FLASHCARD QUESTION

Front

What is an exponential decay function?

Back

An exponential decay function describes a process where a quantity decreases at a rate proportional to its current value, often represented as y = a * e^(-kt), where 'a' is the initial amount, 'k' is the decay constant, and 't' is time.

FLASHCARD QUESTION

Front

How do you calculate total earnings with hourly wage and commission?

Back

Total earnings = (Hourly wage * Hours worked) + (Commission rate * Total sales). For example, if you earn $10/hour and 5% commission on $6,380 in sales, your total earnings would be $10*35 + 0.05*6380.

FLASHCARD QUESTION

Front

What is the significance of the decay constant in exponential decay?

Back

The decay constant (k) determines the rate at which the quantity decreases; a larger k means a faster decay.
