Answer:
see the attachment for a table
Step-by-step explanation:
A. The table is shown in the attachment. The solution to h(t) = g(t) is at a value of t that lies between 6 and 7. At t=6, h(t) > g(t). At t=7, h(t) < g(t). Since both functions are continuous, they must have equal values somewhere between t=6 and t=7. (Intermediate value theorem.)
__
B. The solution means the cannon balls will have the same height at a value of t between 6 and 7.
