Measurements on the compass?

More than half of what the line measures. Just take a big measurement that is seemingly a little larger than half of the line.

Switch to Paper 1 June 2004 Q11 if u have pastpaper

Or I have the snap. This is really different from other normal function walaay questions

 

[farhan141]

F:1 -> k means that f(1)=k

F-1:x -> cx + d means that f-1(x)= cx+d

It's easy u have to compare it with the given function.

Well, this type of notation is used in add.maths so it's easy to understand,
(a) k = 1+5/3 = 2
(b) 3x - 5 = cx + d,
So, by comparing,
c=3 , d=-5.

Q.5(b)

Inversely proportional so u dont cross multiply.

8 ---------- 5
X-----------4

and

What do we do in this type of problem? minus the 2 value coming on the cumulative graph?

Q.10 LCM of all 3

140 is LCM so it makes 2h20min. 0900 + 2h20min = 1120

(C) 66-72.

Actually since they asked minutes so answer will be 140 minutes.

Take the lCM, Like of 10 20 and 35 which is 140 (mins). 140/60 = 2 hours and 20 mins. add this to the given value, 0900 + 0220 = 1120.
But since mins are asked, that'd be 140 mins
and

The value at 72 - value at 65
What do we do in this type of problem? minus the 2 value coming on the cumulative graph?

-4,3
-1,-1
-4, -3

 

[passion hunter]

-4,3
-1,-1
-4, -3

can you please explain how did you do it

 

[passion hunter]

-4,3
-1,-1
-4, -3

shouldnt it be (-4,3).....-1,-3, and -4,-3

 

[farhan141]

A. 360-90-90-52=128

C. 128/2 = 64

Reasons?

 

[starship]

can you please explain how did you do it

WAIT SORRY THATS THE WRONG ANSWER!

 

[starship]

shouldnt it be (-4,3).....-1,-3, and -4,-3
