the common ratio.
az = 5 and r = -3

a5 = ?

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?
