(A)The distance a runner ran during training......
Answer:
C.) f(x) = −4x + 200
Step-by-step explanation:
Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.
In other words, the easiest way to solve this problem is to check the answers against the given data.
_____
If you want to write the equation from scratch, you need to find the slope. That is ...
(change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4
This matches only one answer, but you can go on to finish the equation by starting with point-slope form:
y -192 = -4(x -2)
y = -4x +8 +192 . . . . add 192, eliminate parentheses
y = -4x + 200 . . . . matches choice C.)

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 <span>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 </span>the nail is 50 meters above the ground<span> in 3.9 seconds.
Therefore, the answer is: 3.9 s</span>
