Math school-books-3rd-preparatory-2nd-term-khawagah-2019
This document is the introduction to a mathematics textbook for third preparatory year students. It discusses the book's organization and goals. The book is divided into units with lessons, exercises, and tests. It aims to make mathematics enjoyable and practical, helping students understand its importance and appreciate mathematicians. Color images and examples are used to illustrate concepts simply and excitingly to facilitate learning.
Deriving the quadratic formula
The document derives the quadratic formula step-by-step: [1] It begins with the standard quadratic equation ax2 + bx + c = 0 and transforms it through steps such as completing the square and applying the square root property, [2] This results in the familiar quadratic formula of x = (-b ± √(b2 - 4ac)) / 2a, which gives the solutions to any quadratic equation.
10.5 more on language of functions x
The document discusses notation and algebra of functions. It defines a function as a procedure that assigns a unique output to each valid input. Most mathematical functions are represented by formulas like f(x) = x^2 - 2x + 3, where f(x) is the name of the function, x is the input variable, and the formula defines the relationship between input and output. New functions can be formed using basic operations like addition, subtraction, multiplication, and division of existing functions. Examples are provided to demonstrate evaluating functions at given inputs and combining functions algebraically.

Simultaneous equations (2)
The document discusses solving systems of 3 linear equations with 3 unknowns. It provides examples of using the elimination method, which involves rewriting the system as two smaller systems, eliminating the same variable from each, solving the resulting system of 2 equations for the remaining 2 variables, then substituting back into one of the original equations to find the third variable. The solution is written as an ordered triple (x, y, z). It demonstrates this process on examples and encourages practicing this method.
Graphing quadratic equations
1) This document discusses how to solve quadratic equations by graphing, including identifying the terms of a quadratic equation, finding the solutions by graphing, and graphing quadratic functions.
2) The key steps for graphing a quadratic function are to find the axis of symmetry using the standard form equation, find the vertex point, and find two other points to reflect across the axis of symmetry to complete the parabolic graph.
3) An example problem walks through graphing the quadratic equation y = x^2 - 4x by first finding the roots, vertex, and axis of symmetry, and then constructing a table to plot points and graph the parabola.

Quadratic And Roots
This document discusses quadratic equations and their properties. It defines quadratic equations as equations of the form y=ax^2 +bx + c, where the highest power is 2. It explains that quadratic equations can be solved using the quadratic formula, x = -b ± √(b^2 - 4ac) / 2a. The number of solutions depends on the discriminant, b^2 - 4ac. If it is greater than 0, there are two solutions, if equal to 0 there is one solution, and if less than 0 there are no solutions. Examples are provided to demonstrate solving quadratic equations.

trp Operon - Virtual High School (VHS) - SBI4U
trp Operon
Recall
Cells respond to their environments by modifying gene expression.
Prokaryotic cells can individually adapt to their changing environments by
regulating the expression of their genes.
Bacteria can adjust to their environments using a special sequence of DNA
known as an operon, which controls the synthesis of protein in response to the environment. An operon has three key areas on the DNA strand: the promoter, the operator, and the transcription unit. The bacteria Escherichia coli need the amino acid tryptophan to survive. Amazingly, if tryptophan is not readily available in its environment, E. coli will actually make its own tryptophan from another compound by activating a metabolic pathway called the trp operon (trp for tryptophan). This metabolic process “shuts off’ as soon as tryptophan is readily available again. How the trp Operon Works Tryptophan is made using a sequence of five different enzymatic reactions. The genes that code for these five enzymes are clustered together on the same chromosome. A single promoter transcribes the entire cluster at once. In this way, the cell can turn “off” or “on” the entire series of functionally associated genes simultaneously. Let’s look at the molecules that cause these switches to be “on” or “off”. 1. How does gene regulation involving the trp repressor protein differ from what you observed with the lac repressor in the previous lesson? (2 points) 2. Based on your understanding of gene regulation in the cell and the function of the trp operon, describe how this process would be affected if there was a mutation in the operator region so that the operator could not carry out its function. (4 points) 3. What would be the result in this process of a genetic mutation that altered the shape of the trp repressor protein? (4 points)

A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
