The simple interest is I = $ 303.33  and the amount after 2 months with rate of 13 % is A = $ 14,303.33

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the simple interest be represented as I

Let the amount with simple interest be A = P + I

Now , the principal P = $ 14,000

The rate of interest R = 13 %

The number of months = 2 months

The number of years = 2/12 years

Simple Interest I = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

Simple Interest I = ( 14,000 x 13 x ( 2/12 ) ) / 100

On simplifying the equation , we get

Simple Interest I = $ 303.33

Now , the amount after 2 months = P + I

Amount = $ 14,000 + $ 303.33 = $ 14,303.33

Hence , the interest is $ 303.33

What is the successive differences?

The method of successive differences involves finding the differences between consecutive terms in a sequence and using that information to predict the next term in the sequence.

To use this method for the sequence 3, 7, 17, 33, 55, 83, 117:

Find the differences between consecutive terms:

7 - 3 = 4

17 - 7 = 10

33 - 17 = 16

55 - 33 = 22

83 - 55 = 28

117 - 83 = 34

Check if the differences are constant. In this case, they are increasing by 6 each time.

The smaller number is 15 and the larger number is 36.

Let x and y be the smaller and larger numbers, respectively.

From the given information, we know:

y = x + 21 (because the larger number is 21 more than the smaller number)

x + y = 51 (because the sum of the two numbers is 51)

We can substitute the first equation into the second equation to find the value of x:

x + (x + 21) = 51

x + x + 21 = 51

2x = 30

x = 15

Now that we know the value of x, we can use the first equation to find the value of y:

y = x + 21

y = 15 + 21

y = 36

So the smaller number is 15 and the larger number is 36.

The area of the shaded region is obtained as (π/√2) units².

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

The diagram is labelled.

The values for area of z and y needs to be obtained.

The result will be in the form |y| + z as when the integration will be done, y will come out to be negative.

Now, x + z is the area of rectangle ABCD.

Verify whether x and y are equal in magnitude -

[tex]\begin{aligned}& x=\int_{\frac{\pi}{4}}^{\frac{\pi}{2}} \frac{\cos \theta}{\sin ^2 \theta} d \theta=\left[\frac{-1}{\sin \theta}\right]_{\frac{\pi}{4}}^{\frac{\pi}{2}} \\& =-1-(\sqrt{2}) \\& =\sqrt{2}-1\end{aligned}[/tex]

[tex]\begin{aligned}& y=\int_{\frac{\pi}{2}}^{\frac{3\pi}{4}} \frac{\cos \theta}{\sin ^2 \theta} d \theta=\left[\frac{-1}{\sin \theta}\right]_{\frac{\pi}{2}}^{\frac{3\pi}{4}} \\& =-(\sqrt{2})-(-1) \\& =-\sqrt{2}+1\end{aligned}[/tex]

This is equal to |y| = x.

So, |y| + z is equivalent to writing x + z.

Now the formula for area of rectangle ABCD is -

Area = length × breadth

Area = √2 - [(3π/4) - (π/4)]

Area = √2 - (π/2)

Area = (π/√2)

Answer:To show that Lorenz curves are always concave up on the interval [0, 1], we can use the definition of a Lorenz curve, which is L(x) = xp. Taking the second derivative of L(x) with respect to x gives us L''(x) = p. Since p is always greater than 0, L''(x) is always greater than 0. This means that L(x) is always concave up on the interval [0, 1].

Table of Lorenz values for p = 1.2, 1.5, 2.1, 2.5, 3, and 5:

a. The value of p that corresponds to the most equitable distribution of wealth is 1, as this would mean that the proportion of wealth held by each portion of the population is equal.

b. The value of p that corresponds to the least equitable distribution of wealth is 5, as this would mean that a small portion of the population holds a large proportion of the wealth.

The Gini Index is a measure of income inequality, where a value of 0 represents perfect equality (everyone has the same income) and a value of 1 represents perfect inequality (one person has all the income). The Gini Index is calculated as the ratio of the area between the Lorenz curve and the line of equality to the total area beneath the line of equality.

To find A and B for the Gini index we can use the following integral:

A = ∫(L(x) - x) dx from 0 to 1

B = ∫(x - L(x)) dx from 0 to 1

We can then solve the integral for each specific function of L(x) = xp to find the specific value of A and B.

In circle the length of PQ = 24 inches.

What is Circle?

A circle is a closed, two-dimensional object in which all points in the plane are equally spaced apart from the centre. The line of reflection symmetry is formed by each line that traverses the circle. Additionally, it possesses rotational symmetry around the centre for each angle.

Since AB= 25 inches and AC = 16 inches then

=> BC = AB-AC = 25-16 = 9 inches.

∠APB is a right angle because it is inscribed in a semicircle.

The three right triangles ᐃAPB, ᐃACP and ᐃPCB are all similar

because their corresponding angles are equal.  Therefore

=> [tex]\frac{AC}{PC}=\frac{PC}{BC}[/tex]

=> [tex]\frac{16}{PC}=\frac{PC}{9}[/tex]

=> [tex]PC^2 = 25*9 = 144 = 12^2[/tex]

=> PC = 12 inches

By symmetry , PC = QC then,

=> PQ = 12*2 = 24 inches.

Answer: the answer is 90

Step-by-step explanation:There is only one number between 61 and 107 that is a multiple of 3, 5 and 9. So that number will be  90.

The solution set of the original system is

[tex]$\left[\begin{array}{l}x_1 \\ x_2 \\ x_3 \\ x_4\end{array}\right]=\left[\begin{array}{c}-3 \\ -5 \\ 6 \\ -3\end{array}\right]$[/tex]

Step 1

We are given with a row reduced matrix form.:

[tex]$$M=\left[\begin{array}{rrrrr}1 & -2 & 0 & 3 & -2 \\0 & 1 & 0 & -4 & 7 \\0 & 0 & 1 & 0 & 6 \\0 & 0 & 0 & 1 & -3\end{array}\right]$$[/tex]

We have to find the solution set using the appropriate steps.

Step 2: The Augmented matrix Form

[tex]$$\left[\begin{array}{cccc}1 & -2 & 0 & 3 \\0 & 1 & 0 & -4 \\0 & 0 & 1 & 0 \\0 & 0 & 0 & 1\end{array}\right]\left[\begin{array}{l}x_1 \\x_2 \\x_3 \\x_4\end{array}\right]=\left[\begin{array}{c}-2 \\7 \\6 \\-3\end{array}\right]$$[/tex]

Step 3: System of Equations

[tex]$$\begin{aligned}& x_1-2 x_2+3 x_4=-2 \\& x_2-4 x_4=7 \\& x_3=6 \\& x_4=-3\end{aligned}$$[/tex]

Step 4: The Back-Substitution

From last two rows, we have

[tex]$$\begin{aligned}& x_3=6 \\& x_4=-3\end{aligned}$$[/tex]

Now substitute in row-2, to get value of $x_2$

[tex]$$\begin{aligned}& x_2-4(-3)=7 \\& x_2+12=7 \\& x_2=7-12 \\& x_2=-5\end{aligned}$$[/tex]

Now substitute in row-1, to get value of $x_1$

[tex]$$\begin{aligned}& x_1-2(-5)+3(-3)=-2 \\& x_1+10-9=-2 \\& x_1+1=-2 \\& x_1=-3\end{aligned}$$[/tex]

So,

[tex]$\left[\begin{array}{l}x_1 \\ x_2 \\ x_3 \\ x_4\end{array}\right]=\left[\begin{array}{c}-3 \\ -5 \\ 6 \\ -3\end{array}\right]$[/tex]

AB multiplication of two matrices

multiplication of two matrices is possible only when B has the same number of columns as rows in A,

If it is defined as above, then the matrix AB will have m rows and p columns, i.e., A must have n columns and B must have n rows in order for AB to be defined.

This is a classic problem where we are asked to find such an integer that is going to be a divisor of the above set S of integers. The set S of integers consists of those integers that when squared are both divisible by 24 and 108. Now we know 24 can be written as 2*2*2*3 and similarly 108 can be written as 2*2*3*3*3. The smallest perfect square (n^2) which is a multiple of both 24 and 108 is 2^4*3^4, thus the smallest n is 2^2*3^2 = 36. So, only 12 is a divisor of all integers in S.

A function with an infinite number of critical points can be expressed as a continuous function with a derivative that is equal to zero at every point in its domain.

For example, the function f(x) = 0 has an infinite number of critical points since its derivative f'(x) = 0 for every x in its domain. Alternatively, a function that has every point as a critical point can be expressed as a function with a derivative that is always equal to zero. For example, the constant function f(x) = c has a derivative f'(x) = 0 for every x in its domain, and thus every point in its domain is a critical point.

In addition, an example of a function with every point as a critical point is the constant function, f(x) = c, where c is a constant. The derivative of this function is f'(x) = 0, which means that the derivative is zero for all values of x. Therefore, every point of the constant function is a critical point.
