Which figures demonstrate a rotation?

select each correct answer.

First and fourth figure.

Step-by-step explanation:

A basic rigid transformation is a transformation of the figure that does not affect the size of the figure . There are three basic rigid transformations:-reflections, rotations, and translations.

In first and last figure that is rotation about a point.

In second and third figure that is translation.

The second figure can be reflection or translation both.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
