  • Integration of Themes: Friends
  • Inclusively: Although we are all unique, we share many similarities; appearance, sport, education etc.
  • Social Justice: Friends and their expected behaviour towards one another.
  • A healthy environment: This is our responsibility – what can we do about keeping our environment healthy?

Educator’s page

  • Each learner has page 7.
  • "Why do we want a calendar?" [ It tells us the days of the week, months of the year and the date. This is important so that we can know when our appointments are, when our birthdays are, which days are school days, which weekends, etc.]
  • What is the first day of the week? Sunday.
  • Let's say all the days of the week beginning from Sunday.
  • Questions: - Which day comes after e.g. Monday? After Friday, etc?- Which day comes before e.g. Wednesday? Before Sunday, etc?- Which day comes between Tuesday and Thursday, etc?- At which month of the year are we looking now?- How many days in January?- Count to 31 forward and backward.- On which day is the 3rd of January? How do you know? On which day is the 10th of January?- How many days from the second of January to the tenth?- What day is it today? Today is ......................... . Tomorrow will be ......................... . Yesterday was ......................... . - What is today's date?- When did school begin?- Count all the school days in January.- Which month comes after January?- Learn the song: January, February, March, April...- Read and do the instructions on page 7.

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
🤔.

I rally confuse this number And equations too I need exactly help

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

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

Hello

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?
