Answer:
t represents time, which is the input of the function.
h(t) represents the altitude, which is the output of the function.
After 10 minutes, the hot air balloon is at 60 feet.
Step-by-step explanation:
Given the function; h(t) = 210 - 15t models the altitude of a hot air balloon over time t, in minutes.
It follows that;
t represents time, which is the input of the function.
h(t) represents the altitude, which is the output of the function.
To obtain h(10), we have;
h(10) = 210 - 15(10)
h(10) = 60 feet
