Un malabarista lanza una pelota al aire. La altura de las bolas, h, pies y tiempo, t, segundos se pueden representar por la ecuación h(t)=-16^2 +144. Parte A: Despues de 1.5 segundos cual es la altura de la bola?
Paret B: Suponga que el malabarista falla en agarrar una bola. En cual segundo llegó la bola al pizo?

i do not know this sorry : (

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
