Answer:

The correct answer is B. 20,000

Step-by-step explanation:

To determine the man's total monthly salary, we can set up a simple equation using the given information. Let's denote the total monthly salary as "x."

According to the information provided, 33% of the man's monthly salary is equal to Birr 6600. We can express this relationship mathematically as:

0.33x = 6600

To solve for "x," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.33:

x = 6600 / 0.33

Evaluating the right side of the equation gives:

x ≈ 20,000

Therefore, the man's total monthly salary is approximately Birr 20,000.

Hence, the correct answer is B. 20,000.

The solubility of BaCrO4 in a 0.0180 M BaCl2 solution is 6.50 x 10^-6 M.

We are given that;

Temperature= 25

bacl2 solution= 0.0180

Now,

In a 0.0180 M BaCl2 solution, we have to consider that some of the Ba2+ ions come from the BaCl2 salt, which is highly soluble and dissociates completely in water. Therefore, the concentration of Ba2+ in the solution is not equal to x, but rather 0.0180 + x. The concentration of CrO4^2- is still equal to x, since it only comes from the dissolution of BaCrO4. Then we have:

Ksp = (0.0180 + x)x

Solving for x, we get:

(0.0180 + x)x = 1.17 x 10^-10 x^2 + 0.0180x - 1.17 x 10^-10 = 0 Using the quadratic formula, we get: x = [-0.0180 ± √(0.0180^2 + 4(1.17 x 10^-10))] / 2 x ≈ -0.0180 or x ≈ 6.50 x 10^-6 M

We reject the negative value of x, since it does not make sense for a concentration to be negative.

Therefore, by the solution the answer will be 6.50 x 10^-6 M.

True. Pointer arithmetic is a way of performing arithmetic operations on pointers, which are variables that hold memory addresses.

When a pointer points to a specific element in an array, the value of the pointer is the memory address of that element. If we add or subtract an integer value n to the pointer using the arithmetic operators + or -, the resulting pointer points to an element that is n positions away from the original element in the array.
For example, if we have an array of integers and a pointer ptr that points to the first element of the array, then ptr + 2 would point to the third element of the array because we added 2 to the memory address of the first element. Similarly, ptr - 1 would point to the last element of the array, because we subtracted 1 from the memory address of the first element.
It's important to note that pointer arithmetic is only valid within the bounds of the array. If we try to access memory outside of the array, we may get undefined behaviour or a segmentation fault. It's also important to be careful when using pointer arithmetic, as it can be easy to introduce bugs if we don't keep track of the size and type of the elements in the array.

The distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

To find the distance between successive fourth roots of a complex number on the unit circle, we can use the concept of the angle between the roots. Let's proceed step by step:

The given complex number is √3/2 - 1/2i. This complex number lies on the unit circle because its magnitude is equal to 1.

1. Convert the given complex number to trigonometric form:

  √3/2 - 1/2i = cos(θ) + i*sin(θ)

  By comparing the real and imaginary parts, we can determine the angle θ:

  cos(θ) = √3/2

  sin(θ) = -1/2

  Using the unit circle, we can find that θ = 5π/6 (or 150 degrees). This angle represents the position of the given complex number on the unit circle.

2. Find the angle between successive fourth roots:

  Since we are interested in the fourth roots, we divide the angle θ by 4:

  θ/4 = (5π/6) / 4 = 5π/24

  This angle represents the angular distance between two successive fourth roots on the unit circle.

3. Calculate the distance between the two points:

  To find the distance, we multiply the angular distance by the radius of the unit circle (which is 1):

  Distance = (5π/24) * 1 = 5π/24

  Therefore, the distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

The hypercube Q3 has eight vertices labeled by the binary sequences 000, 001, 010, 011, 100, 101, 110, and 111. In graph theory, a cycle of length 4 is referred to as a 4-cycle.

Since we want to know how many 4-cycles the vertex 000 is involved in the hypercube Q3, we can proceed as follows:

Step 1: Find the neighbors of vertex 000.

In the hypercube Q3, two vertices are adjacent (or neighbors) if and only if their binary representations differ in exactly one bit position.

Therefore, the neighbors of 000 are 001, 010, and 100.

Step 2: Consider the subgraph induced by the neighbors of 000.

This subgraph is a cube Q2, which is also known as a square.

The vertices of Q2 are labeled by the binary sequences 001, 010, 100, and 101.

The edges of Q2 are the same as the edges of the hypercube Q3 that connect the vertices in this subgraph.

Step 3: Count the number of 4-cycles in the subgraph Q2.

Since Q2 is a 2-dimensional hypercube, it is easy to visualize that there are four 4-cycles in this graph, as shown below:

Image credit: Wolfram Math World.

Step 4: Extend each 4-cycle in Q2 to a 4-cycle in Q3 that involves vertex 000.

To do this, we simply add 000 as a fifth vertex to each 4-cycle in Q2, and connect it to each of the four vertices in the cycle.

There are four such 4-cycles in total, one for each 4-cycle in Q2.

Therefore, the vertex 000 is involved in four 4-cycles in the hypercube Q3.

Answer:

C, or the third one

Step-by-step explanation:

The equation of the line passing through the points (-2, 3) and (5, 4) is y = (1/7)x + 23/7.

A straight line is a geometric object that extends infinitely in both directions and has no curvature or angles. It can be defined as the shortest distance between two points in a two-dimensional plane. A straight line can be represented algebraically using the slope-intercept form:

y = mx + b

To find the equation of a line passing through two given points, we can use the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

where m is the slope of the line and (x₁, y₁) is one of the given points.

First, we need to find the slope of the line passing through the points (-2, 3) and (5, 4). We can use the slope formula:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (-2, 3) and (x₂, y₂) = (5, 4):

m = (4 - 3) / (5 - (-2))

m = 1/7

Now we have the slope of the line, we can use one of the given points to write the equation in point-slope form. Let's use the point (5, 4):

y - y₁= m(x - x₁)

y - 4 = (1/7)(x - 5)

To convert this equation into slope-intercept form (y = mx + b), we can simplify and solve for y:

y - 4 = (1/7)x - (5/7)

y = (1/7)x - (5/7) + 4

y = (1/7)x + 23/7

Therefore, the equation of the line passing through the points (-2, 3) and (5, 4) is y = (1/7)x + 23/7.

Step-by-step explanation:

let the 3 consecutive numbers be n , n + 1 and n + 2 , then

n + n + 1 + n + 2 = 108

3n + 3 = 108 ( subtract 3 from both sides )

3n = 105 ( divide both sides by 3 )

n = 35

and

n + 1 = 35 + 1 = 36

n + 2 = 35 + 2 = 37

the 3 numbers are 35, 36, 37

The next three terms in the sequence are 116 , 159 and 209

We are supposed to find the next 3 terms in the sequence:

5, 6, 14, 29, 51, 80, ___, ___, ___.

Here we can are first supposed to find the pattern which is as follows:

\(6-5=1\\14-6=8\\29-14=15\\51-29=22\\80-51=29\\\)

Therefore difference between the numbers is 7 more than the previous one i.e,

\(1+7=8\\8+7=15\\15+7=22\\22+7=29\)

Let required three numbers be x, y and z

So \(x-80=29+7=36\\x=116\)

    \(y-116=36+7=43\\y = 159\)

and \(z-159=43+7=50\\z=209\)

Integration is a fundamental concept in calculus, which is used to find the area under a curve and the total change of a function. It is the reverse process of differentiation and can be used to find the original function, given its derivative.

For f(x) = 5 for x < 5, we have

∫(5dx) from 0 to 5 = 5*(5-0) = 25

For f(x) = x for x ≥ 5, we have

∫(x dx) from 5 to 9 = (1/2)x^2 from 5 to 9 = (1/2)(9^2 - 5^2) = (1/2)(81 - 25) = (1/2)(56) = 28

So the definite integral of the piecewise function is

∫(9 f(x) dx) from 0 to 9 = ∫(5dx) from 0 to 5 + ∫(x dx) from 5 to 9 = 25 + 28 = 53,
