Answer:

Rs 12

Step-by-step explanation:

According to what I have understood;

13/100*4000= Rs Rs 512

So, Rs 4000 plus its VAT is

4000+ 512= Rs 4512

Then we need to find the difference, That is

Rs 4512 - Rs 4000= Rs 12

Given an exponential function f(x) where

f(-1) = 26 and

f(6.5) = 14.

We have to determine the value of f(5), rounded to the nearest hundredth.

An exponential function can be represented as f(x) = ab^x where a and b are constants.

We need to find the values of a and b.

Let's start with f(-1) = 26:

f(-1) = ab^-1

⇒ 26 = a/b. ......(1)

Similarly, f(6.5) = 14:

f(6.5) = ab^6.5

⇒ 14 = ab^6.5 .......(2)

Let's divide equation (2) by equation (1) to find the value of b.

14/26 = (ab^6.5)/(a/b)

⇒ 0.54 = b^6.5

⇒ b = 0.9196

Substitute this value of b in equation (1) to find the value of a:

26 = a/0.9196

⇒ a = 23.90

Therefore, the equation of the exponential function is

f(x) = 23.90 × (0.9196)^x.

To find f(5), substitute x = 5:

f(5) = 23.90 × (0.9196)^5

≈ 15.15

In the given problem, we are given an exponential function, f(x) where

f(-1) = 26 and

f(6.5) = 14

and we are required to find the value of f(5), rounded to the nearest hundredth

Thus, the value of f(5) is approximately equal to 15.15, rounded to the nearest hundredth.

In the given problem, we have successfully found the value of f(5), rounded to the nearest hundredth. We used the formula of the exponential function f(x) = ab^x and solved the equations to find the values of a and b. Finally, we substituted x = 5 in the equation to find the value of f(5).

Hello,

A.i. the circumference of a circle is nothing else but its perimeter which formula is π × diameter = π × 2 × radius

Let π = 22/7 ≈ 3.142857, the egyptian approximation

Then if C is the circumference of the circle i., C = 22/7 × 21 = (22 × 21) / 7 = (22× 7×3 )/7 = 22 ×3 = 66 cm

ii. Applying the same formula for the second circle gives us C = 22/7 × 8 = 176/7 ≈ 25.14 meters, rounded to the nearest hundredth...

Good luck !

Answer:

a) 66cm.       b) 50.28cm. or 50 2/7cm.

Step-by-step explanation:

The circumference of a circle is C=2πr or C=πd.

π=22/7

a)  C=πd

Plugin the diameter.

C=22/7 x 21

=66cm.

b) C=2πr

Plugin the radius.

C=2 x 22/7 x 8

=50.28cm. or 50 2/7cm.

Answer:

If two figures have the same size and shape, then they are congruent. so if they have the same shape and size even if they are flipped or mirrored they are congruent.

Step-by-step explanation:

The term congruent is often used to describe figures like this, the pictire below. if you look up congruent shapes and look at many examples that will definitely help you understand alot more better what congruent means.

The value of each measure, rounded to the nearest degree, is \(\boxed{115^\circ}\).

The measure of an angle between a tangent and a chord drawn from the point of contact is equal to half the measure of the intercepted arc.

Determine the value of each measure, rounding your answer to the nearest degree.

Two lines tangent to a circle are presented in the figure below:

\(\text{AB}\) and \(\text{CD}\).

In the first step, it is necessary to connect the points where the tangents intersect to form a chord.

\(\text{AC}\) and \(\text{BD}\) are both chords that pass through the circle.

Let \(\text{m}\widehat{\text{C}}=\text{x}\) and

\(\text{m}\widehat{\text{D}}=\text{y}\).

In accordance with the theorem, the following can be written:

\(\text{m}\widehat{\text{A}} =\frac{1}{2}(\text{x}+\text{y})\)

\(\text{m}\widehat{\text{B}} =\frac{1}{2}(\text{x}+\text{y})\)

Therefore, \(\text{m}\widehat{\text{A}}=\text{m}\widehat{\text{B}}\)

There are a few other results as well. Therefore, we have

\(\text{m}\widehat{\text{ACB}}=\text{m}\widehat{\text{A}}+\text{m}\widehat{\text{B}}[/tex

\(\text{m}\widehat{\text{ACB}}=2\times\frac{1}{2}(\text{x}+\text{y})\)\(\text{m}\widehat

{\text{ACB}}=\text{x}+\text{y}\)

Accordingly, the value of each measure is

\(\text{m}\widehat{\text{ACB}}=\text{x}+\text{y}=45^{\circ}+70^{\circ}=115^{\circ}\).

Markov chain model with periodic classes of states can be exemplified by a weather model and ergodic system in a Markov chain is the game of Monopoly.

Example of Markov chain with periodic classes of states:

One example of a Markov chain model with periodic classes of states is a weather model that includes seasonal variations. Let's consider a simplified model with three states: sunny, cloudy, and rainy. In this model, the weather is observed over a long period of time, and it is known that the weather tends to follow a cyclic pattern, transitioning from one season to another. The stochastic matrix representing this Markov chain will have non-zero probabilities for transitions between states within the same season (e.g., sunny to sunny, cloudy to cloudy, rainy to rainy), but zero probabilities for transitions between states in different seasons (e.g., sunny to rainy, rainy to cloudy). This creates periodic classes or groups of states that correspond to the different seasons, resulting in a Markov chain with periodic behavior.

Example of ergodic system in a Markov chain:

A common example of an ergodic system in a Markov chain is the game of Monopoly. In Monopoly, players move around the board based on the outcome of rolling dice. The states in this Markov chain correspond to the positions on the board. Each roll of the dice determines the transition probabilities from one state (position) to another. In an ergodic system, it means that it is possible to reach any state from any other state in a finite number of steps. In the context of Monopoly, this means that players can move from any position on the board to any other position by rolling the dice and following the game rules. The stochastic matrix for this Markov chain will have non-zero probabilities for transitions between all states, reflecting the possibility of moving to any position on the board from any other position.

In summary, a Markov chain model with periodic classes of states can be exemplified by a weather model that represents the cyclic nature of seasons, while an example of an ergodic system in a Markov chain is the game of Monopoly, where players can reach any position on the board from any other position through successive dice rolls and gameplay.

Answer:

52

Step-by-step explanation:

the total is 180

so u add 61 and 67 which gives u 128

so u subtract 180 and 128 which gives u 52

hope this helps

Answer:the answer is 52

Step-by-step explanation:

First a triangle equals 180 degrees. Knowing that Q is 67 degrees and R is 61 degrees 67 plus 61 is 128. 180 subtract 128 is 52 therefore S is 52 degrees.

The width of the rectangular walkway is 3 feet around.

The walkway has a uniform width around the rectangle.

Let the width of walkway be x

The total length of the garden and walkway will be (12+2x) feet

The total width of the walkway and garden would be (8+2x) feet

Area of the garden and the walkway together are 252 square

Let’s express this mathematically:

(8+2x)(12+2x) = 252

Let’s open the brackets;

96+ 16x+ 24x + 4x^2 = 252

4x^2 + 40x + 96 = 252

4x^2 + 40x + 96-252 = 0

4x^2 + 40x - 156 = 0

Let’s divide all through by 10. We have;

x^2 + 10x -39 = 0

X^2 +13x-3x-39 = 0

x(x + 13) -3(x+ 13) = 0

(x-3)(x + 13) = 0

x -3 = 0 or x + 13 = 0

x = 3 or -13

We ignore x = -13 since width cannot be negative in size

Therefore, the width of the rectangular walkway is 3 feet around.

The given row reduced matrix contains an error in the last row, specifically the fourth entry. It should be 0, but it is incorrectly shown as 1. This discrepancy suggests that a mistake occurred during the row reduction process.

Row reduction is a technique used to transform a matrix into its row echelon form or reduced row echelon form. It involves applying elementary row operations to manipulate the matrix's rows. However, errors can occur during the process, leading to incorrect results.

To check for mistakes in row reduction, one can examine the linear combinations of columns in the reduced matrix. Each column represents a vector, and the coefficients in the linear combinations indicate the relationships between these vectors. If the linear combinations do not yield the correct results, it suggests that an error was made during the row reduction.

In the given example, the linear combination in the fourth column of the reduced matrix does not produce the expected result, indicating a mistake. It is crucial to review and verify row reduced matrices using such checks to identify and correct any errors before submitting the final work.

Answer:

It should be D.

Step-by-step explanation:

To find the size of the shift from f to g, compare their corresponding points. To plot a function shifted half as much as g from f, use half of the shift value and plot the points using the same x-values as g.

To determine the size of the shift from function f to function g, you can compare their corresponding points. The shift is equal to the difference in the y-values of the corresponding points. To plot a function that is shifted only half as much as g from the parent function f, you need to take half of the shift value obtained earlier. This will give you the new y-values for the shifted function. Use the same x-values as used in the table for function g. Plot the points with the new y-values and the same x-values, and you will have the graph of the shifted function.

The correct option is the third one; (14, 4); The vertex represents the maximum profit.

For a general quadratic equation

y = ax² + bx + c

The vertex is at the x-value:

x = -b/2a

Here the quadratic function is:

f(x)=  -x² + 28x - 192

The vertex is at:

x = -28/2*-1 = 14

Evaluating in x= 14 we get:

f(14) = -14² + 28*14 - 192 = 4

So the vertex is at (14, 4), and because the leading coefficient is negative, this is the maximum profit.

Answer:

So the slope in this case is m = -2. Using point (0, 7) and m =-2 with point-slope we have y - 7 = -2(x-0) => y = -2x +7. Then we realize (0,7) actually is the y-intercept. We could have gone directly to y = -2x + 7. If we use (3,1) and m = -2 we get y-1=-2(x-3) => y -1 = -2x+6 => y = -2x+7. Another way to find y-intercept is to use y = mx +b directly. If we use the point (3,1) that means when x=3, y = 1. So 1=-2(3) + b => 1=-6+b => b = 7. So, y = -2x+7. Same result in all cases. I like to use point-slope. Others prefer to use y = mx+b, substituting for x, y, and m to solve for b.

The answers, rounded to the appropriate number of significant figures, are as follows:

(a) 1.088 ×\(10^2\)

(b) 2.132

(c) 1.3331 ×\(10^1\) and

(d) 1.05.

Let's calculate the answers to the given operations using the appropriate number of significant figures.

(a) 8.370×1.3×10

To perform this multiplication, we multiply the decimal numbers and add the exponents of 10:

8.370 × 1.3 × 10 = 10.881 × 10 = 1.0881 × \(10^2\)

Since the original numbers have four significant figures, we round the final answer to four significant figures:

1.088 × \(10^2\)

(b) 4.265/2.0

The study of hypnosis and its relationship to hysteria was the starting point for the development of psychoanalysis by Sigmund Freud.

The study of hypnosis and hysteria in the late 19th century by Sigmund Freud and his contemporaries led to the development of psychoanalysis, a form of psychotherapy that emphasizes the role of unconscious thoughts and feelings in shaping behavior. Through his work with patients suffering from hysteria, Freud became interested in the idea that psychological conflicts could be traced back to early childhood experiences, and that these conflicts could be resolved through the exploration of unconscious thoughts and feelings. This eventually led to the development of psychoanalysis as a theory and practice for the treatment of psychological disorders.
