Need help with math problem if do get 5 star

It is a reflection over the x-axis. Because it goes down, passing the x-axis.

D. Reflection across the x-axis.

Step-by-step explanation:

Reflection across x-axis has this coordinate notation:

(x, y) --> (x, -y)

(-8, 2) reflected across the x-axis would be (-8, -2)

Hence, D is the correct answer.

hope this helps and is right!! p.s. i really need brainliest :)

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

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.
