Daniels print shop purchases a new printer for $35000. Each year it depreciates at a rate by 5%. Use an exponential function to find its approximate value after 8 years

The value of printer will $23,219.72 after 8 years.

Step-by-step explanation:

Given that, Daniels print shop purchases a new printer for $35,000.

Each year it depreciates at a rate 5%.

Exponential function:

P(t)= Price of printer after t years

= Initial price of printer

r= rate of depreciate.

t=Time

Here, = $35,000,r=5%=0.05, t=8 years

      =$23,219.72

The value of printer will $23,219.72 after 8 years.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
