I need help in question 19 in may/june 10 v 21
I didn't get the question

so first part u r just supposed to sub in values in for t. For t=3: r= 2p + 3(p+q) r= 2p + 3p + 3q r= 5p + 3q

Now, for the second part, it shows 1p = 2 boxes on x-axis AND 1q = 2 boxes on y-axis.
one by one sub in each point. for example for t=3 , r= 5p + 3q. this means go 10 boxes on x-axis and then from there start moving up 6 boxes. wherever u get mark that point. Follow for the same for the rest.

V23 o/n 12 q16 and 17 and 18 help please

 

[Kuukua]

Could i please get help on how to draw stretched diagrams?

 

[ahmadumar]

Could i please get help on how to draw stretched diagrams?

so if the question says stretch by a factor of 3 along the x-axis, all points along x-axis will be multiplied by 3. Now, take the example of a rectangle. If u r supposed to stretch by factor of 2 along x-axis. All the x-coordinates will be multiplied by 2.

Sure will

I guess its right.... thanks for the help anyways!

 

[ahmadumar]

lol i hope its right no problemo

 

[Nandan Venkatesan]

lol i hope its right no problemo

Now that just got me thinking........ I think its not right because what about the length below the sphere?? The gap between the sphere, the wall and the floor?? That tiny gap too will have a length right?? What do you think??
