a football is kicked into the air. the height of the football in meters can be found by the quadratic function h(t)= −7t^2+35t where t is the time in seconds since the ball has been kicked.

1.) how high is the ball after 3 seconds?
2.) after how many seconds will the ball hit the ground?

tammy is drafting the windows for a new building. their shape can be modeled by the function h(w)=−w^2+9, where h is the height and w is the width of points on the window frame, measured in meters.
sketch a graph of the function and insert a picture of your graph

1.) find the width of each window at its base.
2.)find the width of each window when the height is 3 meters.
