If a figure has been dilated by a scale factor of 2, which transformation could be used to prove the figures are similar using the AA similarity postulate?
A reflection to map at least two sides of the image to two sides of the pre-image.
A series of dilations to map at least two angles of the image to two angles of the pre-image.
A rotation to map at least two sides of the image to two sides of the pre-image.
A series of translations to map at least two angles of the image to two angles of the pre-image.

A series of translations to map at least two angles of the image to two angles of the pre-image.

Step-by-step explanation:

we have 2 figures: △ABC and △A′B′C′

△A′B′C′ is the dialation of △ABC

we have to prove that the figures are similar using AA similarity

AA = (Angle-Angle)

Option D is correct.

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.
