You can answer number 1 or 2 or both i just need with both and no one will answer my : ( 1.)in two or more complete sentences, explain how to find the time it takes for a rocket following the path, h(x) = -4x 2 + 16x, to hit the ground. 2.)a ball is thrown straight up from the top of a building that is 280ft high with an initial velocity of 48ft/s. the height of the object can be modeled by the equation s(t) = -16t 2 + 48t + 280. in two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.

Step-by-step explanation:

Given that a rocket path is given by

When it hits the ground h(x) =0

Hence we get

i.e. after 4 minutes the rocket hits the ground

2) Given that

We have to find time t when height >280

Between 0 and 3 seconds the object would be above the building.

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
