Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. what multiplicative rate of change should hal use in his function?

0.98

Step-by-step explanation:

The exponential decay equation in x years is given by :-

, where A is the initial amount and r is the rate of decay( in decimal).

Given: The initial investment = $10,000

The rate of decay = 2% = 0.02

Substitute these values in the above equation, we get

Here 0.98 is the multiplicative rate of change , the function will change by the constant ratio of 0.98 .

a)(x-2)^2+(y-1)^2=9
