Front

What is the definition of exponential decay?

Back

Exponential decay is a decrease that follows the formula y = a(1 - r)^t, where a is the initial amount, r is the rate of decay, and t is time.

Front

What is the relationship between the angles in a parallelogram?

Back

Opposite angles are equal, and consecutive angles are supplementary.

Front

What is the definition of a logarithm?

Back
