Leah took her friends for a ride in her hot air balloon. The function f models the height of the hot air balloon about the ground ( in meters) as a function of time (in minutes) after takeoff.

Question:

Leah took her friends for a ride in her hot air balloon.

The function r(t) = 210 - 15t models the height of the hot air balloon about the ground (in meters) as a function of time (in minutes) after takeoff.

Explain what r(10) means in the context of the real-world scenario, and how to find its value.

The balloon reaches a height of 160 meters, 10 minutes after take off.

Step-by-step explanation:

Given

Required

Explain r(10)

First, we calculate r(10)

Substitute 10 for t in

Hence: r(10) means that the balloon reaches a height of 160 meters, 10 minutes after take off.

x = 23.78
