Solving the quadratic equation we conclude that:
- The maximum height is 45ft.
- The rocket is 18 seconds in the air.
<h3>
How to get the maximum height of the rocket?</h3>
The height of the rocket is defined by the quadratic equation:
The maximum height is what we get in the vertex of the quadratic equation, such that for this quadratic equation, the vertex is at:
So the maximum height is what we get when we evaluate in t = 9:
The maximum height is 45ft.
<h3>How to get the time in the air?</h3>
Now we need to solve the equation for the largest value of t:
Rewriting it, we get:
The maximum solution is what we get when:
0 = 90 - t*5
t = 90/5 = 18
The rocket is 18 seconds in the air.

The area of a regular hexagon is the 3 times the product of the apothem and side length.
22. 3*(6.1 m)*(7 m) = 128.1 m^2
23. 3*(11.3 in)*(13 in) = 440.7 in^2
24. 3*(9.5 ft)*(11 ft) = 313.5 ft^2
25. The area ratio is the square of the linear dimension ratio: (3/4)^2 = 9/16.

Answer:
2B / (mx) = y
Step-by-step explanation:
B = 1/2 mxy
Multiply each side by 2
2B = 2* 1/2 mxy
2B = mxy
Divide each side by mx
2B / (mx) = mxy / (mx)
2B / (mx) = y
