Step-by-step explanation:

The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
20m per second, because the difference between -50 and 250 is 300, and just divide 300 by 15, because distance/speed.
Answer:
55 degrees
Step-by-step explanation:
angle adds up to 360. your equation would be 360 = 2(125) + 2(angleN)
Answer:
M=47.99988
Step-by-step explanation:
M=1.33333(16+20)
=1.33333(36)
=47.99988
