For the answer to the question above,
For the answer to Part A
H(t) g(t)
1 124 76.8
2 166 125.6
3 176 174.4
4 154 223.2
The solution is between 3 and 4 seconds because it can be seen that there was a shift in the trend between them. H(t) had higher values for the first 3 seconds. It can be seen that in 3 seconds, g(t) is already approaching H(t). Finally, at 4 seconds, g(t) surpasses H(t).
For the answer to part B
This means that between 3 and 4 seconds, g(t) was able to catch up to H(t) in terms of height. At H(t)=g(t), this gives 3.03 secs which is indeed between 3 and 4 seconds. Above 3.03 seconds, g(t) overtakes the height of H(t).
Answer:
quadrant III (3)
Step-by-step explanation:
If you graph the point it is located in quadrant III
The law of cosines states that, if 
is the angle between sides b and c,
So, plugging our values, we have
This is equal to
20/q = 7/9
20×9 = 7q
7q = 180
q = 180/7
