A football is punted so that its path is described by the function h(t) = -4.9(t - 3.5)2 + 15 where h(t) is the height of the football, in meters at time t, in seconds. What time in seconds does it take for the football to reach its maximum height? Round your answer to the nearest tenth.

Step-by-step explanation:

You already have this set up to answer your question. This quadratic is in work form, aka vertex form, where the vertex is (3.5, 15). The first coordinate of the vertex is the time it takes to reach its max height, which is the second coordinate of the vertex. So it takes 3.5 seconds to reach a max height of 15 meters.

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5
