The amount of a radioactive material changes with time. The table below shows the amount of radioactive material f(t) left after time t: t(hours) 0 1 2 f(t) 100 50 25 Which exponential function best represents the relationship between f(t) and t? (1 point) f(t) = 0.5(100)t f(t) = 100 (0.25)t
f(t) = 0.25(50)t
f(t) = 100(0.5)t

a 10 percent increase

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

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.
