50

In triangle EDC we have:

∠E = x + y (exterior angles)

Also,

∠E + ∠D + ∠C = 180 (sum of interior angles of a triangle)

(x + y) + z + (y + z - 50) = 180

x + 2y + 2z = 230.........(1)

In triangle ADE,

x + 2y = 180

Substituting the values in 1 we have:

180 + 2z = 230

z = 25
