Question

right after takeoff, a hot air balloon ascends at a constant rate of 400 feet per minute. complete the table to show the hot air balloons elevation after takeoff. \

$$\begin{tabular}{|c|c|} \\hline time since takeoff (min) & elevation (ft) \\\\ \\hline 0 & 0 \\\\ \\hline 1 & \\square \\\\ \\hline 2 & \\square \\\\ \\hline 3 & \\square \\\\ \\hline 4 & \\square \\\\ \\hline \\end{tabular}$$

Explanation:

Step1: Define elevation formula

Elevation = Rate × Time, so $E = 400t$

Step2: Calculate for t=1 min

Substitute $t=1$: $E = 400 \times 1 = 400$

Step3: Calculate for t=2 min

Substitute $t=2$: $E = 400 \times 2 = 800$

Step4: Calculate for t=3 min

Substitute $t=3$: $E = 400 \times 3 = 1200$

Step5: Calculate for t=4 min

Substitute $t=4$: $E = 400 \times 4 = 1600$

Answer:

Time since takeoff (min)	Elevation (ft)
1	400
2	800
3	1200
4	1600
