Ahot air balloon descends to the ground. the function a(t) = 210 – 15t can be used to describe the altitude of the balloon as it approaches the ground. the time is in minutes. what does t represent? what does a(t) represent? what information will a(5.5) give?

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

Step-by-step explanation:

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

This means that when they have gone 5.5 seconds the height of the balloon is 127.5  distance units
