Question

once the hot air balloon reaches cruising altitude, it flies at an elevation of 2,400 feet. start by writing the starting elevation of the balloon after it reached cruising altitude, or the vertical intercept. the slope is 0. the vertical intercept is 2,400. e = \square + ? elevation = starting elevation + change in elevation

Explanation:

Step1: Identify vertical intercept

The vertical intercept is given as 2,400, which is the starting elevation when \(t=0\).

Step2: Identify slope/change rate

The slope (change in elevation per minute) is 0, so the change in elevation term is \(0 \times t\).

Step3: Build elevation equation

Combine starting elevation and change term.
\(e = 2400 + 0t\)

Answer:

\(e = \boldsymbol{2400} + 0t\)
The blank should be filled with 2400.
