Answer:
X=2
Step-by-step explanation:
1/8 of getting double sixes or fives
Answer:
1/6 I think?
Step-by-step explanation:
The inequality is false.
If X = 11,
11 - 5 > 9 = false.
11 - 5 = 6
6 > 9 is a false inequality as 6 is not greater than 9.
Therefore, the inequality is false.
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
