so......how was it???

Bad! What were the answers to the area question, the one with the circle and the triangle?!?!? And the area for which separate integrations were to be applied?

for the integration..........i got exactly 36....the cubic one

 

[k.k.sibtain]

Didn't you have to add both the areas? Like integrate in separately?

yh...i got 128/3+(-20/3)

 

[k.k.sibtain]

Okay, I didn't get that -_- And what about the area and perimeter of the other question?

 

[Saad96]

I got area to be 128/3 of the integration
Area of garden was 260 something and perimeter was 80.3 I think

 

[DC1313]

yh...i got 128/3+(-20/3)

the second area is not -20/3. it's 20/3. therefore you need to add them --> 128/3 + 20/3

 

[Saad96]

What angles did u guys get for the last cos question?

 

[venecia]

Wht did u get for the trigonometric function ques

 

[venecia]

Wht do u expect the grade boundary to be

 

[cardude456]

how did you guys do the g(Y) part............???

 

[raisul]

some of my answers
area garden - 262.5
perimeter - 80.2
area graph - 148/3
minimum point - 4,-28
a^5/8

I agree but not with the area of graph

 

[Saad96]

The g(Y) was y=1 and y=0.31

 

[Saad96]

Was PT 20?

 

[cardude456]

Was PT 20?

didnt do that part.......how did you do it....??

 

[Alla' Abu-Sultaneh]

what was the length of PT?

 

[Alla' Abu-Sultaneh]

Was PT 20?

I got 20, but i don't know if it's right!

 

[Saad96]

I used Pythagoras for PT and I got 20
