*1 ofa building at a point 6.5m above the in the previous questions and reaches a he hose. What distance is the (iv) A third hose sprays water onto the wall ground. The hose is the same height as maximum height of 8 metres when 12 metres from t building away from the hose? (_ 1.: '1 Building (ii) A second path of water from a fire hose is modelled by the equation ASSESSOR'S USE ONLY h = - - (d - 7)2 + 3, where h is the height of the water in metres and d is the horizontal distance of the water from the fire appliance in metres. What is the height of the hose above the ground? - 0.02 ( d - 7) + 3 - h Ing ( X - 7) 2 +3 4 = 2.02 (iii) A fire engine cannot get close enough to a small building 14 metres away that is on fire as there is a larger building in between. The larger building is 5 metres tall and halfway between the fire engine and the smaller building. If the fire is at the same height as the hose, what changes to the equation from part (ii) would need to be made to put the fire out? Note: the height of the hose does not change. Hose Large Building Small Building 14 metres The hose can be turned from the orginal position
