The document defines geometric sequences as patterns of numbers where each term is determined by multiplying the previous term by a common factor. It provides examples of geometric sequences and explains how to find the geometric mean between two terms of a geometric sequence by setting up a proportion. The geometric mean of two numbers a and b is the number x such that a/x = x/b. It also relates the geometric mean to proportions in a geometric figure with three lengths, where each mean length is the geometric mean of the other two lengths in that proportion.
This document introduces the distance formula, which is used to calculate the distance between two points (x1, y1) and (x2, y2) on a coordinate plane. The distance formula is the square root of (x1 - x2) squared plus (y1 - y2) squared. Several examples are worked through to demonstrate finding the distance between points using their coordinates. Practice problems are also provided for the reader to work through on their own.
The document provides an example of proving that two angles are congruent (<1 ≡ <2) given that two lines (P and Q) are parallel and cut by a transversal (l). It shows the step-by-step work, stating each statement and providing the corresponding postulate or theorem as the reason. It then provides a quiz with two examples to practice applying postulates and theorems to statements about angles and parallel lines.

8.2: Testing a Claim About a Proportion
The document discusses measures of position for ungrouped data including quartiles, deciles, and percentiles. It specifically describes quartiles, which divide a distribution into four equal parts (Q1, Q2, Q3). The Mendenhall and Sincich method is presented for finding quartile values using a formula based on the number of data points. The method involves arranging data in order and determining the quartile positions. Linear interpolation is described for estimating quartile values that fall between data points. An example applies these methods to calculate quartiles for a set of student test scores.

Press Release_BCPS_ School Bank OpeningHoward Rose
Balsall Common Primary School in Coventry has opened its own school bank, run by Year 5 pupils under the supervision of HSBC staff. The school bank was officially opened by Councillor Glenis Slater, Mayor of Solihull, who encouraged the children to learn money management skills and save for the future. Each child that opens an account receives a red safe money box to watch their savings grow. The school thanked HSBC for their support in setting up the bank, which has already motivated younger pupils to start saving.
Economic Disparity in Victorian EnglandLaura Govia
The document summarizes some of the key social changes and domestic policies that occurred in Victorian England. It describes the positive impacts of industrialization, such as increased productivity and economic growth, but also the negative consequences, such as poor working and living conditions for many. Specifically, it discusses the growth of the middle class and factories powered by steam, but also mass enclosure of land, poor public health in urban slums, long work hours in unsafe conditions, and lack of political representation for the working class. Overall, the period saw significant economic changes and disparities between the lives of the wealthy versus the working poor.
CD markers and other markers are used to identify cell types in cancer diagnostics. CD20 is expressed on B-cell lymphocytes and is a target for antibody therapies. CD31 is expressed on endothelial cells and is used along with Collagen IV to identify vascular structures. CD56 is expressed on natural killer cells and some neuroendocrine tumors. P63 is commonly expressed in squamous cell carcinomas and transitional cell carcinomas but not adenocarcinomas. HER2 is overexpressed in some breast and gastric cancers and is a target for Trastuzumab therapies. Vimentin is expressed in mesenchymal cells and tissues and increased expression has been reported in various epithelial cancers.
The document discusses energy efficiency upgrades that can be made to heritage buildings in Vancouver. It provides details on Vancouver's goals to reduce energy consumption in homes by 33% by 2020. It then lists 12 ways to make a house more energy efficient, such as efficient lighting, insulation, and water heating. The document also discusses the benefits of upgrading heritage buildings, which include embodied energy retention and reducing thermal bridging. It provides a case study of Vancouver's efforts through its 2020 Greenest City Action Plan to address energy usage in the city's large number of heritage buildings.

Znazorneni sily
1. Znázornění síly
(Učebnice strana 35 – 36)
Chlapec kope do míče.
Čím větší silou do míče kopne, tím dále poletí.
Účinky síly závisí na její velikosti.
Míč poletí tím směrem, kam ho chlapec kopne.
Účinky síly závisí také na směru síly.
Chlapci se houpou na houpačce.
Druhý chlapec
působí stejnou
silou, ale vždy
v jiném místě.
1.
2.
3.
Účinky síly závisí i na místě, kde síla na těleso působí.
Toto místo budeme nazývat působiště síly.
2. Síla je určena velikostí a směrem. Její účinek závisí i na poloze
jejího působiště (místě, v němž síla působí). Sílu znázorňujeme
šipkou (orientovanou úsečkou). Počátek odpovídá působišti síly, délka
šipky udává velikost síly, směr šipky udává směr síly.
P ... působiště síly
velikost síly odpovídá délce úsečky
P
směr síly odpovídá orientaci úsečky
Grafické znázornění síly: F = 4 N
nakreslíme přímku, v jejímž směru síla působí
označíme působiště síly P
^
zvolíme vhodné měřítko (např. 1 cm = 1 N)
naneseme velikosti síly (od působiště)
(Pro snazší určení velikosti síly vyznačujeme
někdy na úsečce dílky)
zakončíme šipkou a označíme
P
F
3. Grafické znázornění síly:
^
měřítko 1 cm = 1 N
F1 = 8 N, působí vodorovně zleva doprava
F1
F2 = 3 N, působí svisle
shora dolů
F2
F3 = 6 N, působí šikmo doleva
zdola nahoru
F3
^
F4 = 270 N, působí vodorovně zleva doprava, 1 cm = 30 N
F4
^
F5 = 0,7 N, působí vodorovně zprava doleva, 1 cm = 0,1 N
F5
4. Všechny obrázky představují stejnou sílu F = 12 N
Stejný obrázek může představovat pokaždé jinak velkou sílu
(podle toho, jaké si zvolíme měřítko).
F1 = 10 N
(10 · 1 = 10)
F2 = 0,5 N
(10 · 0,05 = 0,5)
F3 = 1000 N
(10 · 100 = 1000)
F4 = 250 N
(10 · 25 = 250)
5. Při zvedání kbelíku působíme silou F svisle vzhůru.
F
Zavěsíme-li kbelík na provázek,
budeme jej zvedat stejnou
velkou silou F, stejným směrem,
ale působiště síly se posune
po provázku směrem vzhůru.
F
Působiště síly můžeme
posouvat po přímce ve směru
pohybu, pohybové účinky síly
na těleso se přitom nemění.
Posuvný účinek síly na pevné těleso se nezmění,
posuneme-li její působiště do jiného bodu tělesa po
přímce, ve které síla působí.
Tento poznatek budeme často využívat při znázorňování
sil, zejména když budeme znázorňovat dvě a více sil
působících na totéž těleso.
