Question 1197659
<pre><font face = "consolas" color = "indigo" size = 3><b>
Hi  
A skateboarder jumps off a ledge. 
His path is modeled by the relation:
h= -0.8d^2 + 0.8d + 1.6
Graph:
 *[illustration 28.jpg].
a) What is the height of the ledge? 1.6m
b) Factor to find the zeros of the relation. d = 2 is the appropriate zero
c) At what point will the skateboarder land on the ground?
h = 0, Graph tells us: 
the skateboarder will land on the ground  2m from the ledge

Graph also tells us the max height jumped is 1.8m at .5m from ledge.
 Am using a FREE graphing software downloaded from  Padowan.dk
Wish You the Best in your Studies.
