The document discusses safe digital social networking and poses a series of questions about privacy, security, and age-appropriate interactions on social media sites like MySpace and Bebo. It asks whether profiles are fully protected, if users have experienced stalking, if parents want their kids' accounts deleted, if these sites are safe for young kids, and if communication with unknown age groups or lack of oversight makes the sites safe for children.
Uniform circular motion describes an object moving at a constant speed in a circular path, caused by a force directed towards the center called the centripetal force. While velocity is always tangent to the circle, acceleration and centripetal force are always pointed towards the center, meaning the object is constantly accelerating even if its speed does not change. The equation for centripetal force is Fc=(m)(ac), where Fc is centripetal force, m is mass, and ac is centripetal acceleration.
Uniform circular motion (UCM) describes the motion of an object that moves at a constant speed along a circular path. While the object's speed remains constant, its direction of motion continuously changes. For UCM to occur, the net force on the object must be directed toward the center of the circle and be large enough to cause centripetal acceleration, which changes the direction of motion but not the speed. Key formulas define centripetal force, speed, and acceleration for objects in UCM.
La Unión Europea ha anunciado nuevas sanciones contra Rusia por su invasión de Ucrania. Las sanciones incluyen prohibiciones de viaje y congelamiento de activos para más funcionarios rusos, así como restricciones a las importaciones de productos rusos de acero y tecnología. Los líderes de la UE esperan que estas medidas adicionales aumenten la presión económica sobre Rusia y la disuadan de continuar su guerra contra Ucrania.
The document compares exponential and linear models. Exponential models exhibit constant percentage change determined by the growth factor b, while linear models show constant increase/decrease set by the slope m. Exponential equations can be determined from a single point, unlike linear equations which require two points to find the parameters m and b. The document demonstrates finding the exponential equation for two given points (2,6) and (4,10) by setting up equations and dividing them to isolate the growth factor b.

This document summarizes the key factors that led the United States to initially remain neutral in World War I but eventually enter the war in 1917. It discusses the economic reasons for neutrality due to American loans to the Allies and not wanting to jeopardize being repaid. It also describes the human toll of the war and desire to avoid U.S. casualties. However, events like the sinking of the Lusitania, which killed American citizens, and the Zimmerman Telegram proposing a German alliance with Mexico against the U.S. increased pro-war sentiment and helped push the U.S. into the conflict.
Early social networks like BBS and Usenet allowed users to connect and share messages and files. Classmates.com helped connect old friends and classmates by allowing them to post photos and read message boards. Modern social networks like MySpace, Facebook, Flickr, and LinkedIn allow users to share photos, videos, updates, and connect with others. These networks have evolved to be accessed on mobile phones, and will likely continue changing as new platforms emerge.
Uniform circular motion (UCM) describes the motion of an object moving at a constant speed in a circular path. Centripetal force is directed towards the center of curvature and causes the object to travel in a circular path. During UCM, centripetal force and centripetal acceleration are directed towards the center, while the velocity is tangential to the path. Examples show that the centripetal force can be the force of friction, normal force, tension, or gravity depending on the situation.

Pascal's Triangle is an array of numbers arranged in triangular form where each number is derived from adding the two numbers directly above it. To generate the triangle, a chart is made where the terms are found by taking the binomial coefficients of n over r, and properties include that each row has one more term than the previous row and the first and last terms of each row are always 1.
This document discusses using linear models to summarize relationships in data. It provides examples of how astronomers use a linear model called Hubble's Constant to describe the relationship between galaxies' distances and velocities. It introduces the correlation coefficient r as a measure of how closely data points fit a linear model or line of best fit, with r values closer to 1 or -1 indicating a stronger linear correlation. Some scatter plots with r values are shown to illustrate what different r values look like. The document explains the formula for calculating r and encourages interpreting what the various parts of the formula represent. It then poses fitting a line of best fit to a set of sample x and y data values as an example.
This power point is intended to help students make their own lexicons by paying attention to the language around them. It was inspired by Michael McCarthy and Felicity o'Dell's English Vocabulary in Use, CUP.
As developers, we put a lot of effort into keeping our code clean, clear, and flexible. So why do we let our CSS become such a mess? It's time to grow up as web developers and take responsibility for writing high-quality CSS and keeping it that way. Here's how I did it on a recent project.
The document discusses functions and function notation. It defines a function as a special type of relation where each element of the independent variable is paired with exactly one element of the dependent variable. It provides examples of different ways to represent functions, including coordinate graphs, symbolic rules, and ordered pairs. The document also discusses evaluating functions, the domain and range of functions, and identifies whether certain relations are functions or not.
This document provides 5 calculus limits to evaluate: 1) as x approaches 0, 2) as x approaches infinity, 3) as x approaches -1, 4) as x approaches 0, and 5) as x approaches infinity.
This document discusses expanding the concept of limits to include infinite limits, where the variable approaches infinity. It introduces the idea of analyzing functions where the variable gets infinitely large and the limit potentially reaches infinity as well. The example function raises the question of how to analyze its behavior as the variable increases without bound.
This document discusses continuity and discontinuity in functions. It defines a function as continuous at a point c if the left and right hand limits are the same as x approaches c. A function is discontinuous if the left and right limits do not match up. Examples are given of different types of discontinuities like removable discontinuities.

Variance and standard deviation are measures of spread used to describe the shape of distributions associated with the mean. While two distributions may have the same mean, their variance and standard deviation can show that they have very different shapes. To calculate variance and standard deviation, you first find the deviation of each value from the mean, square the deviations, and sum them. You then divide the sum by n-1 to get the variance, and take the square root of the variance to find the standard deviation.
The document discusses the concept of limits in calculus, including the formal definition of a limit as the value a function approaches as the input gets arbitrarily close to a given number. It provides examples of evaluating limits graphically and algebraically, such as determining the limit of a function as x approaches 3 is 6, even though the function is undefined at x=3 due to a removable discontinuity. The document also discusses using graphs to identify different types of discontinuities and limits.
The document discusses using the trapezoidal rule to evaluate definite integrals by approximating the area under a curve between bounds with trapezoids. It explains that the trapezoidal rule is a more exact method than counting squares. To use the rule, the integral bounds are divided into trapezoids, the function is evaluated at the endpoints, and the areas are calculated by multiplying the average base by the height and summing the results, with endpoints weighted by one half.
The document discusses the five number summary, which includes the minimum, first quartile, median, third quartile, and maximum values. It provides an example of the heights of a basketball team, calculates their five number summary and interquartile range, and discusses how outliers can be identified using 1.5 times the interquartile range.
The document discusses using integrals to calculate distance traveled based on a velocity-time graph. It explains that the area under the graph between two times represents the distance traveled during that interval. Specifically, it asks the reader to:
1) Find the velocity between 30-50 seconds from the given graph and explain why the distance can be found from the rectangular area.
2) Count the squares and find the distance traveled from 0-20 seconds by finding the area under the curved graph.
3) Estimate the definite integral of a function representing a football's cross-sectional area to find its total volume.
The document discusses different measures of central tendency, including the mean and median. It introduces the concept of using sigma notation to simplify writing out long sums, such as when calculating the mean of a data set. It provides an example of entree prices from a restaurant and encourages writing out the formula to calculate the mean using sigma notation.
This document discusses functions, their derivatives, and rates of change. It introduces the concept of the derivative as the instantaneous rate of change of a function. It then asks the reader to sketch and describe different types of functions without a calculator. It provides a sample graph showing sections that are increasing, decreasing, or neither, and asks the reader to identify these sections and determine where the rate of change is more or less quick.
A stemplot is a method to display data by splitting each number into a stem and leaf, with the ones digit as the leaf and other digits as the stem. It allows comparison of two data sets side by side. A dotplot displays the frequency of data values and is useful when the data is categorical. It may not be suitable to display continuous numeric data like golf scores.
Factoring by grouping allows factoring out the greatest common factor from some but not all terms of a polynomial, which can make the entire factorization easier. This technique can be used to factor difficult quadratic trinomials. Examples are provided to illustrate factoring by grouping.
The fundamental theorem of algebra states that any polynomial of degree greater than 1 with complex coefficients has at least one complex zero. A related theorem is that a polynomial of degree n has at most n zeros. Another theorem is that a polynomial of degree greater than 1 with complex coefficients has exactly n complex zeros counting multiplicities.
The document discusses finding polynomial models to describe patterns like triangular numbers and tetrahedral numbers. It explains that a polynomial difference theorem can be used to find the polynomial formula for functions where the differences between successive values form a known pattern. Specifically, if the fourth differences are constant, the function is a fourth degree polynomial that can be determined by plugging known points into the general cubic polynomial formula.
The document discusses polynomial models and volume equations. It provides an example of a box made from cardboard where squares are cut from the corners and the sides are folded up. An equation is written for the volume of the box in terms of x, which is a third degree polynomial. A polynomial's degree is the maximum number of variables being multiplied. The standard form of a polynomial of degree n is also discussed. The volume of the cardboard box is written in standard form. A polynomial with more than one variable, like (x+y)^4, has a degree of 4.
This document discusses key concepts related to graphs of polynomial functions, including:
- Extrema (maximum, minimum, relative maximum, relative minimum points) and where they occur on the sample graph
- Zeros (x-intercepts) and that the sample function has four zeros
- Increasing and decreasing intervals based on the slope, with the function increasing where driving uphill and decreasing where driving downhill
- Positive and negative intervals, referring to where the function is positive or negative based on the y-value.
The document discusses binomial probabilities and permutations for repeated independent trials with two possible outcomes. It asks what the probability is of getting 4 or more blues when spinning a spinner 6 times, and the probability of getting 3 or more reds in 6 spins. It introduces the binomial probability theorem for calculating these probabilities.
Pascal's Triangle is an array of numbers arranged in triangular form where each number is derived from adding the two numbers directly above it. To generate the triangle, a chart is made where the terms are found by taking the binomial coefficients of n over r, and properties include that each row has one more term than the previous row and the first and last terms of each row are always 1.
Combinations involve selecting objects without regard to order. A combination counts arrangements like AB and BA as the same, unlike permutations. The number of combinations is represented by nCr, which is fewer than the number of permutations nPr since order does not matter in combinations. This document provides examples of counting combinations of letters, line segments between points on a circle, and the probability of neither yourself nor a friend being selected from a class for an interview.
