The DePeppo children, Ann, Debbie, Damian, and Adam created a contest to test their athletic abilities and physical strength. They threw objects into the air to see who was the best. These four equations depict the travel of the objects they threw. 1=−162+62+10 y 1 = − 16 x 2 + 62 x + 10 2=−162+75 y 2 = − 16 x 2 + 75 x 3=−162+38+60 y 3 = − 16 x 2 + 38 x + 60 4=−162+20+10 y 4 = − 16 x 2 + 20 x + 10

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
