# 2.1 Your family and relatives

 Page 1 / 1

## To acquire information from different sources [lo 1.2]

The family you belong to is important to you.

• What is a family?

First we are going to do two exercises on how to use sources on family history. The following will help you to understand family sources.

• Be familiar with all the forms of address of the different members of a family.
• The symbol = means to be married.
• These lines indicate the children of a married couple.

## What is:

• the name of her brother?
• the names of her parents?
• the name of her aunt?
• the name of her sister?
• the names of her grandparents?

## To determine a family’s history with the help of clues [lo 1.2]

These four people are members of the Jantjies family, two brothers and two sisters. You have been a friend of the family for many years.

## Try to establish the history of the jantjies family with the help of certain clues. draw the table below in your exercise book and use the clues that follow to fill in the missing dates.

• Alexander was born in 1898.
• Sophia was born 5 years after Alexander.
• Ben was born 6 years after Sophia.
• Felisia was born 7 years before Ben.
• Felisia got married 30 years after Sophia was born.
• Alexander died 10 years after Felisia got married.
• Ben got married 38 years after Felisia’s birth.
• Sophia was married for 19 years before Ben got married.
• Alexander got married 1 year after Sophia.
• Felisia died 40 years after Ben got married.
• Sophia died 1 year before Felisia died.
• Ben died in the same year as Alexander.

## Assessment

LEARNING OUTCOME 1: HISTORICAL ENQUIRY The learner will be able to use enquiry skills to investigate the past and present.

## Assessment standard

We know this when the learner:

1.3 communicates answers: communicates knowledge and understanding in a variety of ways.

can someone help me with some logarithmic and exponential equations.
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
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
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

hello
Sherica
im all ears I need to learn
Sherica
right! what he said ⤴⤴⤴
Tamia
what is a good calculator for all algebra; would a Casio fx 260 work with all algebra equations? please name the cheapest, thanks.
a perfect square v²+2v+_
kkk nice
algebra 2 Inequalities:If equation 2 = 0 it is an open set?
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

No. 7x -4y is simplified from 4x + (3y + 3x) -7y
is it 3×y ?
J, combine like terms 7x-4y
im not good at math so would this help me
yes
Asali
I'm not good at math so would you help me
Samantha
what is the problem that i will help you to self with?
Asali
how do you translate this in Algebraic Expressions
Need to simplify the expresin. 3/7 (x+y)-1/7 (x-1)=
. After 3 months on a diet, Lisa had lost 12% of her original weight. She lost 21 pounds. What was Lisa's original weight?
what's the easiest and fastest way to the synthesize AgNP?

types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
preparation of nanomaterial
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
what is system testing
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
can nanotechnology change the direction of the face of the world
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.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
how did you get the value of 2000N.What calculations are needed to arrive at it
