Can someone please solve this question?
Thanks a lot !y'= -e^p + e^p(4-p) = y2 - y1/ x2 - x1 ( gradient formula)
= (4-p)e^p - 0/ p - 0
-p^2+4p-4=0
p=2
These questions are from cie m/j 2013 32
USE first differnetiation to find to stationary points the use second drevaite to find which is maximum and minimum.PLZZ help me with this !!!
My guess is a B but it really depends on the grade threshold that year. I calculated 75, so if its a hard year where everybody does badly, you might get an A or a C if the year was easyI hope the same, can u answer my question...
What will my grade be if my score in P12 is 68 and P62 30 ??

which part dont you understand?If its not too much trouble can u explain to me the last question.
How did u devise the vector (1, b,c).which part dont you understand?
y = (1/2)e^2x - 5e^x + 4xPLZZ help me with this !!!
What is this 75My guess is a B but it really depends on the grade threshold that year. I calculated 75, so if its a hard year where everybody does badly, you might get an A or a C if the year was easy
Plane q contains the line AB. Normally to show if a plane contains a line we assume that there are common points on l and plane, in this case point A and B.How did u devise the vector (1, b,c).
Ok i got it. thank you very much. Off the topic though, hows ur prep for maths cuz as i saw your work, damn that was some good stuffPlane q contains the line AB. Normally to show if a plane contains a line we assume that there are common points on l and plane, in this case point A and B.
But they already gave us point A and B so just make use of it. Sorry, I dont really know how to explain it to you.
For math: (68/75)*50= 45.33What is this 75
And arent grade threshold set according to the performances of candidates over the world??
what is low aFor math: (68/75)*50= 45.33
Total= 45.33+30 = 75.33
You can calculate your own total what. And yes grade threshold depends on the whole world. If in the exam you score this mark for a easy exam, the grade will be a B i guess. However, if almost all candidates had a though time, then they will lower the threshold and you might get a low a
Welcome. And yeah progress is painfully slow and torturing.Ok i got it. thank you very much. Off the topic though, hows ur prep for maths cuz as i saw your work, damn that was some good stuff
