Ch 7 Exponential growth-REFRESH 

In this lesson ...

We will do a bit from Refresh p.8/9 together.

After this you will make the other exercises yourself.

Now all do this:

+ Take a new page in your Notebook

+ Write down 'Ch 7 Exponential growth' on top of it

+ Make a marginline -using a ruler!- if you don't have one yet

+ Write 'R1' in the margin 

+ Make R1a now, in your Notebook!

Make 1a in your Notebook.

Send in your answer in the next slide.

Answer to R1a:

Now copy the Ratio Table fromR1b and fill it in

(you may also fill it in in your Flexbook):

Here is the answer.

Watch how handy the number '1' is used!

Now try R1c.

Use the same table, with '1' on top:

1c  A lamp post is 3.5 metres tall. Make a ratio table and  calculate     the                     length of the shadow of the lamp post.

       You MAY use the same ratio table:

And now...

Time for doing the Homework:

REFRESH: R2 until R7

For R4 and R5 MAKE A RATIO TABLE every time! Like we just did.

For every exercise give your CALCULATION!
