• ### [Exponential Functions] A nail has punctured a tire, and it loses 1/10 of its air every 3 days?

Part A: What percentage of air is left after 20 days?

Part B: 7 days ago, it was at 25 psi, what is the original pressure?

Alright, I believe this is exponential growth. For part A, the equation should be P = (9/10)^(x/3) with x = 20

For part B, we are trying to solve for A = A_o(9/10)^(x/3) where A = 25 and x = 7. Am I right?

• ### Thoughts on ib in my situation?

haro my broskis. I am in tenth grade doing alp (pre-ib) and I am deciding on whether or not to do ib in the future. So I want to go to waterloo for engineering, but that's probably gonna need HL ib math, and I am just noticing now that I suck at math. My grade 10 math was 96, but I literally have a 70 rn in grade 11 functions. I also don't want to do french, but I heard the conversions for ib are worth it and will up my grades. At this point, IDK whether a normal school is going to be more beneficial to me or not. Anyways, if I don't do ib my mom is gonna force me to switch schools and I don't want to leave all my friends either. so to summarize:

-i suck at math but need hl to get into my top uni

-don't want to leave friends

higher ib conversion rates
