A toy rocket is shot vertically into the air from a launching pad 4 feet above the ground with an initial velocity of 128 feet per second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function h (t )equals negative 16 t squared plus 128 t plus 4. How long will it take the rocket to reach its maximum height? What is the maximum height? The rocket reaches its maximum height at nothing second(s) after launch. (Simplify your answer.) The maximum height reached by the object is 4 4 feet. (Simplify your answer.)

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?
