Kate is walking at a constant speed i front of a motion sensor. After 2 s, she is 2.5 m from the sensor, and after 4 s, she is 5.5 m from the sensor. Find the equation that describe Kate’s motion in the form d=mt+b

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
