when they say to shade the region inthe loci questions ....does the locus have to be a dotted line ??or does it depend on the inequality like when the question says more than and less than and only thn we will draw it dotted...

No, doesn't need to be dotted.

 

[funky brat]

did you get it right the first time?

I got it right the first time. Can I get an A?

 

[exploded diper]

No, doesn't need to be dotted.

all lines dont need to be dotted ...not even the ones which are indicating a region or a point more or less than sumthing......i am confused...

Which question?

 

[exploded diper]

I'm getting 7.75 but not 7.5

ohhh so u guys wer talking bout tht question...i thought the one bout the speed one...this question was more easier ........thn tht one....

 

[exploded diper]

Which question?

normal question in which it says draw the locus of points 5cm more than a and stuff etc...........

 

[funky brat]

Strictly inside. They bold the word inside. In Rxaminer Eeport they say cansidates should ppen their eyes wide and read the question carefully.

You mean the extra lines and the part of the circle not the region asked must be erased?

What? But aren't the construction arcs always outside the triangle/region?
We don't have to join the arcs fully? Only in that region?

How to do this?
The L.C.M of 6,15 and x is 90. find two possible values of x which are odd numbers

√4√4√4....vats the ans of this...in this question the first under root is above the other two and the second under root is above the last one......if u get it thn ans this......

The L.C.M of 6,15 and x is 90. find two possible values of x which are odd numbers

6 = 2 * 3
15 = 3 * 5

x = ?

90 = 2 * 3 * 3 * 5

Now, either x can be 3*3, or 3*3*5

So, 9 or 45?

The L.C.M of 6,15 and x is 90. find two possible values of x which are odd numbers

lcm of 6 and 15 is 30
x has an extra 3
so it could be 15x3=45
or 3x3 =9

Yes as it would be locus of points outside quadilateral/figure/etc

What? But aren't the construction arcs always outside the triangle/region?
We don't have to join the arcs fully? Only in that region?

Arcs are to aid you in drawing the locus and they are not part of the locus so they need not be erased but anything part of the locus and not within the boundary should be erased.

Is it important to state the property in a one mark question for angle circle properties ?

 

[princess Anu]

How to describe a locus ? :s

Q-10 (a)
Could someone solve it for me? =c

Total = 3+5 = 8

Jane - 5
Ken - 3

Difference of 2 parts so that is equal to 16$. 1 part then is equal to 8$
Total sum = 8 x 8 =64$

Hissa of Jane = 5/8 x 64 = 40
Hissa of Ken = 3/8 x 64 = 24

Easy shit. .-.

Q-24 from the same paper? Am I asking for too much?
