Question

Will give brainliest! The function graphed approximates the height of a nail, in meters, x seconds after a construction worker drops it from a skyscraper.

After about how many seconds is the nail 50 m above the ground?



3.2 s
3.5 s
3.9 s
4.1 s

Answer 1

1. As you can see in the graph attached, the x axis represents the time in seconds and the y axis represents the height in meters.

 2. Therefore, to solve this exercise and calculate how many seconds is the nail 50 m above the ground, you must draw a segment from 50 meters to the curve and then, you need to draw another segment from that point at the curve, to the x axis, as it is shown in the figure attached.

 3. You can conclude that the nail is 50 meters above the ground in 3.9 seconds.

 Therefore, the answer is: 3.9 s
