Question

The function h(t) = 210 – 15t models the altitude of a hot air balloon over time t, in minutes.

Answer 1

If we substitute 10 for t we get the height of the balloon after being in the air 10 minutes

h(10) = 210 - 15(10) = 210 - 150 = 60 

Answer 2

Answer:

on edg: t represents time, which is the input of the function, so we know that 10 is the time in minutes. h(t) represents the altitude, which is the output of the function after time, t. So, we need to substitute 10 into 210 – 15t in place of t. Simplifying 210 – 15(10), we get  that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.
