Answer: equal to the sum of the area of all of its faces

Step-by-step explanation:

Answer:The length of AC to one decimal place in the trapezium is 18.1 cm

Step-by-step explanation: Using Pythagoras theorem, we can find the length AC

Pythagoras theorem

c² = a² + b²

Therefore, draw a line from the point B to the line AD and call it line BX.

BX ║ CD

Therefore,

16² - 7² = BX²

256  - 49 = BX²

BX² = 207

BX = √207

BX = 14.3874945699

BX = 14.4 cm

Therefore,

11² + 14.4² = AC²

121 + 207.36 = AC²

AC = √328.36

AC = 18.120706388

AC = 18.1 cm

The sum of the measures of the exterior angles of the polygon is,  360°

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

Given that,

A polygon,

Having 9 equal sides,

The sum of the measures of the exterior angles of the polygon = ?

The sum of each interior & exterior angles are 180°

Suppose, interior angles  are respectively

a, b, c, d, e, f, g, h, i,

Now, exterior angles are respectively

180°-a, 180°-b, 180°-c, 180°-d, 180°-e, 180°-f, 180°-g, 180°-h, 180°-i,

The sum of the measures of the exterior angles of the polygon =

180°-a  + 180°-b +180°-c +180°-d + 180°-e + 180°-f  + 180°-g +180°-h + 180°-i,

1620 - (a + b + c + d + e + f + g + h + i)

Sum of all the interior angles  = (9-2)x180°

                                                  =  1260°

The sum of  the exterior angles of the polygon =  1620 - 1260°

                                                                               =   360°

Based on the manufacturing overhead applied to production during the period of $432,000, the fixed manufacturing overhead cost is $286,200.

The manufacturing overhead applied is determined as the product of the predetermined overhead rate and the actual machine hours consumed during the period.

Estimated machine hours to be worked = 55,000 hours

Actual machine hours during the period = 54,000 hours

Total manufacturing overhead applied to production = $432,000

Estimated variable manufacturing overhead per machine hour = $2.70

Total variable manufacturing overhead = $145,800 ($2.70 x 54,000)

Fixed manufacturing overhead (MOH) cost = $286,200 ($432,000 - $145,800)

Thus, the fixed manufacturing overhead cost is the difference ($286,200) between the total overhead cost applied and the variable manufacturing overhead cost.

The graph of the function y = f(x + 16) is a transformation of the original function f. This transformation has shifted the graph of f to the right by 16 units on the x-axis. This means that the value of x in the original function has been increased by 16, which has an effect on the corresponding value of y in the transformed function.

For example, if the point (a, b) is on the graph of f, then the point (a + 16, b) will be on the graph of y = f(x + 16). The x-coordinate of the point has been increased by 16, and since the transformation is a horizontal shift, the y-coordinate remains unchanged.

In summary, the graph of y = f(x + 16) is a reflection of the graph of f about the vertical axis. The transformation has the effect of shifting the graph to the right, but preserving the shape and overall form of the original function.

The general solution of the ODE is:

y(x) = e^-x * (1 - (e^x - 1) / 1) + (e^x - 1) / 1 * (e^x + 1) / 1, 0 ≤ x ≤ 1

y(x) = e^-x * (1 + (e^x - 1) / 1) - (e^x - 1) / 1 * (e^x + 1) / 1, x ≥ 1

This is a first-order linear ordinary differential equation (ODE) with constant coefficients. It can be solved using the method of integrating factors.

Let's multiply both sides by the integrating factor e^(∫p(x)dx), where p(x) = 1.

e^(∫p(x)dx) * Dy/dx + e^(∫p(x)dx) * y = e^(∫p(x)dx) * f(x)

D/dx (e^(∫p(x)dx) * y) = e^(∫p(x)dx) * f(x)

Integrating both sides, we get:

e^(∫p(x)dx) * y = ∫ e^(∫p(x)dx) * f(x) dx + C

where C is an arbitrary constant of integration.

Using the initial condition y(0) = 1, we can find the value of the constant C.

y(0) = 1 = e^(∫p(x)dx) * y(0) = e^(∫p(x)dx) * 1 = ∫ e^(∫p(x)dx) * f(x) dx + C

So, C = 1 - ∫ e^(∫p(x)dx) * f(x) dx

For 0 ≤ x ≤ 1, we have f(x) = 1 and:

∫ e^(∫p(x)dx) * f(x) dx = ∫ e^x dx = (e^x - 1) / 1

For x ≥ 1, we have f(x) = -1 and:

∫ e^(∫p(x)dx) * f(x) dx = ∫ -e^x dx = -(e^x - 1) / 1

Therefore, the general solution of the ODE is:

y(x) = e^-x * (1 - (e^x - 1) / 1) + (e^x - 1) / 1 * (e^x + 1) / 1, 0 ≤ x ≤ 1

y(x) = e^-x * (1 + (e^x - 1) / 1) - (e^x - 1) / 1 * (e^x + 1) / 1, x ≥ 1

In simpler terms, we have 33 minus half of 44 times x. The expression allows us to compute the value of the expression based on the input for the variable x, providing a way to evaluate the equation numerically.Let's dive deeper into the explanation.

The given expression is "33 - (2 * 22 * ½x)".

To simplify it, let's break it down step by step:

The term "2 * 22" is a multiplication operation that calculates the product of 2 and 22, resulting in 44.

Next, we have "½x". Here, ½ represents one-half, or 0.5. Multiplying 0.5 by x gives us 0.5x.

Putting it together, we have the term "44 * ½x". This means multiplying 44 by 0.5x, resulting in 22x.

Finally, we subtract the term "22x" from 33, giving us the expression "33 - 22x".

In summary, the expression represents the number 33 minus the product of 22 and the value of x, denoted as 22x. This expression allows us to calculate the result by substituting a specific value for x. It provides a way to compute the numerical outcome based on the given mathematical relationship.
