The distance that a free falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 75ft in 4 seconds, how far will it have fallen by the end of 8 seconds? Round your answer to the nearest integer if necessary.

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where 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? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m

The graph below shows the height of a projectile t seconds after it is launched. if acceleration due to gravity is -16 ft/s2, which equation models the height of the projectile correctly?
