Question

What does the constant 0.15 reveal about the rate of change of the quantity?

Answer 1

Answer:

The function is decaying exponentially at a rate of 85% every year

Explanation:

0.15 is less than 1. This represents decay

Decay rate is 1 - 0.15 = 0.85 = 0.85*100 = 85%

t is given in years

Exponent is t, so it is every year.

The function is decaying exponentially at a rate of 85% every year
