Answer:

Step-by-step explanation:

Given that a rocket path is given by

h(x) = -4x^2 + 16x

When it hits the ground h(x) =0

Hence we get

-4x^2 + 16x=0\\x=0, 4

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

2) Given that

s(t) = -16t^2 + 48t + 280.

We have to find time t when height >280

s(t) = -16t^2 + 48t + 280>280\\\\t=0, 3

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

1.) You plug a number into the variable x. Then you will solve the equation for h(x) to find the time it takes for the rocket to travel the path given.

Answer:

  140°

Step-by-step explanation:

Angles 1 and 3 are "corresponding" angles, so are congruent.

  ∠1 = ∠3

  20x +60 = 30x +20

  40 = 10x . . . . . . . . . . . . subtract 20x+20

  4 = x . . . . . . . . . . . . . . divide by 10

  ∠1 = 20x +60 = 20(4) +60 = 80 +60

  ∠1 = 140°
