The limit of a function is a value of the function as the input of the function gets closer to some number.

We know that, a limit is a value toward which an expression converges as variable approaches certain values.

The limit of a function at m point is nothing but the value that the function approaches as its argument(variable) approaches m.

When a function is said to have a limit L at point p if it is possible to make the function arbitrarily close to L by choosing values to point p.

It is a value of the function as the input of the function gets closer to some number.

Therefore, the limit of a function is nothing but a value of the function as the input of the function gets closer to some number.

The force that it will take if applied perpendicular at 30° = 58 N

According to the formula of torque = τ and force = F,

τ =  r x F x sinθ --- equation 1

Given, F = 100 N , r = 0.2 m (r = radius)

We have to find the force when θ (angle) = 30°

Putting value in equation 1,

τ = 0.2 x 100 x sin (30°)

τ = 10 Nm

Value of torque from here = 10 Nm

Now to calculate the force perpendicular at 30° the equation will change as,

τ = r x F x cosθ --- equation 2

10 = 0.2 x F x cos 30°

Taking τ on the right side and F on left,

F = 10/ (0.2 x cos 30°)

F = 57.73 N

F = 58 N

Mean is the average of a set of values. It is calculated by adding up all the values in the set and dividing by the number of values in the set.

Median is the middle value of a set of values. It is calculated by arranging all the values from smallest to largest and then finding the middle value in the set. Mean and median are used to measure the center of a set of values. Mean and median are often used to identify trends and patterns in data sets, as they are useful in describing the “average” or “typical” value of a set of data. They are also used in hypothesis testing and various statistical tests.

Answer:-3/4x=-3x/4

4/3x -3/7 = 4x/3 - 3x

Step-by-step explanation:

Answer:

Vertex = (5,0)

Axis of symmetry = x = 5

Explanation:

Y = 3(x-5)^2

Equal 3(x-5) to 0

y = 3 = 0

x-5 = 0

x = 5

Vertex = (5,0)

Formula for Axis of symmetry: x = -b/2a

Write 3(x-5)^2 in standard form

Y = 3x^2 - 30x + 75

x = -b/2a

x = -(-30)/2(3)

x = 30/6

x = 5

Step-by-step explanation:

The equation of a parabola with focus at (h, k) and the directrix y = p is given by the following formula:

(y - k)^2 = 4 * f * (x - h)

In this case, the focus is at the origin (0, 0) and the directrix is the line y = -1.3, so the equation representing the cross section of the reflector is:

y^2 = 4 * f * x

  = 4 * (-1.3) * x

  = -5.2x

The depth of the reflector is the distance from the vertex to the directrix. In this case, the vertex is at the origin, so the depth is simply the distance from the origin to the line y = -1.3. Since the directrix is a horizontal line, this distance is simply the absolute value of the y-coordinate of the line, which is 1.3 inches. Therefore, the depth of the reflector is approximately 1.3 inches.

In the question ,

it is given that ,

the length of the model train is = 18 inches   and

the length of the exact train is = 72 feet ,

on comparison , we need to convert it into inches .

we know that 1 feet is = 12 inches ,

So , 72 feet is = 72×12 inches = 864 inches

So , the length of the original train is = 864/18 = 48 times the model train .

the ratio will remain same for the width of the window .

So , the window on the train is 48 times wider than a window on the model .

The limiting matrix is [tex]\bar{P}[/tex]=[tex]\left[\begin{array}{ccc}0.75&0.25\\0.75&0.25\\\end{array}\right][/tex].

Mathematicians frequently refer to "transition matrices" in a variety of situations. The term "change of coordinates matrix" is occasionally used in the context of linear algebra. As an alternative term for a stochastic matrix, or a matrix that describes transitions, it is employed in the theory of Markov chains. Use row operations to try to create the identity matrix to the left while augmenting the matrix of the second basis with the matrix of the first basis. Afterward, the transition matrix will be on the right. Row 1 should be multiplied by 1 as follows: R1=R1 R 1=-R 1 R1=R1.

Answer:

To find the area of a parallelogram, we can use the formula A = bh, where A is the area, b is the base, and h is the height. In this case, we are given that the area is 60 square units, so we can use this information to find the value of b and h for each of the options given.

Option A: 12 15 10

In this option, we can see that the base is 12 units and the height is 15 units, so we can plug these values into the formula to find the area: A = 12 * 15 = 180 square units. This is much larger than the given area of 60 square units, so option A cannot be correct.

Option B: 10 10.2 6

In this option, we can see that the base is 10 units and the height is 6 units, so we can plug these values into the formula to find the area: A = 10 * 6 = 60 square units. This matches the given area of 60 square units, so option B could be correct.

Option C: 15 15 12

In this option, we can see that the base is 15 units and the height is 12 units, so we can plug these values into the formula to find the area: A = 15 * 12 = 180 square units. This is much larger than the given area of 60 square units, so option C cannot be correct.

Option D: 6 6 10

In this option, we can see that the base is 6 units and the height is 10 units, so we can plug these values into the formula to find the area: A = 6 * 10 = 60 square units. This matches the given area of 60 square units, so option D could be correct.

To complete the triangle, you would need to bend the other end of the strip of metal so that it is also 10 inches from the first bend. One way to do this would be to measure 10 inches from the first bend and mark the spot, then use a bending tool to carefully bend the metal at the mark.

Another way would be to hold the metal strip against a ruler or measuring tape, aligning the first bend with the 10-inch mark, then use the bending tool to make the second bend at the 20-inch mark. In either case, the resulting triangle would have two equal sides that are 10 inches long, and a base that is 8 inches long.

The graph

On the graph, we have the following data values for reservation

The total number of reservations in the bar chart is then calculated as

Total number of reservations = 5 + 3 + 4 + 7 + 26 + 30 + 9

When two consecutive lines or rays intersect at a single endpoint, an angle is created.

The vertex of an angle is the point where two points come together.

The Latin word "angulus," which means "corner," is from which the term "angle" originates.

The intersection of two planes also creates angles.

We refer to these as geometric angles.

So, according to the given diagram:

KMN = LMN + 118

180 = LMN + 118

LMN = 180 - 118

LMN = 62°

Now,

6x - 9 + 4x + 7 + 62 = 180

10x + 60 = 180

10x = 180 - 60

10x = 120

x = 120/10
