A football is kicked from the ground and follows the graph of the function y = –t2 + 3t, where y represents height and t represents seconds. At the same time, a drone is launched from a height of 4 feet and follows the straight path of y = –t + 4. At what time are the football and the drone at the same height? Options:
A. 2 seconds
B. 3 seconds
C. 1 second
D. 5 seconds

The height of the objects are the same after 2 seconds.

Step-by-step explanation:

In order to calculate at which time both objects have the same height we need to find the value of t that makes both equations equal. Therefore:

The height of the objects are the same after 2 seconds.

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9
