Mrs. sage will print a copy of the class alphabet book for each student. the book is formatted in1/2 pages with a title page, a page for each letter and an end page. if there are 70 students, how many reams of paper will mrs. sage need for the books? (1 ream=500 sheets)

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
