A quadrilateral with one set of parallel opposite sides is a trapezium. The bases and legs of a trapezium are referred to as parallel and non-parallel, respectively. It also goes by the name trapezoid.

As, The diagonals of a trapezium divide each other proportionally.

AO / OC = OB/ OD

Also, OA= OB and OC= OD

So, OA/ OC = 1: 1

In Triangle DOC and BOA

<AOB = <COD (Vertical Opposite angle)

<BAO = <OCD ( Alternate Interior angle)

By AA similarity Criteria  Triangle DOC and BOA are similar.

So, ar (Δ DOC)/ ar (ΔBOA)

= DO / OB = OC / OA = DC / BA

As, the ratio of corresponding length is equal.

So, the ratio of Triangle is 1:1

19 squares represent the area of the community that is desert

The area of the community that is houses is represented by 81 squares

Percentage is defined as the number that represents a ratio of a total that is divided by 100 equal parts. It is represented by the symbol %.

To solve this exercise, the percentage formula and the procedure to be applied is as follows:

As we can see in the picture the the desert has 10 square each side so the area will be:

A = 10*10

A = 100 squares

As the 19% of the area is only desert we have:

Desert = A*19%

Desert = 100*0.19

Desert = 19 squares

Now, the rest of area is the community that has houses, it is represented by:

A(houses) = A - desert

A(houses) = 100 squares - 19 squares

A(houses) = 81 squares

The percentage by which the number has to be decreased is 20%.

It represents a mathematical relationship or calculation. For example, the expression "2x + 3" is an algebraic expression that represents a linear equation with a variable x and constants 2 and 3. Algebraic expressions can be simplified, evaluated for specific values of the variables, and used to solve equations.

Given:

A number is increased by 25%

To find:

The percentage by which it has decreased

Solution:

The percentage by which the number has to be decreased is 20%.

We can find the percentage by following the given steps-

We know that a number increased by a percentage decreases by a different percentage.

Let us assume that the number is 100.

We know that this number has been increased by 25%.

So, the new number=100+25% of 100

=100+25/100×100

=100+25

=125

Now, the new number is 125.

Let us assume that this number has to be decreased by X% to obtain 100.

So, 125-X% of 125=100

125-X/100×125=100

125-1.25X=100

125-100=1.25X

25=1.25X

25×100/125=X

2500/125=X

X=20%

Therefore, the percentage by which the number has to be decreased is 20%.

If Bob wants to catch an elevator before the door closes. He is 42ft away when the door starts to close. How fast does he have to run in order to catch the elevator is: 12.50 ft/s.

Let's v represent Bob's speed in ft/s.

First, let's find the time it takes for the door to close from 4.1 ft to 0.7 ft:

t = (4.1 - 0.7) / 1.1 = 3.4 / 1.1

t = 3.09 s

Next, let's find the distance Bob has to cover in that time:

d = 42 - 3.4

d = 38.6 ft

Now we can find Bob's speed using the formula:

d = v * t

Solving for v:

v = d / t = 38.6 / 3.09

v= 12.50 ft/s (rounded to the nearest hundredth)

Therefore  Bob needs to run at a speed of 12.50 ft/s in order to catch the elevator.

Answer:

C; both the relation and inverse are functions

Step-by-step explanation:

A function has no more than one output for a specific input, therefore, the original set of points is a function.

To find the inverse, you swap the x and y, so you would get:
(0, -5), (-2, -1), (1, -2), (4, 0), (2, 1), (-1, 2)

The inverse is also a function, because each input has only one output.

The volume of the frustum of a pyramid with square base of side "b", square top of side "a", and height "h" is (b² - a²) × h / 3 cubic units.

The two primary divisions of calculus, differential calculus and integral calculus, are concerned with rates of change and slopes of curves.

A pyramid's frustum can be thought of as two pyramids with the same height "h" and square bases on sides "a" and "b," as well as a square top on side "a" and that height.

The formulas below give the volume of a pyramid with a square base and sides "s" and height "h":

The volume of a pyramid with square base of side "s" and height "h" is given by:

V = (s² × h) / 3

The volume of the frustum can be found by subtracting the volume of the smaller pyramid from the volume of the larger pyramid:

V = [(b² × h) / 3] - [(a² × h) / 3] = (b² - a²) × h / 3

Hence, the volume of the frustum of a pyramid with square base of side "b", square top of side "a", and height "h" is (b² - a²) × h / 3 cubic units.

The value of r'(1) is 112.

To find the derivative of r(x) at x = 1, we'll use the chain rule. The chain rule states that if r(x) = f(g(h(x))), then the derivative of r(x) with respect to x is given by r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x).

When r(x) = f(g(h(x))) by chain rule

r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)

So r'(1) =  f'(g(h(1))) * g'(h(1)) * h'(x)

As h(1) = 2 and h'(1) = 4

r'(1) = f'(g(2)) * g'(2) * 4

As g(2) = 4 and g'(2) = 4

r'(1) = f'(4) * 4 * 4

As f'(4) = 7

How does transfer function work?

A mathematical function called a transfer function of a system, sub-system, or component theoretically simulates the output of the system for each potential input.

                             Transfer functions are also known as system functions or network functions. They are frequently employed in electronic and control systems.

Why is the transfer function only specified for LTI systems?

The ratio between the Laplace transforms of the input and output signals under initial circumstances of zero can be used to define the transfer function of the LTI system.

                              Alternately, when the beginning circumstances are disregarded, the transfer function is described as the output to input ratio in the sdomain.

As the equation of tangent line is y = -3x, the value of slope, m is -3 and value of b is 0.

To find the equation of the tangent line at the point (π, -3π), we need to find the derivative of the function y = 3xcos(x), which is

y' = 3cos(x) - 3xsin(x)

and then evaluate the derivative at x = π to find the slope of the tangent line.

The slope at x = π is

m = 3cos(π) - 3πsin(π) = -3

So, the equation of the tangent line is y = -3x + b.

To find the value of b, we use the point (π, -3π) and the slope -3:

-3π = -3 * π + b

b = 0

So, the equation of the line tangent to the curve y = 3xcos(x) at the point (π, -3π) is y = -3x + 0 or simply y = -3x.

The limit is an important concept in calculus that describes the behavior of a function as the independent variable approaches a specific value.

In this problem, we want to find the limit of the expression (x-3) / (x-9) as x approaches a specific value.

To find the limit, we must substitute values of x that are very close to the specific value and see what the expression approaches.

However, it is important to note that if the limit does not exist, then the function is undefined or has a vertical asymptote at the specific value.

In this case, it is easy to see that the limit does not exist as x approaches 9 because the denominator of the fraction is equal to 0, which is undefined.
