Question

Help meeeeeeeeeeee pleaseeeeeeeeeeeeee!!

Answer 1

It would take
`2.7` seconds, correct to 1 decimal place/nearest tenth.

Explanation:

Step 1: Understanding the formula

The formula is given as
`h=16t^(2)`, where
`h` represents the height, and
`t` represents the time.

Step 2: Substituting and solving

The question asks for the time that would take when the height is
`117~\text{feet}`.

So, substitute
`117` for
`h` in the formula, since
`h` denotes the height:

`h=16t^(2)\\117=16t^(2)`

Now, let's solve the equation to find the time,
`t`:

`117=16t^(2)\\\\\text{Divide by 16 on both sides of the equation:}\\(117)/(16)=(16t^(2))/(16)\\\\\text{Simplify:}\\7.3125=t^(2)\\\\\text{Square root both sides of the equation:}\\√(7.3125)=\sqrt{t^(2)}\\\\\text{Calculate:}\\2.7 \approx t\\\\\text{Rearrange the equation:}\\t\approx2.7`

So, it takes about
`2.7` seconds to travel
`117` feet, according to the formula.
