The first equation VI - IV = IX is incorrect and can be corrected to VI + IV = X by shifting one matchstick from the minus sign to the equals sign. The second equation I - III = II is also incorrect and can be corrected to I = III - II by shifting the one matchstick from the equals sign to the minus sign.

Matrix transapose in c++
The document discusses the history and definition of matrices. It states that the true mathematical use of matrices was first formulated in 1850 by English mathematician James Sylvester. It then defines a matrix as a rectangular array of numbers or symbols arranged in rows and columns.
Math1000 section1.6
This document introduces complex numbers and how to perform basic operations with them. Complex numbers were created to account for negative numbers under a square root. The imaginary unit is i = √-1. Complex numbers are written in the form a + bi. To add or subtract complex numbers, simply add or subtract the real and imaginary parts separately. To multiply complex numbers, use FOIL and note that i^2 = -1. To divide complex numbers, multiply the numerator and denominator by the complex conjugate of the denominator. Complex numbers arise when solving quadratic equations using the quadratic formula.
Alg2 lesson 5-9
i is an imaginary number defined as the square root of -1. A complex number combines a real part and an imaginary part and is written in the form a + bi, where a is the real part and bi is the imaginary part. To simplify complex expressions, combine like real and imaginary terms.
Answers for m ath practice for 2 period exam
This document provides answers to a math practice exam for 2nd period students at Colegio San Patricio for the 2010-2011 school year. It covers topics like numbers, tree diagrams, proportions, scale drawings, geometry, angles, and key terms. For example, it explains how to calculate the number of math problems remaining if 3 out of 24 problems were completed. It also defines terms like line segment, mediatriz, apotema, and bisectriz.

2.8 coord. plane 1
The document provides examples and explanations for using the coordinate plane:
- It defines the key elements of the coordinate plane including the x-axis, y-axis, origin, quadrants, and ordered pairs used to identify points.
- An example shows how to plot the point (4, -2) by moving right 4 units and down 2 units from the origin.
- Another example solves a multi-step problem to find the perimeter of a rectangular region on a coordinate plane by identifying the coordinates of its vertices and calculating the length and width.
STORY OF HARE AND TORTOISE
The hare and tortoise decide to have a race to a mango tree, with the hare confidently boasting about his speed. However, along the way the hare stops multiple times to eat carrots, radishes, and other vegetables, becoming full and sleepy. While the hare naps, the tortoise steadily plods forward. By the time the hare wakes up and reaches the tree, the tortoise has already arrived, demonstrating that slow and steady wins the race.

Planck’s hypothesis
Planck discovered an empirical formula in 1900 that accurately described blackbody radiation spectra across all wavelengths and temperatures. Seeking a physical explanation, he postulated that the walls of a hot cavity contained identical vibrating oscillators that exchange energy with radiation in quantized units proportional to their frequency, called quanta. This quantum hypothesis explained the experimental observations and values Planck calculated for the universal constant h. While initially a mathematical trick, Planck's quantum theory marked a revolutionary beginning of modern quantum mechanics.
Thesis presentation (proposal)
This study aimed to determine the reading comprehension levels of Bachelor of Secondary Education students at Northern Negros State College of Science and Technology. 33 third year BSEd students participated in the study. They completed a 40 item reading comprehension test adapted from IELTS practice materials. Their profiles were also collected. Mean scores and statistical tests were used to analyze comprehension levels based on profile characteristics and determine if differences existed between groups. The researchers hoped to identify comprehension levels and variables that influence them.
Narcotics
This document outlines policies and procedures for the administration and storage of narcotics. It defines narcotics and describes the assessment that should be done prior to administration including pain scale, vital signs, sedation level and mental status. It provides a sedation scale and states when levels require reporting. It describes safety procedures for administration and reporting conditions. It discusses narcotic storage, counting, documentation and key control. Expired narcotics should be replaced one month prior to expiration. Staff must ensure secure storage and clean areas.
