Answer:
t = [0.493,4.2]
Step-by-step explanation:
The height of the rocket straight up into the air is given by :
![h(t)=-16t^2+85t+5](https://tex.z-dn.net/?f=h%28t%29%3D-16t%5E2%2B85t%2B5)
We need to find the interval the rocket be at least 43 feet above the ground.
![43\ge -16t^2+85t+5\\\\t\ge 0.493\ and\ t\le 4.82\ s](https://tex.z-dn.net/?f=43%5Cge%20-16t%5E2%2B85t%2B5%5C%5C%5C%5Ct%5Cge%200.493%5C%20and%5C%20t%5Cle%204.82%5C%20s)
So, the required interval during which the rocket is at least 43 feet above the ground is [0.493,4.2].
It must be an odd number because 3^7 is also shown as:
3x3x3x3x3x3x3
Which equals:2,187
2,187 is an odd number because the last number is a 7 which is odd.
