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? altitude of the balloontime after the balloon begins to descendtime it takes the balloon to reach the ground what does a(t) represent? altitude of the balloontime after the balloon begins to descendtime it takes the balloon to reach the ground what information will a(5.5) give? time it takes the balloon to reach an altitude of 5.5 feetaltitude of the balloon after 5.5 minutestime it will take the balloon to reach the ground, or 5.5 minutes

a(t) = 210 -5t

(1) What does t represent?

As its given t is in minutes so t represents time.

altitude of the balloon: is incorrect as that will be represented as a(t) as thats altitute

time after the balloon begins to descend

This is correct answer

time it takes the balloon to reach the ground:

This is incorrect as it will be some fixed time when balloon will reach ground level

(2) What does a(t) represent?

altitude of the balloon

This is correct answer

time after the balloon begins to descend

This is incorrect, time is represented by t

time it takes the balloon to reach the ground

This is incorrect as it will be some fixed time when balloon will reach ground level and not altitude

(3) What information will a(5.5) give?

time it takes the balloon to reach an altitude of 5.5 feet

This is incorrect as a(5.5) means altitude a at time t =5.5

altitude of the balloon after 5.5 minutes

This is correct as a(5.5) means altitude a at time t =5.5

time it will take the balloon to reach the ground

This is incorrect as a(5.5) means altitude a at time t =5.5

5.5 minutes

This is incorrect a represents altitude and not time.

a(5.5) means altitude a at time t =5.5

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.
