3.1 'n studie van grafieke (Page 2/4)

Wiskunde graad 9

Page 2 / 4

Steilte (of helling) word bereken deur die vertikale afstand deur die horisontale afstand te deel, so: $\frac{vertikale verandering}{horisontale verandering}$ . Dit is presies hoe ons later die gradiënt van ’n grafiek gaan bereken.

3.1 Wat is die hoogte bo seespieël van die posisie wat presies halfpad tussen die twee heuwels is?

3.2 Wat is die verskil in hoogte van die twee heuwels?

3.3 Wat is die laagste plek, volgens die grafiek?

4 Soek self grafieke om uit te pluis. Jy sal grafieke kry in koerante, tydskrifte (motor-, sport- en finansiële tydskrifte) en handboeke van ander vakke. As jy ’n atlas het, is dit ’n goeie plek om interessante grafieke te kry. Indien moontlik, bring hierdie grafieke skool toe vir bespreking. As jy belangstel in die onderwerp van die grafiek, kan jy jouself vrae vra soos dié hierbo.

In die module oor statistiek sal jy leer van meer en ander grafieke.

Sitplekke in die skoolsaal:

Die diagram stel ’n skoolsaaltjie voor. Die blokkies is sitplekke vir die gehoor. Daar is drie deure (Х) – een agter en twee in die middel van die kante. Vanaf die verhoog is die Linkerhelfte en Regterhelfte van die stoele sigbaar aan weerskante van die paadjie. Die ander paadjie skei die voorste stoele (met Sagte sitplekke) van die agterste stoele (met Harde sitplekke).

Die rye word van die middel van die saal van 1 tot 6 vorentoe, en van 1 tot 6 agtertoe genommer, en van 1 tot 6 regs en van 1 tot 6 links, soos van die verhoog gesien.

Die vier kaartjies vir die sitplekke met die wit blokkies het nommers: L4S1, L5H4, R2S2 en R4H2. Soos jy kan aflei, sê die eerste letter of die sitplek links of regs is; die nommer daarna sê hoe ver die sitplek vanaf die middelste paadjie is. Die volgende letter sê of dit ’n sagte sitplek (voor) is, of ’n harde sitplek (agter), en die laaste nommer sê hoe ver die plek van die dwarspaadjie af is.

1.1 Vir hoeveel mense is daar plek in die saal?

1.2 As jy moet plekke aanwys, moet jy weet watter wit blokkie hoort by watter kaartjie. Vul die korrekte nommer by elke wit blokkie in.

1.3 Soek op die diagram en vul in waar die volgende stoele is: R6S6; R5H1; L1S1; L6S1; L2S5; L3H3; R1H1.

1.4 As daar 25 ekstra stoele in die saal moet kom, kan hulle in die paadjies gesit word. Hoe sou jy die nuwes nommer sonder om die bestaande nommers te verander? Kan die letters nog gebruik word? Wat van die nommers?

2. Nommering van punte op grafiekpapier:

Hierdie diagram wys die Cartesiese vlak .

Die getalle is van toepassing op die lyne en NIE die spasies tussen die lyne nie.

Die donker horisontale lyn noem ons die х–as en die donker vertikale lyn is die y–as. Die plek waar die asse mekaar kruis word die oorsprong genoem. Die koördinate van die oorsprong is (0 ; 0). Koördinate word altyd geskryf as twee getalle geskei deur ’n kommapunt, in hakies.

explain how nature and nurture affect the development and later the productivity of an individual.

Amesalu Reply

nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities. before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

Jharna

continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child

Jharna

child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective

Jharna

results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
