Maths P32 GT and paper discussion

i

When solving the differential:
The partial fraction:

N= A/0.02 + B/1-0.02N

And the RHS = 0.02t?

I did that, went on with this wrong equation, got wrong values
How much am I goig to score?
Someone please helppppppp
Just kill my curiosity
How much ouy of 8 eill I score?

guess u will lose 1-2 marks only

guess u will lose 1-2 marks only

Amen. 1 only

t = 50ln(0.8N/20(1-0.01N))

Wasn't it N in terms of t?

 

[Yousef123]

i guess it was N in terms of T and i got it N= 25e^0.002t -5

 

[A*(a*)]

t = 49.0

how can you solve the stated differential wqn for me please?

 

[Tulaib]

a--3 and b=4 I think

I dont remember the exact ans but it was like this

 

[Heyyy]

Can someone please tell me what was the complex number question like?

Nah.....it was t in terms of N.

Ofcourse!
Congratulations in advance

dN/dt = 0.02N(1-0.01N). N was 20 when t was 0.
Can someone solve the differential equation PLEASEE?

The value of c was c=ln(25) ..ryt ???
