<span>H(t) = −16t^2 + vt + s
</span>
<span>H(t) = −16t^2 + 100t + 140
H(t) = 0 = </span><span>−16t^2 + 100t + 140
16t^2 - 100t -140 = 0
t = [100 +/- √ (100^2 -4(16)(-140) ) ] /(2(16))
t = 7.43 and t = - 1.18.
El que tiene sentido para la pregunta es t = 7.43 s.
Option B) 7 s (approximately)

Answer:
The probability of an eighth grader winning is 1/3

Answer:
0.636
Step-by-step explanation:
First off, we'll interpret the fraction bar to mean "divided by." This means that 7/11 is the same as 7 divided by 11.
Second, you have requested to see 2 decimal places in your answer, so we'll write the 7 as 7.00 instead (a 7 with 2 zeros after the decimal point).
Now, we'll just do what the fraction bar says: divide 7.00 by 11:
And that's about it! 7/11 written as a decimal to 3 decimal places is 0.636.
