The ratio of the volume of the triangular prism to the volume of the cuboid is 1:2.

The volume of a triangular prism is calculated by multiplying the area of the base by the height of the prism. The volume of a cuboid is calculated by multiplying the length, width, and height of the cuboid.

For a triangular prism with base area A and height h, the volume is A x h.

For a cuboid with length l, width w, and height h, the volume is l x w x h.

Therefore, the ratio of the volume of the triangular prism to the volume of the cuboid is A x h : l x w x h, which simplifies to 1:2.

Independent of the input, the transfer function. In cases when the input is not a complex exponential, you are probably interested in the result. The answer is that the output can be computed via convolution as long as the input satisfies certain constraints .

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.

Integration is the process of calculating an integral. Integrals are used by mathematicians to compute a range of useful quantities, such as areas, volumes, displacement, etc. Usually, when we talk about integrals, we mean definite integrals. Indefinite integrals are used for antiderivatives. Integration is one of the two primary calculus topics in mathematics, along with differentiation (which measure the rate of change of any function with respect to its variables).

An integral that has both the upper and lower boundaries is said to be definite. Only a real line may be used for X to lay. A Riemann Integral is another name for the Definite Integral.

∫f(x)dx from a to b.

The definition of integrals without upper and lower bounds. It appears as follows:

A definite Integral is represented as:

∫f(x)dx = F(x) + C

Where C is any constant and the function f(x) is called the integrand.

Now,

Right expression is

[tex]\frac{dS}{dt} = 8sin^{2}(t+\frac{\pi}{12} )[/tex]

The limit of (x-3) / (x-9) as x approaches 9 does not exist due to the undefined value in the denominator.

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.

The fraction becomes undefined at x = 9 and the limit does not exist.

The corresponding angles must be equal for the transversal to join two parallel lines.

In the intersection of two parallel lines and a transversal, corresponding angles are created. The opening and closing of a lunchbox, completing a Rubik's cube, and endless parallel railroad tracks are a few examples of matching angles in daily life.

The angles in the same corners of two lines, which are typically parallel, are referred to as corresponding angles when they cross each other across a plane (a transversal). In two separate shapes, corresponding sides and angles refer to a pair of matching sides or angles that are in the same location.

Every matching angle is not created equally. The transversal must connect two parallel lines in order for the corresponding angles to be equal. The equivalent angles that are created when a transversal encounters a line that is not parallel are not congruent and have no connection to one another.

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 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

r'(1) = 7 * 4 * 4

r'(1) = 112

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.

Answer:

This is what I found, but not sure if it's right.

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.

The basis for the nullspace is the set {(-3,1,0,1), (0,1,0,0)}.

The basis for the nullspace of the matrix can be found by reducing the augmented matrix to row echelon form and finding the free variables. The free variables correspond to the columns that have a leading entry of 0 and non-zero entries below it, which are the basis vectors for the nullspace.

Using row operations, the augmented matrix can be reduced to:

1  2 -4  5 | 0

0  1 -3  2 | 0

0  0  0  0 | 0

From this, we can see that the free variables are x2 and x4, so the basis for the nullspace is:

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%
