In a certain state, automobile license plates start with one letter of the alphabet, followed by five digits . Find how many different license plates are possible if (a) the first digit following the letter cannot be 0 (b) the first letter cannot be O or I and the first digit cannot be 0

Limits and Discontinuity Notes Limits of sequences: 1/2 , k approaches ∞, and the fraction approaches 0. 0 is the limit as k approaches ∞. (2 -1)/2 , k approaches ∞, and the fraction approaches 1. 1 is the limit as k approaches ∞. Limits of average rates of change: finding final instantaneous velocity, calculate the rate of change over the last quarter second. Can’t find actual final velocity because can’t use r= ∆s/∆t when ∆t is 0, we just approach a value as ∆t approaches 0(this is a derivative). In general, limits help us discuss what happens when we let things get infinitely lim f (x)=L small, infinitely large, or close to some number. x→ c , as f(x) approaches L, as x gets clo
