My Exam 1 answers

-7 - k, is right, they didnt say find k, so im sure -7 -k is correct aswell

Hopefully. Im so fucking stupid, fuck.

Question 1


Question 2
a) 390N

Question 4


Question 10
a)


b)

Ferk well I got all those incorrect (missing two answers in one, should at least get one mark for methods, got a negative in question 2 instead of positive 390, no idea what I did wrong with q4 but I know I got it wrong and q10 I just subbed the limits in instead of solving inequalities and q10b I got b=-1/4, a=1, c=1)

By the way for Question 10b my calculator is telling me instead of

I think I said that to myself as well :[

They said Hence evaluate the gradient of the curve at the point (1,1), they didn't say Evaluate the gradient of the curve at (1,1) in terms of k

for the reaction force questions, i accidently wrote 9.8x50=4800. how many marks will i lose for both q's seeing as my working is correct?

I think you should just lose the answer mark so 2/4 then? Dunno, that is what I am assuming

You're not alone buddy !!   - such a simple thing we all missed =.="

how many marks was 5c worth, they one where we have to get dy/dx?

if u left it as -7-k, how many marks would you get?

from memory i think it was a 2 mark question

[homghomg1]

-7 - k, is right, they didnt say find k, so im sure -7 -k is correct aswell

considering they said evaluate the gradient, and not evaluate the gradient in terms of k, it was implied you had to work out k

I'm thinking since it was a 2 mark question, the marking scheme could be 1 mark for correct method (solving for k AND subbing in values of x, y and k into dy/dx) and 1 mark for answer (-6)

therefore all those of us who just left it as -7 -k could get 0 marks for that question :/
i hope not

FUCK FUCK FCK KUNT FUCK FK!!!! damn that k question
lolllll

damn, thanks for ruining my night

Wouldn't it be 1 mark for finding the gradient and 1 mark for subbing in k?

I just checked with my calculator and I got what I put in above.

The original function was

[BlueYoHo]

omg Q10b) it said integer didn't it?
SHIIIIIIIIIIIIIIIT
a fraction is not an integer isn't it??? *************

u guys think thats only minus 1 mark if i left it in fraction form? ****!!!!!!!!1
