La batalla naval de Sinope tuvo lugar el 30 de noviembre de 1853 en el puerto de Sinope, Turquía, entre las flotas rusa y otomana. Rusia buscaba controlar los estrechos entre el Mar Negro y el Mediterráneo, mientras que los otros poderes europeos querían mantener el equilibrio apoyando al Imperio Otomano. En la batalla, la marina rusa destruyó completamente la flota otomana debido a sus nuevas técnicas y tecnología navales, lo que llevó a Francia y
This document discusses checking solutions to quadratic inequalities and graphing quadratic inequalities. It provides examples of checking if an ordered pair is a solution to an inequality and finding the vertex of a quadratic function to graph it as a solid curve below or above the vertex based on whether the inequality is ≤ or ≥.

3.5 solving systems of equations in three variablesmorrobea
This document discusses solving systems of three linear equations in three variables using the elimination method. It provides examples of setting up systems of equations, eliminating a variable to create a system of two equations with two variables, solving the reduced system, back-substituting to find the third variable, and checking that the solution satisfies all three original equations. The solution is written as an ordered triple (x, y, z). Graphing is not recommended due to difficulty accurately graphing three-dimensional planes. Examples are worked through to demonstrate the full elimination method.
This document discusses graphing quadratic functions in vertex and intercept forms. It defines key terms like vertex, axis of symmetry, and parabola. It explains how to graph quadratic functions written in vertex form and intercept form. Examples are provided for graphing functions in each form. The document also discusses how to change between the vertex, intercept, and standard forms of a quadratic equation.
Este documento describe la Batalla Naval de Sinope de 1853. La batalla ocurrió en el puerto de Sinope, Turquía, y resultó en una victoria decisiva de la flota rusa sobre la flota otomana. Las causas de la batalla incluyeron las ambiciones de Rusia por controlar los estrechos entre el Mar Negro y el Mediterráneo, lo que amenazaba la economía de otros países europeos. Durante el combate de aproximadamente una hora, la flota rusa, que había mejorado sus buques con placas de hierro, destruyó
This document discusses quadratic functions in the form of y = ax^2 + bx + c. It explains that a, b, and c are coefficients and the graph will be a parabola with either a maximum or minimum point. Changing the values of a and c affects whether the parabola opens up or down and if it moves above or below the x-axis. Setting a quadratic function equal to 0 allows it to be solved for the x-intercepts, though there may be 0, 1, or 2 solutions depending on the equation. The document presents various examples and explores how changing the coefficients impacts the graph.
Portfolios allow students to collaborate, reflect on their work, and showcase their learning. Google Docs provides tools to develop e-portfolios that foster collaboration through shared documents, comments, and revision histories. Students can include various media like videos, images, and maps to tell the story of their learning. Teachers can use portfolios for formative and summative assessment by having students reflect on artifacts and receiving feedback through comments in Google Docs.
