The equation represents an ellipse.
which lines represent the approximate directrices of the ellipse? round to the nearest tenth.
x = −8.6 and x = 8.6
x = −6.6 and x = 10.6
y = −8.6 and y = 8.6
y = −6.6 and y = 10.6

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.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
