The answer would be 27. If ABC is 3 times the length of AB then it would be the same for AC.
<h3>Answer: </h3>
about 1.768 seconds
<h3>Explanation:</h3>
Since the phone is <em>dropped</em>, the first equation applies. The final height is assumed to be zero, so we have ...
... h(t) = 0 = -16t² +50
... 16t² = 50 . . . . . . . . add 16t²
... t² = 50/16 . . . . . . . . divide by 16
... t = √3.125 . . . . . . . take the square root
... t ≈ 1.768 . . . . . . . . round to milliseconds
Ratio=2 ft/s
ratio=2 ft/s * (1 mile / 5280 ft)*(3600 s / 1 h)=1.36363636.. miles/h≈1.36 miles/h.
Answer: 1.36 miles/h
It’s basically asking you to put it into the graph. Least to greatest.
