Answer:
No, the rock will not hit the water in 2 second but it will hit the water in t ≅ 2.17 second
Step-by-step explanation:
Let the distance be s in feet. i.e, where t is in second.
You drop a rock from a bridge that is 75 feet above the water.
Use the expression to solve for t:
Given: s =75 feet
then, substitute in the above expression:
or we can write it as:
or
⇒ t = 2.16506351 or t ≅2.17 second
Therefore, the rock hit the water in t≅2.17 second
we have given that 30 students .
we need to choose committee of 4 students .
so the formula used here .
where n is the total number of students.
and r is the student chosen from total.
so the possibility of choosing a commitee of 4 from 30 is
.
so there 27405 possibilities can exist.
