A Gaussian function in mathematics is a function with the base form and parametric extension for all real constants a, b, and c that are not zero. This function is frequently referred to as a Gaussian. It bears the name of the mathematician Carl Friedrich Gauss. A Gaussian's graph has the recognizable symmetric "bell curve" shape. The parameters a and b determine the height and location of the curve's peak, respectively, while the parameter c, also known as the standard deviation or Gaussian RMS width, determines the width of the "bell." Gaussian functions are frequently used in statistics to characterize the normal distributions, in signal processing to build Gaussian filters, and in image processing where two-dimensional Gaussians are utilized for Gaussian blurring.

The mass of gas contained in the tank is 42.525 g. It is calculated using the concept of density and volume of a substance.

What is density?

Density is generally defined as the mass per unit volume. Its representation is done using the symbol p. SI unit of density is kg / (m)3.

Calculation of the total mass of gas contained in the rectangular tank

Given:

Length of the rectangular tank, l = 27 cm

Breadth of the rectangular tank, b = 7 cm

Height of rectangular tank, h = 11.25 cm

Volume of rectangular tank = l × b × h

= 27 × 7 × 11.25

= 2,126.25 cubic cm

Density = 0.020 g/ml         (1 ml = 1 cubic cm)

Mass / Volume = 0.020

Mass = 0.020 × 2,126.25

= 42.525 g

Hence, the mass of gas contained in the tank is 42.525 g.

The simplest form of the ratio 35:30 is 7/6.

Given, the ratio is 35:30

By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other. There are two different categories for ratios. The first is a part to part ratio, whereas the second is a part to whole ratio. The relationship between two separate entities or organizations is shown by the part-to-part ratio.

We can refer to a fraction as being in its simplest form when it cannot be further spelled out or reduced. Divide the denominator and numerator by their respective least common multiples to reduce a fraction.

divide the numbers by 5

Answer:

k = -10

Step-by-step explanation:

(-8-3k)/2 = 11

Multiplying both sides with 2:

2{(-8-3k)/2} = 11(2)

-8-3k = 22

-8-3k+8 = 22 + 8

-3k = 30

k = 30/-3

k = -10

Check:

(-8-3k)/2 = 11

Putting the value of k that is -10:

{-8-3(-10)}/2 = 11

(-8+30)/2 = 11

22/2 = 11

11 = 11

Hence, it is proved that, k is, in fact, equal to -10

Make sure your calculator is in Degree mode.

a) The area of rectangle ABCD in terms of x and y = 4xy.

b) xy = 10

c) area of triangle EBF​ = 5 m².

Part A) The area of rectangle ABCD:

See the diagram;

The length of rectangle is 2x.

The width of breadth is 2y.

Area = length×breadth

Area = 2x × 2y

Area of ABCD = 4xy m².

Part b) value of xy.

The area of the triangle DEF is 15m².

area ΔDEF = area ABCD - area ΔADE - area ΔBEF - area ΔDFC.

Put the values;

area ΔDEF = 4xy - 2xy/2 - 2xy/2  - xy/2

area ΔDEF = 3xy

equate;

ΔDEF = 3xy and DEF = 15m².

3xy/2 = 15

xy = 10

Thus, the value of xy = 10.

Part c) area of triangle EBF​:

area ΔEBF = xy/2

Put the value of xy = 10.

area ΔEBF = 10/2  = 5

Thus, the area of the triangle EBF 10m².

The base of the triangle is 9 2/11 cm.

Given the height of the triangle is = 2 3/4 cm

area of the triangle is = 12 5/8 cm²

we know the area of the triangle is = 1/2 × b × h

but base = ?

therefore, 12 5/8 cm² = 1/2 × b × 2 3/4 cm

convert improper fraction to proper fraction.

101/8 = 1/2 × b × 11/4

101/8 = 11b/8

like terms gets cancelled

101 = 11b

b = 101/11

b = 9 2/11 cm

Hence we get the base of the triangle as 9 2/11 cm.

Step-by-step explanation

The van can carry 13 students and the bus can carry 53 students.

A van can carry = 13

A bus can carry = 53

The equations will be derived from the conditions given in the question:

Let x be the no. of students in van

Let y be the no. of students in bus

     13x + 9y = 646……………(1)

      6x + 3y = 237………………(2)

Multiplying (2) with 3

13x + 9y = 646……………(3)

18x + 9y = 711 …………...(4)

Subtracting equation (3) from (4)

18x + 9y = 711

- (13x + 9y = 646)

We get:

5y = 65

y = 13

Now, plug the value of y into one of the preceding equations:

13x + 9(13) = 646

Solving this we get

x = 53

Hence, The van can carry 13 students and the bus can carry 53 students

The component form of a vector refers to breaking the vector into components with unit vectors denoting the direction of each component. The general component form angled vectors in a two-dimensional space is given by:

[tex]\vec v=|v|cos\theta\hat{x}+|v|sin\theta\hat{y}[/tex]

where |v| is the magnitude of the vector component and theta is the angle of the vector.

Using the magnitude and angle given for vector u we can write its component form :

[tex]\vec u=|u|cos\theta_u \hat{x}+|u|sin\theta_u \hat{y}\\\vec u=|5|cos(9)\hat{x}+|5|sin\(9) \hat{y}\\\vec v=5cos9_u\hat{x}+5sin9_u\hat{y}[/tex]

Doing the same for v

[tex]\vec v=|v|cos\theta_u \hat{x}+|v|sin\theta_u \hat{y}\\\vec v=|1|cos5_u \hat{x}+|1|sin5_u \hat{y}\\\vec v=1cos5_u\hat{x}+sin5_u\hat{y}[/tex]

Answer:

Function A is a function because the inputs on the table do not repeat any number, implying that each input has exactly one output. Function B is not a function because the inputs show that the number 6 is repeated. Function C is not a function because if we make a table, we can see that numbers repeat on the input, so Function C is not a function. Function D is a function because it would pass the vertical line test because no lines overlap with each other or have the input repeating.

Using the function concept, it is found that relations b and c does not represent a function.

A relation represents a function when each value of the input is mapped to only one value of the output.

On a graph, it means that each value of x is mapped to only one value of y, that is, there are no vertically aligned points on the graph.

For this problem, relation c does not represent a function, as there are multiple values of x are related to two values of y, and there are vertically aligned points on the graph.
