Does anyone have a copy of the 2020 Advanced Maths paper, now that it is done? Thanks in advance.

Someone posted it (with answers) in the advanced maths thoughts thread. I'm not sure of the accuracy of the answers though. I hope this helps.

Questions 21 b) and 28 a) don't seem correct

 

[mmmm.]

Questions 21 b) and 28 a) don't seem correct

Yeah i didn't think they were right, for 28 a) It says at least one of the 2 are paid within the range, so wouldn't it be 1-(none paid in the range)??

Yes exactly, that's what I did

Was question 21 b) instantaneous rate of change?

This one seems wrong as well - isn't the derivative incorrect?

 

[Althacommie]

Is 29 b) correct? Because in the exam i got the value for c as just e

Wouldn't derivative be -28(1.5)^-0.4t

 

[demonicblackcat]

Wouldn't derivative be -28(1.5)^-0.4t

nah i think you can only do that if it's e

 

[Kangaaroo]

Wouldn't derivative be -28(1.5)^-0.4t

I got -28ln1.5*(1.5)^-0.4t

 

[Althacommie]

I got -28ln1.5*(1.5)^-0.4t

I got that too... the formula for the derivative of a^x is on the formula sheet so I'm pretty sure thats correct

 

[ItzZoni]

I got -28ln1.5*(1.5)^-0.4t

Yes i got the same result aswell

 

[ItzZoni]

also for 29 b I got c=e but not sure if that is correct

 

[Althacommie]

also for 29 b I got c=e but not sure if that is correct

Yeah i got c = e as well and a few of my mates did too

For question 28a) I did 1- (1-0.815)^2 = 0.965775
Also got e for 29b)
For question 21b) I did 70 x -0.4 x ln1.5 x 1.5^(0.4 x 4) = -5.93
Can anyone confirm these answers?
