This document discusses evaluating expressions. It provides an example where the variables x, y, and z are assigned numeric values of 2, 4, and 3 respectively.
This math problem involves determining the limit of a function as x approaches 3. Specifically, the function is (x^2 - 8) divided by (x - 3). To solve this, we simplify the function by factorizing the numerator and applying L'Hopital's rule to deal with the indeterminate form 0/0.
1. The document outlines the instructions and questions for a midterm exam in engineering. It contains 3 questions regarding probability distributions, random variables, and statistical testing.
2. The first question involves sampling balls from a box and tracking the number of draws until a specific color is drawn. The second examines the joint probability density function of two random variables.
3. The third question addresses a chemical company's use of a new impurity testing device, including the probabilities of "false positives" and "false negatives". Students are allowed to make reasonable assumptions in their working.
This document discusses numerically solving a differential equation problem to calculate the value function y' = x-y, y(0) = 1 from x = 0 to x = 5 over 50 steps. The analytical solution is provided as 2e−x +x-1 for comparison.
This document provides instruction on solving one-step equations. It defines the addition and multiplication properties of equality, which state that equations maintain their equality when the same operation is applied to both sides. Two examples are given to demonstrate solving equations using inverse operations: (a) subtracting 3/4 from both sides of an equation to isolate the variable x, and (b) dividing both sides of an equation by 16 to isolate the variable f. The general rule for solving one-step equations is explained as identifying the operation on the variable and doing the inverse operation to isolate the variable. Homework practice problems are assigned from the textbook.

Distributive property in algebra power pointkatiewilkerosn
The document discusses the distributive property in algebra. The distributive property allows terms inside parentheses to be distributed so that expressions can be simplified out of order from the standard order of operations. It involves multiplying the number outside of the parentheses by each term inside the parentheses. Examples are provided to demonstrate how to use the distributive property to simplify expressions.
The document provides examples of using the distributive property to break down word problems and number expressions. It shows how to identify a common term or factor in expressions like "firefly + firetruck" and "20 + 30", then use distributive property to write it as the common term distributing over the terms being added or multiplied, like "Fire(fly + truck)" and "10(2 + 3)". Several practice problems are provided to write expressions like "18 + 24" using this method.
Faults form when stresses in the Earth's crust cause rocks to break along fractures. There are three main types of faults: normal faults form when tension pulls rocks apart, reverse faults form when compression squeezes rocks together, and strike-slip faults form when shear forces cause rocks to slide past one another. Most earthquakes occur when built-up stresses are suddenly released as the rocks move along fault surfaces. Earthquake waves travel through the Earth, with P-waves and S-waves causing the ground to shake and damage structures. The resulting shaking can also trigger other hazardous events like tsunamis and liquefaction.
The Earth's crust is divided into tectonic plates that are in constant motion due to convection currents in the upper mantle. There are three types of plate boundaries: divergent where plates move apart and new crust is formed, convergent where plates collide and can cause mountain building, and transform where plates slide past each other. Alfred Wegener first proposed the theory of continental drift in 1912, and the modern theory of plate tectonics explains how plate motions and interactions have shaped Earth's surface over geological time through subduction, volcanism, earthquakes and mountain formation.
The document describes the four main components that make up the Earth system: the atmosphere, hydrosphere, biosphere, and geosphere. It provides details on the composition and key aspects of each component. The atmosphere contains nitrogen and oxygen gases. The hydrosphere contains both saltwater and freshwater. The biosphere includes all living things on Earth. The geosphere is composed of layers within the Earth's crust and mantle.
The document provides 10 multiple choice questions that ask the learner to determine which number has the greatest or least value from a set of decimal numbers. It tests the learner's ability to compare decimal values and identify the greatest and least numbers. An answer key is provided to check the learner's work.

This document provides steps for graphing a function from a function table: 1) Create a function table with input-output pairs, 2) Plot the points on a coordinate plane, 3) Connect the dots to show the linear relationship, 4) Write the function using y=kx notation where k is the constant of proportionality, 5) Describe characteristics of the graph such as if it is increasing, decreasing or staying the same, 6) Extend the graph to find other values of the function.
Bullying can take many forms, including verbal, emotional, physical, cyber, and harassment or sexual harassment. Verbal bullying is the most common and involves name-calling and mocking. Emotional bullying isolates victims or embarrasses them through rumors. Physical bullying hurts people physically or damages their property. Cyber bullying uses electronic means like computers or phones to threaten or humiliate others online or through texts. Harassment challenges people to do things against their will or taunts them about attributes like ethnicity. Sexual harassment directs unwanted gestures, rumors, or touching at a person's identity.
Title IX protects students from harassment and discrimination in schools. It prohibits discrimination based on sex, including sexual harassment. Schools must have a Title IX coordinator to handle harassment complaints and investigate promptly. Students who experience or witness harassment should report it to a teacher, counselor, or administrator so the school can take steps to resolve the situation and ensure student safety.
Wind is caused by differences in air pressure as air moves from high to low pressure. The Coriolis effect causes winds in the northern hemisphere to turn right and left in the southern hemisphere. There are global wind patterns like the trade winds near the equator and westerlies at higher latitudes that help move weather systems. Jet streams are fast winds near the top of the troposphere that also help transport storms and influence flight. Sea and land breezes occur as air moves between bodies of water and land due to differences in how quickly they heat and cool.
There are 6 pencils for every box. The total number of pencils is 240. Write an equation to represent how many boxes there are if there are 6 pencils per box and the total pencils is 240.
This document provides instructions on how to make a foldable to illustrate the five layers of Earth's atmosphere - troposphere, stratosphere, mesosphere, thermosphere, and exosphere. It includes key details about each layer such as its distance from Earth's surface, distinguishing characteristics, and objects found within that layer. Students are directed to additional resources to obtain information to include on their foldable.
Wind is caused by differences in air pressure as warmer air rises and cooler air sinks. The Coriolis effect causes winds in the northern hemisphere to turn right and left in the southern hemisphere. There are global wind patterns like the trade winds and westerlies, as well as jet streams that move storms across countries. Local breezes also form daily over land and sea as each area's temperature changes with the sun.
The document discusses energy transfer in the atmosphere. It notes that the sun provides most of Earth's energy, with about 35% reflected back into space and 65% absorbed. Of the absorbed energy, 15% is absorbed by the atmosphere and 50% by Earth's surface. Heat is transferred through the atmosphere via radiation, conduction, and convection. Radiation transfers energy from the sun, conduction transfers energy through contact between warm and cool objects, and convection transfers heat through circulating air currents. The water cycle is also summarized, where water evaporates from surfaces and transpiration, condenses to form clouds, and falls as precipitation.
The document describes the layers of Earth's atmosphere. It is composed of five main layers - the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere extends up to around 11 km and contains weather phenomena like clouds. The stratosphere extends from 10-50 km above Earth and contains the ozone layer which absorbs harmful UV radiation. The thermosphere is the hottest layer between 85-500 km high, with temperatures reaching 2000 degrees. The atmosphere protects life on Earth by trapping heat and blocking harmful solar rays, but certain gases like CFCs can deplete the ozone layer.
Solving addition and subtraction equations power point copykatiewilkerosn
This document discusses how to solve addition and subtraction equations by using inverse operations. It explains that an equation contains an equal sign connecting two expressions, which may include variables representing unknown numbers. To solve an equation, the same operation must be applied to both sides so that the expressions remain equal. Examples demonstrate finding the value of variables by subtracting or adding to both sides of an equation until the variable is isolated. The key steps are identifying the operation, applying the inverse operation to both sides, writing the value of the variable, and checking the solution.
Identifying parts of algebraic expressionskatiewilkerosn
Algebraic expressions contain variables, constants, and operations. Variables represent unknown quantities and are usually letters like x or y. Constants represent fixed numbers. Operations include addition, subtraction, multiplication, and division, which are shown using symbols like +, -, *, and /.
- 97% of Earth's water is salt water found in oceans and seas, while only 3% is freshwater. Most freshwater is frozen in glaciers and ice sheets near the poles.
- Water cycles between the hydrosphere (oceans, lakes, rivers, atmosphere, and land) through the processes of evaporation, transpiration, condensation, and precipitation. This is known as the water or hydrologic cycle.
- The water cycle involves water evaporating from surfaces, transpiring from plants, condensing in clouds, and falling as precipitation to then collect and flow across the land and into oceans, only to repeat the cycle.
