They can but sometimes they dont
You have the maximum height happens at 5 seconds.
Replace t with 5 and solve for h(t):
h(5) = -0.2(5)^2 + 2(5)
h(5) = -0.2(25) + 10
h(5) = -5+10
h(5) = 5
The maximum height is 5 feet.

Answer:
0.65
Step-by-step explanation:
Confidence interval can be calculated using the Mean and Margin of error with M±ME where
- M is the average expected cold days of typical cold.
- ME is the Margin of error for the confidence interval.
In the question it is given that the researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
The minimum value in the confidence interval is M-ME =6.9
The maximum value in the confidence interval is M+ME=8.2
Then we get 8.2-6.9=1.3=M+ME-(M-ME)=2× ME
From this we get ME=0.65
