If I charged my phone at the school charging station for 1 hour and 43 mins and 56 seconds, at 51%, and came back to 48%, what was my average percentage charged per hour?

This is very real I dealt with this at school lol.

Find the inverse of: y = log₃(2x+1)

Solution
x = log₃(2y+1)         switch x and y
log₃3ˣ = log₃(2y+1)    log base x of x = 1
3ˣ = 2y+1             log₃ cancels out
3ˣ-1 = 2y             subtract 1 from each side
(3ˣ-1)/2 = y          divide both sides by 2
y = (3ˣ-1)/2          switch sides to make it look pretty

That’s how I’ve learned at least, if you got something else blame the education system

Just remember to use the half-angle substitution and then it pops out naturally

But I think most people would just google it anyway…

One kid brings a Pi to school while another kid brings (2.5x10^-25)% of their father to school.

If the average mass of an adult male is 70kg, which kid brought more to school?

The kids aren’t even specified

daddy boi brought more because Pi is not a physical thing

But daddy boi didn’t bring a father.

what? what do you mean?
he ripped a chunk of the other kid’s dad and brought that to school?

Out of all off topic threads alive,Had to be the maths
