A clothing manufacturer uses the model a= Vf+4 - V36 - f to estimate

the amount of fabric to order from a mill. In the formula, a is the number of

apparel items (in hundreds) and f is the number of units of fabric needed. If

400 apparel items will be manufactured, how many units of fabric should be

ordered?

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

he kicked it up? is this the answer ?
