Answer:
divide 16/20
Step-by-step explanation:
Answer:
The Slope is undefined and the y-intercept there is no y- intercept
Since x= 1/5 is a vertical line there is no y-intercept and the slope is undefined.
Given:
d(t) = 0.8t²
d(5) = 0.8*5² = 0.8 * 25 = 20
d(10) = 0.8*10² = 0.8 * 100 = 80
Average speed = distance traveled / time of travel
Average speed = 20 meters / 5 seconds = 4 meters per second
Average speed = 80 meters / 10 seconds = 8 meters per second
4 mps + 8 mps = 12 mps
12 mps / 2 = 6 mps the average speed in meters per second between 5 and 10 seconds.
The answer is A.
If you are asked to find an equation parallel to the other, make sure the equations have the SAME SLOPE, DIFFERENT Y-INTERCEPT
