Unit 4 lesson
3. a model rocket is lauched from a roof into a large field. the path of the rocket can be modeled by the equation y=-0.8x^2+12x+25.8 were x is the horizontal distance, in meters from the starting point on the roof and y is the height , in meters of the rocket above the ground. how far horizontally from its starting point will the rocket land? round your answer to the nearest hundredth.
a. 25.80
b. 37.00
c. 17.24
d. 16.91
a physics student stands at the top of a hill that has an elevation of 56 meters. he throws a rock and it goes up into the air and then falls back past him and lands on the ground below the path of the rock can be modeled by the equation y=-0.04x^2+1.3x+56 were x is the horizontal distance in meters from the starting point on the top of the hill and y is the height in meters of the rock above the ground
a. 56.00
b 24.54
c. 57.04
d. 57.26
5. how many real number solutions does the equation have? 0=-4x^2+7x-8
a. no solutions
b. one solution
c. two solutions
d. infinitely many solutions
if anyone has the answers to the unit 5 lesson 10 unit test: quadratic functions and equations unit test it would be so

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?
