Exponential modelling

[slate birch]

I got part a and b correct, but im unsure on how to do part C - i've made the two equations equal to each other but i got 3/10 ln3 (T) = 1.5T, and therefore i can't get an answer. The markscheme says I need another constant but idk how to get it.

[vague cave]

Wdym u got 3/10

Show ur working out

@slate birch

I did weird shit and went back tried it I got the answer

@slate birch

[novel zealot]

I think you equate them

[novel zealot]

Wouldn’t k be be the same in part c

[vague cave]

Yea u just sub in the value of k hopefully u get the answer

[slate birch]

You need to find the value of K first

In the first part of the question

Being 1/2 ln3

[gleaming hamlet]

can u post the ms please

[slate birch]

will do

it just says 'correct method'

[desert nova]

yo

just equate bro

[slate birch]

yes ik

but i seem to always get T on both sides

and even if i dont

[desert nova]

lemme try it rq

[slate birch]

i still get the wrong answer

yeah some worked solutions would be nice please

[gleaming hamlet]

i got the right answer

i can send my workings out if u want

[slate birch]

yeah please

[gleaming hamlet]

sorry abt my handrwriting its a bit messy

[desert nova]

is t 10/4

[gleaming hamlet]

but lmk if u dont understand smt

[gleaming hamlet]

yep

he posted ms

[desert nova]

ah

[desert nova]

u made it made weird

everythings just a bunch of ln3s no?

[gleaming hamlet]

yhh i might have made it a lil longer i guess

its 3 marks but

yh

[desert nova]

i mean if it works it works

the way i did it was just cancelling hella logs

[gleaming hamlet]

yh at the end of my way u woulda cancelled out logs

[desert nova]

ah yh cus u get 2ln3/0.8 / ln3

fairs

[gleaming hamlet]

yep

just wrote it out to make it clear in the working

[desert nova]

yh nah ur right
