THINKING Jennifer is feeding ducks at a pond. She sits on a bench at the edge of the pond and throws bits of bread to the ducks. The path of a bit of bread can be modelled by the relation
h=-0.001w^(2)+90, where
hrepresents the height of the bread in centimetres and
wrepresents the horizontal distance from the edge of the pond in centimetres. a) From what height was the piece of bread thrown? b) How far from Jennifer does the bread land? Write a trinomial whose GCF is 5 .
