What’s the initial value and value after 13 years

we have given cost function which is exponential .

we need to find the cost of a car at time t initially and after 13 years .

we need to plug t=0 and t=13 in v(t).

.

and .

so the value of car is initially $20000 and after 13 years it was $2815.20.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

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.
