Step-by-step explanation:

[tex] - 24 \div 4 = \\ \frac{ - 24}{4} \\ = \frac{ - 12}{2} \\ = /frac{-6}{1}
Turn the triangle around, because you have to reflect it, if you need extra help lmk
The toy rocket hits the ground when h(t) = 0.
So, h(t) = 0 = -9t^2 + 81.
Solving the equation,
-9t^2 = -81
Dividing by -9
t^2 = 9
Taking the square root.
t = 3
The answer is 3 seconds.
104 because 10% of 80 is 8 years meaning 8+8+8=24 add 24 to 80 and ur answer is 104
I think its probaly going to be 6
