Aktiwiteit: afstand [lu 1.8, lu 3.2, lu 3.6, lu 5.5]

Bonnie en Tommie is baie opgewonde, want hulle gaan elke Desembervakansie see toe.

  • Teken jou eie strandtoneel. Ek wil sien hoe dit daar lyk en wat jy alles daar doen.

Verlede jaar was Bonnie en Tommie saam met Pappa en Mamma Durban toe. Hierdie jaar gaan hulle Kaapstad toe. Hulle woon in Kimberley.

  • Kyk of jy hierdie stede op die kaart kan kry en merk dit.
  • Merk ook die omgewing waar jy woon en skryf die dorp of stad se naam in op die kaart.
  • Is dit naby of ver van Kimberley af?

Dit is __________________________.

  • Trek die roete wat Bonnie-hulle van Kimberley tot by Kaapstad gaan ry duidelik met jou potlood op die kaart in.
  • Skryf neer al die name van die dorpe langs die roete wat jy gekies het.

Kimberley ____________________________________________________

____________________________________________________ Kaapstad

  • Hoe ver skat jy is Kimberley van Kaapstad af?

Ek skat dit is _____ km.

  • Gebruik die afstandstabel op bladsy 4 en lees af wat die afstand is.

Dit is _____ km.

  • Het jy te veel, te min of net reg geskat. Ek het__________________.
  • Kyk weer na die kaart en skat:

Is Durban nader of verder as Kaapstad van Kimberley af?

Ek skat _______________.

  • Lees die afstand van die tabel af. Dit is _______________ km.
  • Bepaal nou die verskil tussen die twee afstande.

Die republiek van suid-afrika

  • Hierdie is 'n kilometerafstandstabel of -rooster wat die benaderde afstande tussen 2 dorpe of stede aandui.

  • Die afstand tussen Kimberley en Durban is op die rooster ingekleur as voorbeeld. Die 2 stede is 825 km van mekaar.
  • Kies 'n maat en oefen 'n paar aflesings.

Die afstand tussen Kaapstad en Johannesburg is 1 421 km.

Gebruik weer die kaart om eers die afstande te skat en dan op die rooster op bladsy 4 af te lees. Doen dit saam met 'n maat.

  • Bepaal die som van die afstand tussen Bloemfontein en Beaufort-Wes en die afstand tussen Port Elizabeth en George.
  • Ons woon in Pretoria en Pappa werk in Johannesburg. Hoeveel km ry Pappa op 'n dag?
  • Hoeveel km ry hy in 5 dae?
  • Dit het 5 uur geneem om die afstand tussen Kimberley en Beaufort-Wes af te lê. Hoeveel km het ons in 1 uur afgelê?

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder gepaste simbole in berekeninge gebruik om probleme op te los;

Leeruitkomste 3: Die leerder is in staat om eienskappe van en verwantskappe tussen tweedimensionele vorms en driedimensionele voorwerpe in 'n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.2: Dit is duidelik wanneer die leerder tweedimensionele vorms en driedimensionele voorwerpe in prente en in die omgewing beskryf, sorteer en vergelyk;

Assesseringstandaard 3.6: Dit is duidelik wanneer die leerder informele kaarte van die skoolomgewing of van ’n groep driedimensionele voorwerpe lees, interpreteer en teken en dui die voorwerpe op die kaart aan;

Leeruitkomste 5: Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak en om toevallige variasie te interpreteer en te bepaal.

Assesseringstandaard 5.5: Dit is duidelik wanneer die leerder data lees en interpreteer wat in eenvoudige tabelle en lyste voorgestel word.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi
🤔.

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
