Answer:
14
Step-by-step explanation:
If you graph out the parabola, you look for the maximum height of the parabola and it is 14.
Answer:
h_max = 324.09 ft
Step-by-step explanation:
The correct equation is;
h = 245t - 16t²
We are told that as the rocket descends, it deploys
a recovery parachute when it reaches 325 feet above the ground.
Thus;
245t - 16t² = 325
Thus;
16t² - 245t + 325 = 0
Using quadratic formula, we have the roots as;
t = 1.47s or 13.85s
We will pick the higher value.
Thus;
Maximum height will occur at t = 13.85 s
Thus, plugging in 13.85 for t into h = 245t - 16t², we have;
h_max = 245(13.85) - 16(13.85)²
h_max = 324.09 ft

Answer:
(x, y) = (-1.4, 1.6)
Step-by-step explanation:
The graph shows the solution pretty clearly. It seems no estimation is required.
I think it’s -1.69642857143
