<span>There are several ways to find the max of min of a quadratic equation.
Max occurs when t = -b/2a
t = -b/2a = -68/(2*-4.9) = 6.93 second
Max altitude = h(6.93) = 68(6.93)-4.9(6.93^2) = 235.92 meters

Answer:
see explanation
Step-by-step explanation:
solving the inequality
≥ 8 ( multiply both sides by 5 to clear the fraction )
x ≥ 40
Then from the values given
39 → No
40 → Yes
41 → Yes
factoring
Step-by-step explanation:
although all methods work, since it's x^2 it's easier to factor the x variable.
b + 2a + 2c = p or unknown answer,
b plus 2 times a plus 2 times c equals p the unknown answer
From there you use the strategy of guess and check to get your answer.
Answer:
131.25%
Step-by-step explanation:
1 = 100%
5/16 = 0.3125 = 31.25%
100+31.25 = 131.25%
