It was for a: p+r
and b: 0.5(3p+r)

Yes exactly! This exam was pretty easy tbh dont u htink?

This thread might be breaking the rules, but I have to know what was the height of the tip of pyramid from the base area? and what was the angle?

Its not breaing the rules the exam is done!

it WAS VERY EASY I THINK IT WAS 4. SOMETHING actually square root of 20,

The angle wasss 55.7 or somethign liek that i rember found using cos

nah angle was 48.2 and height is root of 20

wat u wrote for set notation??

 

[omar28744]

the side was equal to root 6^2 +4^2 isnt it?
angle was cos inverse the sides isnt it?

 

[crimson]

nah angle was 48.2 and height is root of 20

Yes height was root of 20, then it was a triangle right angle angle 53.54

 

[Nandan Shah]

Yes height was root of 20, then it was a triangle right angle angle 53.54

nah the side was equal to root 6^2 - 4^2 (there has to be subtraction)
and angle was cos inverse of (4/6)
and angle was 48.2 degree

Because base was 4 , hypotenouse was 6

So cos x = 4/6

 

[Nandan Shah]

Yes height was root of 20, then it was a triangle right angle angle 53.54

Because base was 4 , hypotenouse was 6

So cos x = 4/6

then find out the answer.... it is 48.2 and not 53.54

i agree which means teh answer is 48.12 degrees

 

[crimson]

I

i agree which means teh answer is 48.12 degrees

Yes sorry for the confusion, angles need to be given to two decimal palces btw!!!!!!

kk.... wat u wrote for set notation??

then find out the answer.... it is 48.2 and not 53.54

For teh sqequence it was -7n+34 or something like that right?

 

[crimson]

Which question ? on set notation?

 

[Nandan Shah]

For teh sqequence it was -7n+34 or something like that right?

it was -7n+39 and 53rd term

 

[Nandan Shah]

Which question ? on set notation?

in venn diagram: {f,g,h} __ P

 

[crimson]

it was -7n+39 and 53rd term

Yes exactly and the first part of the 6th therm was a negative answer correct?
