Ch 5 SUMMARY p.188-191

This paragraph contains:

+ all the important 'Theories' and 'Skills' 

+ USE the methods they show you in the 'Skills'!

+ for every subject a few exercises are done by you

+ so it is great stuff to learn and practise !

Get ready!

1. Open your Notebook

2. Get your pen, pencil and geo 

a short trip to §5.6 first:

Exercise 40 is a practical application (toepassing) of

+ quadratic formulas 

+ tables, and

+ graphs 

+ awesome, indeed!

+ with or without socks

Calculate it on paper

In the PHOTOVRAAG, next slide,

send in a picture of your 

CALCULATION!

A TIP: When all the vitamin has gone, what value will

p be, then?

p=100−4t​2​​

Hi all, here's my CALCULATION:

Calculate the outcomes for t = 3 and t = 4 only, now.

Do this on PAPER.

Key in in the next slide.

p=100−4t​2​​

My 2 answers are:

p=100−4t​2​​

What kinda shape of graph will come from the table?

1. a straight line
2. half a horizontal line
3. half a parabola
4. a parabola

Discuss with your neighbour what could be a good scale for the vertical axis.

So: how many days (t) into 1 cm?

Then key it in the next slide. One answer for every pair is enough.

p=100−4t​2​​

Our scale is ..... in 1 cm.

Key in your answer in the next slide.

After ..... days.

1. 50
2. 4
3. 3
4. 3.5

The formula is: 

The number of days is 3.5   

You may use your calculator.

Especially for squaring 3.5 !

p=100−4p​2​​

Now it's time to make the SUMMARY (p.188-191)!

Do this as follows:

1st Study the Theory or Skill

2nd Make the Exercise that follows

3rd Repeat this all the time until you've finished S6.

4th Correct your work with the Solutionsbook

5th Take a few pics and

6th Send'm in in GC

Homework is fun, but free time too...

Homework time

Consider this:

+ Homework may be one of the blessings in life, but

+ Make sure you don't have too much of it, by
