Answer:
The variable t represents the time in minutes elapsed.
a(t) represents the altitude of the balloon at any minute t.
a(5.5) gives us information about the height of the balloon after 5.5 seconds
[tex]a(5.5)=127.5\ units[/tex]
Step-by-step explanation:
[tex]a(t) = 210-15t[/tex] is the equation that describes the height of the globe as a function of time in minutes.
In this case the variable t represents the time in minutes elapsed.
a(t) represents the altitude of the balloon at any minute t.
a(5.5) gives us information about the height of the balloon after 5.5 seconds
For example
[tex]a(5.5) = 210 - 15(5.5)\\\\a(5.5)=127.5\ units[/tex]
This means that when they have gone 5.5 seconds the height of the balloon is 127.5 distance units
On Edge the answers are 1. time after the balloon begins to descend 2. altitude of the balloon 3. altitude of the balloon after 5.5 minutes.
