Chuck stone is standing on top a higher platform. He fires a rock up into the air with his slingshot. Well it is in flight, the rocks distance above the ground is a quadratic function of time. At times one, two, and three seconds after he fired it, the rock is 68, 96, and 114 m above the ground, respectively. This shows that the graph of the quadratic function includes the points: (1,68) (2,96) (3,114) a.) write the particular equation from the rocks distance above ground (d) as a function of time (t).

b.) What is the highest the rock will be above ground?

c.) how high is the platform? (The rock is at the platform level when t = 0.)

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
