If i got 100% until question 9 and got most of 9 wrong is it still possible to get an A?

but as r<1 you need to take the modulus and therefore it’s 1-|-.09| which is 1-0.9? then 10000x0.1 is 1000.

-0.9 is less than 1?

I got the wrong value of A for the sequence one, is there likely to be error carried forward?

Im pretty sure With A at 19,000, R=-0.9 and the sum of the first 12 terms, putting them together into the equation, you get 12824.29356. Not the 7,176 whatever you wrote..
6c) Is surely wrong, because i keep plugging it in, and i get the same 12,824 not 7176

Anyone who got 7176 has failed it’s deep

Omgggg yeah same where’s everyone getting 7176 from

What was question 7?

You’re a tutor? Did you take the exam? Or are you a teacher??
Basically want to know if you have the actual exam paper on you. Can’t remember the question so if you have it it would rly help
