a rocket is launched in the air. the graph below shows the height of the rocket h in feet after t seconds. find the interval for which the rockets height is increasing.
Answer
Answer:
$0\lt t\lt20$
Explanation:
Step1: Understand the graph
The graph shows height $h$ vs time $t$.
Step2: Identify increasing - part
The height of the rocket is increasing when the graph is going up.
Step3: Determine the interval
From the graph, the height is increasing from $t = 0$ to $t=20$ seconds. So the interval is $0\lt t\lt20$.
