ΔABC ≅ ΔADC by Angle-Side-Angle (ASA) Congruence.

We have,

AC bisects ∠BAD

This means,

∠BAC = ∠DAC

And,

∠BCA = ∠DCA ( given)

Now,

- Angle-Side-Angle (ASA) Congruence.

The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.

ΔABC and ΔADC

∠BAC ≅ ∠DAC

Reason:

∠BAC = ∠DAC (AC bisects ∠BAD into half)

∠BCA = ∠DCA

Reason:

This is given in the figure

AC ≅ AC

Reason:

In two triangles, the two corresponding angles are equal so the remaining corresponding will be equal as well.

The side opposite to this angle is AC.

x + y < 3

Is the first one.

Here we have the following system of inequalities:

x + y > 4

x + y < 3

To identify the graph, we can write both of the inequalities as lines in slope-intercept form, then we will get:

y > -x + 4

y < -x + 3

So we will have two dashed lines, we need to shade the region above the first line and the region below the second line.

The first line passes through (0, 4) and the second through (0, 3), then the correct option is the first graph.

The equation of the line, after reflecting and translating it 5 units down, is y - 6 = 1200x - 1205.

To find an equation of a line parallel to the given equation in question 1, we can use the fact that parallel lines have the same slope.

The given equation is f(x) = –4(x – 50)(x – 250).

To determine the slope of this equation, we can rewrite it in slope-intercept form (y = mx + b), where m represents the slope.

Expanding and simplifying the given equation, we have:

[tex]f(x) = -4(x^2 - 300x + 12500)[/tex]

[tex]= -4x^2 + 1200x -50000[/tex]

The slope of this equation can be found by comparing it to the standard form y = mx + b:

m = 1200

Now, we can write the equation of a line parallel to the given equation. Since we don't have specific points, we can use the point-slope form of a linear equation: y - y1 = m(x - x1).

For example, let's choose the point (1, 1).

Plugging in the values into the equation, we have:

y - 1 = 1200(x - 1)

To simplify, we distribute the 1200:

y - 1 = 1200x - 1200

Next, we can translate the line 5 units down by subtracting 5 from both sides of the equation:

y - 1 - 5 = 1200x - 1200 - 5

y - 6 = 1200x - 1205

35 degrees

52 degrees

3(x + 2)

now, we know that,

sum of angle of triangle is 180 degrees

According to the angle sum property of a triangle, the sum of all three interior angles of a triangle is 180 degrees.

A triangle is a closed figure formed by three line segments, consisting of interior as well as exterior angles.

so, we get,

35 + 52 + 3(x + 2) = 180

The total materials handling cost allocated to the modular homes is $246,372.84.

The total materials handling cost allocated to the Prefab Barns is closest to $108,000.

To allocate materials handling cost based on material moves, we must determine proportion of material moves for each product and then apply that proportion to the total materials handling cost.

Proportion of material moves for Modular Homes:

= (Total expected material moves for Modular Homes) / (Total expected material moves for both products)

= 590 / (590 + 190)

= 0.756

Total materials handling cost allocated to Modular Homes:

= Proportion of material moves for Modular Homes * Total materials handling cost

= 0.756 * $325,890

= 246 372.84

= $246,372.84.

To allocate the materials handling cost based on direct labor-hours, we need to determine proportion of direct labor-hours for each product.

For Modular Homes:

Total direct labor-hours for Modular Homes:

= 6,000 units * 800 hours/unit

= 4,800,000 hours

For Prefab Barns:

Total direct labor-hours for Prefab Barns:

= 9,000 units * 300 hours/unit

= 2,700,000 hours

Total direct labor-hours for both products:

= 4,800,000 hours + 2,700,000 hours

= 7,500,000 hours

Proportion of direct labor-hours for Prefab Barns:

= 2,700,000 hours / 7,500,000 hours

= 0.36

Allocated materials handling cost for Prefab Barns:

= Proportion of direct labor-hours for Prefab Barns * Total materials handling cost

= 0.36 * $300,000

= $108,000.

The cost of one plate is $3.50 and the cost of one cup is $2.20.

Let's denote the cost of one plate as P and the cost of one cup as C. Based on the given information, we can set up a system of equations to solve for the cost of one plate and one cup.

From the first statement:

5P + 4C = 26.30   ...(1)

From the second statement:

6P + 5C = 32.00   ...(2)

To solve the system of equations, we can use the method of elimination or substitution. Let's use the elimination method here.

Multiplying equation (1) by 6 and equation (2) by 5 to make the coefficients of P equal, we have:

30P + 24C = 157.80   ...(3)

30P + 25C = 160.00   ...(4)

Subtracting equation (3) from equation (4), we get:

C = 2.20

Substituting the value of C into equation (1), we can solve for P:

5P + 4(2.20) = 26.30

5P + 8.80 = 26.30

5P = 17.50

P = 3.50

Therefore, the cost of one plate is $3.50 and the cost of one cup is $2.20.

The volume of the pyramid, to the nearest cubic foot, is approximately 5 ft^3. The correct option is A.

To find the volume of the solid oblique pyramid, we need to know the formula for the volume of a pyramid. The volume of a pyramid is given by the formula V = (1/3) * A * h, where A is the base area and h is the height of the pyramid.

In this case, the base is a regular pentagon with an edge length of 2.16 ft. The area of a regular pentagon can be calculated using the formula A = (1/4) * √(5 * (5 + 2√5)) * a^2, where a is the edge length. Substituting the given value, we find that the base area is 8 ft^2.

To find the height of the pyramid, we can construct a right triangle within the pyramid. The height of the pyramid corresponds to the height of this triangle.

The angle ACB is given as 30°, and since the triangle is right-angled, the angle opposite to the height is 90° - 30° = 60°. Therefore, we have a right triangle with one angle measuring 60°, and the opposite side is the height of the pyramid.

Now, we can use trigonometry to find the height. Since we know the length of the base and the angle opposite the height, we can use the tangent function. Tan(60°) = height / (2.16 / 2). Solving for height, we find that the height is approximately 1.98 ft.

Substituting the values into the formula for the volume, we have V = (1/3) * 8 * 1.98 ≈ 5.28 ft^3.

2. The absolute value of the complex number 12-9i is 15.

1. To plot the complex number 12-9i, we can visualize it on the complex plane. The real part (12) corresponds to the x-axis, and the imaginary part (-9) corresponds to the y-axis.

Plotting the complex number:

On the complex plane, we move 12 units to the right along the x-axis and 9 units downward along the y-axis to represent the complex number 12-9i.

Step-by-step explanation:

A quadratic function in factored form (x-a)(x-b) has zeros at (a, 0) and (b, 0). We are given the zeros in the graph are (-2, 0) and (4, 0). Thus, insert that into the factored form equation:

(x - (-2))(x - 4)

(x + 2)(x - 4)

Next, plug in a point from the function into the equation to find if a dilation was applied. Since we currently don’t know what the dilation is, let’s set it to variable d. I’ll be using the point (2, -8)

-8 = d(2 + 2)(2 - 4)

-8 = 4*-2d
