### Grapher

This is a circle centred at 4,4. Because we want the circle to be at +4,+4, we have to -4 from x and y

### Food-for-Thought: What's the Probably of finding the missing plane?

*The following is reported in online Straits Times today (16 March).*

*Click HERE to read the report and to access the dynamic graphic to have a visual sense on the size.*

With the possibility that the MH370 is hijacked, based on the amount of fuel that the missing plane carried with it, the airports that the plane could possibility had landed are identified (in the map shown). According to WNYC, the missing plane could have landed in 634 runways in 26 different countries.

Now, are you able to tell the likelihood, that is, the chances that you will find the plane if you just pick any of these airports? Mathematically, it's possible to have equal chances of finding it in any airport, based on ideal situation. However, the chances of finding the planes in all airport vary now. Why?

### Food-for-Thought: Searching for a needle in a haystack

*The following is reported in online Straits Times today (15 March).*

*Click HERE to read the report and to access the dynamic graphic to have a visual sense on the size.*

MH370 has gone missing for more than 7 days and the relevant authorities have expanded the search area to locating the missing plane. Below is the visual representation to give us a sense of how difficult it is to location an object in a vast area.

Based on the information given in the article, and the 'suggested' size of the search area, are you able to estimate the chance of locating MH370 at the 'defined' search area?

*Hint: You'll need to express your answer in "standard form".*

### Consultation during March Holidays

During the holidays, you may go through the following channels if you need to clarify areas that you are not sure (as you do your homework/ revision):

- Remember to include the question in the email.
- Attempt the question first before you say "do not know how to do". Then take a photo of the working and write down which part you are not sure. Email the photo to me.
- If you do not understand the question, or do not know how to start solving the problem, include the question (either type it or take a photo) and tell me which part of the question you are not sure.
*Note: When sending email, remember to address the email to me; and sign off with your name and class.*- Google Hangout (text)/ Talk
- Face-to-Face session
- I'll be in school from Monday to Thursday; however, will be conducting support programme or running other programmes or attending workshop.
- Therefore, you should make an appointment (at least a day before, via email) with me to ensure that I have time set aside to meet and discuss the work with you.

### Chap 4 (REVISIT): Factorisation... Watch the video...

As you watch the video, look out for the number that the expression was 'factorised'. Apart from identifying and removing the common factor, did you notice that it uses the algebraic identities to help factorise?

Useful identities:

Useful identities:

- (a+b)
^{2}= a^{2}+ 2ab + b^{2} - (a-b)
^{2}= a^{2}- 2ab - b^{2} - (a+b)(a-b)
^{2}= a^{2}- b^{2}

### Chap 4 (PREVIEW): Factorisation by Identifying Common Factors

Listen carefully to the explanation. Two methods are presented.

**Video 3**

### Chap 4 (PREVIEW): Watch the video... Factorisation by Grouping

Factorisation by Grouping: Look out for the approach!

- Taking the terms by pairs first.
- Identify the common factor between the 2 terms first.
- Then carry out the same process - identify the common factor before putting the rest together.
- The video also shows you that the same answer is obtained even if you re-organise the terms (sometimes)

### Revision: Enquiry on Chap 1 - Square Root, Estimation, Word Problem

Here are 3 questions by Jaishree... Just to share with all... might be helpful when you do revision:

**Question 1**

Vishal estimated number as 2000 when he rounded the number to 1,2, or 3 sig figs. Ethan was shocked by Vishal's answer and he asked Vishal what is the smallest and largest possible number such that the estimated number is 2000. Can you help Vishal answer Ethan?

**Question 2**

Evaluate the following without a calculator: Cube root of 0.064 multiplied by 0.6^2- 0.1^3 and the presentation of doing this question

**Question 3**

A class has 30 to 40 students. Each boy has 15 chocolate bars for the party. The chocolate bars are shared equally among 20 girls and the teacher without any leftovers.

a) How many students are there in the class?

b) How many chocolate bars did the teacher receive?
